**Recommendations to others considering Thunderbird:**

You can combine a lot of your emails into one platform, but dont expect it to look that pretty. It functions. But it doesnt work like gmail. It does not have proper email "trees" like gmail threads, or this or that. But it does have 'themes' that can change the look. I use a dark theme.

  ### 4. Opensource Mail client

**Rating:** 4.0/5.0 stars

**Reviewed by:** Timothy S. | Software Programmer, Internet, Small-Business (50 or fewer emp.)

**Reviewed Date:** March 17, 2019

**What do you like best about Thunderbird?**

The best thing about Thunderbird is that it is a software created by the Mozilla foundation, this means that you know with certainty that the software does not have any kind of trap to steal information from your emails since Mozilla does all its Open source projects.

The application supports the most important domains and you can add as many emails as you need, the auto assistant configures most of the domains without almost user intervention, it is only necessary to add the email and password.

It is also possible to modify the internal options of the mail client as the visual theme that it has by default since it supports the themes of the browser Firefox (also created by Mozilla), these themes or also called "people" modify the color and image of the header of the application.

**What do you dislike about Thunderbird?**

- A negative aspect of the application is that, as is otherwise normal, the synchronization becomes somewhat slower the greater the number of emails to synchronize in your application.
- The application does not support language change without having to resort to reinstalling it using Thunderbird with the language package we need, it would be useful if the application incorporated all the languages and could be changed through options.

**Recommendations to others considering Thunderbird:**

Thunderbird is an Open source application and 100% free, I recommend it because using this tool you can be sure that your emails will not be spied on. You can add hundreds of emails from any domain that will be detected automatically by the configuration wizard.

**What problems is Thunderbird solving and how is that benefiting you?**

With Thunderbird saves a lot of time because with a single click of mouse we can access any email that we have added to the application, it is also possible to access local emails already deleted so it adds extra security to have backups available on our computer. In summary, the main benefit of using Thunderbird is to have all my emails organized in a quick and easy way.

  ### 5. It is our corporate email service

**Rating:** 3.5/5.0 stars

**Reviewed by:** Luis Eduardo M. | Consultor de Proyectos en Telecomunicaciones, Enterprise (> 1000 emp.)

**Reviewed Date:** March 13, 2019

**What do you like best about Thunderbird?**

Thunderbird is the messaging service implemented corporately by the company where I work. I use it daily to review, send and organize emails quickly and very easily. Given the large number of existing workers I usually use the address book in which they are registered at the time of writing emails. To maintain an order in the information sent and received every day, I take advantage of storing and discriminating the emails in subdirectories located within the folder called "Local folders", which allows me to more efficiently locate a specific email when it is required and thanks to the search engine enabled in the application.

**What do you dislike about Thunderbird?**

One of the things I do not like about this tool is that the text editor is not very easy to handle when writing reports with pictures or images extracted from other digital documents where the same separation between lines, size and type of letters and design of the pictures, as it is done in editors such as Word for example. It has happened to me that I want to write a title with typeface and text with another type, and the text editor makes its own discrimination. This was easier when I did it in Outlook. Another option that is not viable is that you cannot attach emails directly from the folders but you must save the hard disk as a file and then attach them to the mail.

**Recommendations to others considering Thunderbird:**

If you prefer softwares and implementations under the Free Software model, this is an option that you can put into practice.

**What problems is Thunderbird solving and how is that benefiting you?**

In general, it is an electronic messaging service with functional options that allow company employees to maintain communication via email, including reports, diagnostics, reviews, reports and status on the operation of the company in its different operational areas. Personally, it has allowed me to execute my daily work that is supported daily via emails. However, I prefer to work with Outlook, for its kindness when it comes to making emails as reports without altering their images and Excel tables.

  ### 6. Thunderbird, large online message tray

**Rating:** 5.0/5.0 stars

**Reviewed by:** GABRIEL J. | I am a virtual user of online calls through Zultys Mxie, Mid-Market (51-1000 emp.)

**Reviewed Date:** May 30, 2019

**What do you like best about Thunderbird?**

Today, we manage thunderbird as the only email manager based on a gmail domain, configured in this way in these terminals. It is simple to use and pleasant for all our staff of connections in the different departments of our company. It is fantastic only because it can be entered permanently from a terminal, for security and data fidelity is the best. In addition to all its foreign functions as a complement, it helps to keep track of all messages received by customers


**What do you dislike about Thunderbird?**

We have not been able to make the multiuser configuration, therefore it is not viable to configure one more session for the administration of emails of our staff

**Recommendations to others considering Thunderbird:**

I recommend thunderbird as an electronic mail control agent, I feel better every day with the control of emails, as well as the sending is easier for all contacts of the company

**What problems is Thunderbird solving and how is that benefiting you?**

Daily we have solved the organization of the messages of our clients with thunderbird. The opinion of our clients and ours is that every day it is better to manage our emails from the cloud with this tool.

  ### 7. Thunderbird, Free email client

**Rating:** 4.0/5.0 stars

**Reviewed by:** Miguel R. | Software Engineer, Computer Software, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 28, 2019

**What do you like best about Thunderbird?**

I love using Thunderbird because it greatly relieves my workload and staff to manage all my personal and work emails at once, in my Personal Thunderbird I have more than 4 emails that I use at the same time and in my company some more.

The best thing about Thunderbird for me is the possibility of adding the emails to the application in a quick and simple way in which you only have to enter the email and password and then the application automatically configures the local mail service.

Other interesting features of Thunderbird is the possibility of locally storing emails to be able to consult them without connection, this is really useful if your domain limits the mail tray to a certain number of emails.

**What do you dislike about Thunderbird?**

It is very difficult to find negative aspects in such a simple application and that the only thing it does is to manage emails but unfortunately I have found one that is very annoying:

When you add several different emails from the same domain it is very possible that the application tries to update everything at once saturating the domain with repeated requests so we will end up being limited and we will have to log in through the browser to verify the email account through SMS or alternative mail, this has happened to me with outlook.

**Recommendations to others considering Thunderbird:**

I recommend using the application if you are a user or professional who loses a lot of time daily in checking their emails on different websites. Using Thunderbird you can consult everything in minutes and without licensing fees.

**What problems is Thunderbird solving and how is that benefiting you?**

Thunderbird is very useful to manage different email accounts in a fast and uncomplicated way since it frees us from the problem of having to access each web site to log in to our email specifically.

  ### 8. Great mail client 

**Rating:** 4.0/5.0 stars

**Reviewed by:** Henry S. | Support Specialist, Small-Business (50 or fewer emp.)

**Reviewed Date:** March 03, 2019

**What do you like best about Thunderbird?**

Thunderbird is compatible with all existing e-mail domains, and the application is very simple since we only have to insert our e-mail and password to automatically configure our inbox, although it is possible to find some that do not they are detected automatically so it is necessary to enter the configuration parameters manually to make it work.

It supports the possibility of storing your emails locally so that even in case of connection loss we can review the received emails. It also includes basic features like deleted from remote or local emails, marked as unread, spam etc ...

And very important by default disables images and potentially malicious content for our machine so we can check our mail without fear of getting infected by viruses.

**What do you dislike about Thunderbird?**

What I do not like is that the mobile application is not synchronized with the desktop application, nor the reverse. So when you delete an email from one of the two clients this is not updated immediately at the other end.

I would also like the possibility of being able to use security methods like 2FA to access the emails since some of my accounts contain sensitive information such as bank details.

**Recommendations to others considering Thunderbird:**

Thunderbird is a recommended application for all those people who handle more than one email in their work or personal life since using Thunderbird saves a lot of time, in addition the application is free as it is evident when created by the mozilla foundation.

**What problems is Thunderbird solving and how is that benefiting you?**

The problems that are solved are that we can access all our emails in real time without losing time using the web browser to enter each of the emails, thus losing work time.

  ### 9. Our e-mail carrier pidgin is Mozilla Thunderbird ⚡🐦 

**Rating:** 5.0/5.0 stars

**Reviewed by:** inTec M. | Targeted Marketing Specialist, Information Technology and Services, Small-Business (50 or fewer emp.)

**Reviewed Date:** May 16, 2019

**What do you like best about Thunderbird?**

The fact themat thunderbird is open source and managed by Mozilla holds a lot of value for us as a business. Mozilla has an incredible community and a very good reputation. Being they're open source, you don't have to worry about shady practices or even just the simplicity of use of their software over other mail clients like outlook. Thunderbird is light weight and has plug in and calender capabilities. 

**What do you dislike about Thunderbird?**

I have been using Mozilla thunderbird for almost 20 years when it replaced outlook and I can say without pause or question that I've never had an issue with thunderbird or any of the Mozilla products we use like Firefox. 

**Recommendations to others considering Thunderbird:**

If you're considering trying out thunderbird I would suggest just giving it a try. Considering it is free software and is incredibly easy to set up, there's really nothing to lose but the benefits you'd gain by switching to thunderbird mail client - a product of  Mozilla

**What problems is Thunderbird solving and how is that benefiting you?**

We are able to organize communications between various customers over multiple email addresses by setting rules and actions to automatically perform tasks such as sorting a particular customers mail into their own folder so we can easily reference their information from one place  and without having to sort through mounds of emails and searches. It saves us time and helps us stay organized and to operate more efficiently. 

  ### 10. Control all your emails with thunderbird

**Rating:** 4.0/5.0 stars

**Reviewed by:** david R. | Software Programmer, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 16, 2019

**What do you like best about Thunderbird?**

I am using Thunderbird because due to my work I currently have to manage almost 12 different emails and Thunderbird has worked perfectly with all the domains without any type of problem or error.

The application has a lot of advanced configuration options but if you do not need to configure the emails manually, you do not have to waste time with it, and the best thing about Thunderbird is that, at least in my case, all the domains are auto-detected. correctly and I just had to put the email and the password!

Incredible now I can manage all email accounts at once and without wasting time opening and closing sessions with several different accounts.

Other things that I liked about thunderbird:
- You can configure it to manage the mail locally so if you lose the connection you can continue reading emails
- You can also write emails without connection and send them, when the connection returns they will be sent automatically.
- The application is open source and free, offered by the Mozilla foundation (the same created from firefox)
- I work in Windows and MAC although it is also available for Linux users
- Thunderbird is very stable I have not had lag or crash problems in the application

**What do you dislike about Thunderbird?**

What I did not like about Thunderbird is that if you add several accounts from the same domain (outlook for example) when making simultaneous connections to check the mail, Microsoft Outlook activates the security of the account and blocks the login until you enter from the web and deactivate it.

**Recommendations to others considering Thunderbird:**

I recommend using Thunderbird if you have many emails to manage either personal or professional and do not want to waste time opening and closing sessions on the Internet. Also Thunderbird is open source and free.

**What problems is Thunderbird solving and how is that benefiting you?**

In the company I have to manage more than 12 emails and I was losing a lot of time trying to review them all one by one, opening and closing sessions. Now thanks to Thunderbird I just lose 10 minutes of my time and I can do it in real time.

  ### 11. An email manager that surprises

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Renewables & Environment | Small-Business (50 or fewer emp.)

**Reviewed Date:** May 08, 2019

**What do you like best about Thunderbird?**

Thunderbird gives us the ability to have all our email accounts in an organized manner and easily manageable. Adding accounts is very simple, as the configuration is practically done by Thunderbird itself. We have a great advantage like seeing all accounts in a single inbox or individually, making backups, keeping track of our contacts, etc. It is completely free and we can download it directly from their website easily.

**What do you dislike about Thunderbird?**

I find no negative points in Thunderbird. The interface seems a bit outdated (personal opinion) but the important thing is that it performs all functions well.

**Recommendations to others considering Thunderbird:**

If you are a frequent user of multiple email accounts, I recommend it. Mainly in offices and places where many communications with clients can be handled via email. Since it's free, you lose nothing by trying it, you will see all the advantages it offers you.

**What problems is Thunderbird solving and how is that benefiting you?**

When you have many email accounts in the company, it is complicated to carry them all and manage them correctly. With Thunderbird, this does not happen; management becomes easy and controlling everything is simpler. Finally, you save time and organization, as you can create different folders according to interests and archive emails.

Thunderbird is a free mail client with many features. The main advantage of this solution is that we can have any mail without any significance from which the service provider comes. Thunderbird has a simple interface, which will surely be suitable for all users, even the less technical ones. In this solution, the possibility of opening e-mails in new cards also deserves a plus.

I do not like the design of the program, which should be significantly refreshed.

**Reviewed by:** Theresa H. | Software Developer, Computer Software, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 12, 2019

**What do you like best about Thunderbird?**

At work and at home I have been using Thunderbird for some time, thanks to Thunderbird I can manage my company and personal mail at the same time without having to enter the respective websites of each service.

The best of Thunderbird for me would be:
- Multi platform application that allows to run on Mac, Windows or Linux
- Many years of development that make Thunderbird a completely stable application
- Simple interface
- Requires little hard disk installation space
- Low CPU and RAM consumption

**What do you dislike about Thunderbird?**

There's nothing wrong with Thunderbird, it's a mail application and it works perfectly, I have not seen any bug so far. I would say that they could improve their interface or make them support plugins or themes.

**Recommendations to others considering Thunderbird:**

If in your work (or at home) you handle a lot of emails I recommend that you use Thunderbird because you will gain a lot of time to spend on other things. Before I had to consult 6 email accounts one by one and I lost almost 30 minutes a day, now in 5 minutes I can check all my mail! And the best part is that you do not have to pay anything for the license because it's free

**What problems is Thunderbird solving and how is that benefiting you?**

Best of all, it is free and able to add hundreds of custom email addresses, a great alternative for Microsoft Outlook. Lightweight software.

**Reviewed by:** Verified User in Renewables & Environment | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 28, 2019

**What do you like best about Thunderbird?**

Thunderbird offers a simple and secure way to manage your email accounts. We can set up multiple accounts easily, almost without configuring anything. We can have unified inboxes or separate ones for each account. Contact management, fast sending and receiving are other advantages. And best of all, it is completely free.

**What do you dislike about Thunderbird?**

I can't find any negative points. It works correctly. Perhaps the graphical interface could be updated a bit, but it's not necessary for its proper functioning.

**Recommendations to others considering Thunderbird:**

I recommend everyone to try it. If you are a single email account user, it might not be worth it, but if you manage multiple email accounts in your company or home, it becomes indispensable. It's free, you lose nothing by trying it, it will surprise you.

**What problems is Thunderbird solving and how is that benefiting you?**

Before, it was complicated to have to check all the email accounts one by one. With Thunderbird, you can see them all at a glance and save a lot of time. Better management of email communications in general.

  ### 18. Maybe the best client for your business and personal mails

**Rating:** 4.5/5.0 stars

**Reviewed by:** Seth M. | Support Specialist, Automotive, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 10, 2019

**What do you like best about Thunderbird?**

Thunderbird is a tool we have been using in our business (and I personally also in others) for some time because Thunderbird allows you to manage dozens of company emails, personal or of any kind without problem.

Technically the application is very stable although it is normal because Thunderbird has many years of development so it could be said that it is practically a finished product, although it is still being updated and adding new functionalities.

The requirements of Thunderbird are really low or nonexistent, opening the application will not involve any work for your computer.

Another Thunderbird thing that I like is your work team belongs to the Mozilla foundation that works for open source software. It is also multi platform supporting all the most used operating systems currently on the market such as Windows, Mac or Linux.

**What do you dislike about Thunderbird?**

Sincerely the application does not have any serious flaws, as I said it has many years of development and is free of important bugs.

If I have to say something that I would like you to implement is some way of applying themes to change the aspect of the application.

**Recommendations to others considering Thunderbird:**

I recommend you use Thunderbird if you are looking for a way to access all your emails without wasting time checking one by one in their respective web platform.

**What problems is Thunderbird solving and how is that benefiting you?**

In my work as a support I receive dozens of emails of different types every day, clients, work companions, bosses etc .. having different emails if I had to check all one by one I would lose a lot of time that I do not have, thanks to Thunderbird I can always know if a new email has arrived without worrying about what account it belongs to because it manages all the accounts as if they were one.

  ### 19. Amazing email client

**Rating:** 4.5/5.0 stars

**Reviewed by:** Antonio B. | Software Programmer, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 10, 2019

**What do you like best about Thunderbird?**

For me the best thing about thunderbird is the possibility of managing all your email accounts at the same time, for example I have two business emails, two personal emails, and three for other purposes. I can receive several emails at a time in different accounts without problem, to do it through the browser should have several tabs open and even close and open sessions several times to check all my emails.

The best of thunderbird:
- Multi platform (Linux, Windows and Mac available)
- Open source and free
- The Mozilla foundation and its philosophy always in favor of open source software and the comfort of knowing that you are not being spied
- Supports almost all existing email services by default, if it does not work you can always choose the manual settings.

**What do you dislike about Thunderbird?**

What I do not like is that some services limit the number of requests for the same email domain, if for example you have two outlook emails you will not be able to consult them at the same time as Microsoft limits a connection every several minutes. Obviously this is not a problem of thunderbird but I wonder if it is possible to solve it via software.

**Recommendations to others considering Thunderbird:**

After trying several mail clients I must say that Thunderbird is totally superior to the rest in all aspects, especially in the most important is the price.

Definitely I recommend Thunderbird if you need to manage several emails and you are looking for a free solution that works reliably.

**What problems is Thunderbird solving and how is that benefiting you?**

We work in a large department and manage several email accounts both company and personal and we need to be aware of the latest news that come through the mail, thanks to Thunderbird we can manage all our mail and free of charge.

  ### 20. The best alternative to Outlook for a desktop mail client. 

**Rating:** 5.0/5.0 stars

**Reviewed by:** Andrew L. | Online Marketing Consultant, Small-Business (50 or fewer emp.)

**Reviewed Date:** February 09, 2019

**What do you like best about Thunderbird?**

Web mail clients, such as GMail are adequate if you're managing one inbox but if you need to monitor a number of email addresses all day, every day and without cluttering up your web browser with lots of open tabs then a desktop client is what you need. Free and open source, Thunderbird fills the gap that many Outlook Express and Windows Mail users have without the need to turn to bloated Outlook. 

Also development of this software is pretty much frozen, except for the occasional update. The developers aren't messing with it for the sake of it, bloat isn't being added, much loved features aren't being taken away. The Thunderbird you use today is the one you'll be using in a few months and that's great because, seriously, how many more features does an email client need!

**What do you dislike about Thunderbird?**

The add-ons and themes directory could do with clearing out - there are too many extensions that are incompatible with the latest version. 


**Recommendations to others considering Thunderbird:**

There's an extension that will let Thunderbird's calendar sync with G Suite! It's brilliant!

**What problems is Thunderbird solving and how is that benefiting you?**

Thunderbird, as desktop client, makes it far easier to manage and access multiple mailboxes than webmail. If you have to look at 2 or more mailboxes all day, this is the way forward. 

  ### 21. Your emails perfectly organized

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Renewables & Environment | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 13, 2019

**What do you like best about Thunderbird?**

Thunderbird presents itself as a very professional email manager, to the point that, in my opinion, it far surpasses the rest of its competitors on different platforms, such as Outlook or Mail. The configuration of accounts, backups, sending and receiving speed are perfect, with everything being very easy to handle. Contact management is also very good.

**What do you dislike about Thunderbird?**

I don't see any negative issues. Everything works well and quickly, doing everything it promises. Perhaps it lacks some customization, but that is completely secondary; the important thing is its proper functioning.

**Recommendations to others considering Thunderbird:**

It's not that I recommend it, it's that I consider it essential. If you have to synchronize one or several email accounts and use a manager, Thunderbird is the best option without a doubt. The best part is that it's completely free.

**What problems is Thunderbird solving and how is that benefiting you?**

The management of emails in the company is perfect, especially if you have multiple accounts to manage. Being able to have a common inbox for receiving emails makes it a very good tool.

  ### 23. The best free (as in freedom and beer) email client

**Rating:** 5.0/5.0 stars

**Reviewed by:** Miguel Angel A. | Instructor Professor, Enterprise (> 1000 emp.)

**Reviewed Date:** January 25, 2019

**What do you like best about Thunderbird?**

There are four great things about Thunderbrid:

1) It's very easy to setup new accounts. If you use a well known email provider, like Gmail, Microsoft or Yahoo!, Thunderbird is able to automatically set up everything for you. All you need to do is click on the authorize button it shows you to enable Thunderbird to login to your account. Setting up an account on a private e-mail server is also very easy to do.

2) It's very easy to make backups: just copy your profile folder anywhere and you're good to go. This also makes it very easy to migrate your Thunderbird data to another machine.

3) It has a full-featured search function: You can search by keyword or phrase or by regular expressions, and you can limit your search to certain accounts, or search by participant in any conversation, among many other things.

4) It protects your privacy: media files in your mail are not downloaded and shown by default so you cannot be tracked when checking your email. This can be disabled on a per-mail, per-account or per-profile basis if you want to, however.

**What do you dislike about Thunderbird?**

Two things:

1) It can consume a considerable amount of hard drive space (my Thunderbird profile is about 10 GB after 4 years of use) since it downloads and caches any mail that you open. If you just check the headlines then it doesn't download anything, however.

2) There is no minimize-to-tray function. This was easy to fix in previous versions of Thunderbird with an extension (Thunderbird extensions are just like Firefox browser extensions), but the latest versions (from 2018 onwards) do not support any minimize-to-tray extension.

**Recommendations to others considering Thunderbird:**

Just like it's sibling Firefox, Thunderbird requires a moderately modern machine to work. Other than that, it's both free, full-featured and easy to set-up so trying it out should not be any problem at all.

**What problems is Thunderbird solving and how is that benefiting you?**

I use Thunderbird to handle all my email accounts, including my personal account Gmail account and several work related Gmail and institutional  accounts. Thunderbird is compatible with SMTP, IMAP and POP3 e-mail servers so it works with any provider, like Google, Microsoft or even your own servers

  ### 24. Manage your email efficiently

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Renewables & Environment | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 09, 2019

**What do you like best about Thunderbird?**

Thunderbird offers us the possibility to set up and manage our email accounts in an easy and simple way, allowing us to configure each one of them easily and without much hassle. It supports both POP3 and IMAP, and the accounts are practically self-configuring; we simply need to provide our email and password. The management panel is also easy to understand, and we can check each account separately or have a general inbox for all, which makes it very convenient.

**What do you dislike about Thunderbird?**

Everything seems correct to me. I don't see any operational faults and it does everything it needs to do. It's not difficult to handle or install. Honestly, you can't find many faults with it, everything is very correct.

**Recommendations to others considering Thunderbird:**

It is the best current email manager, so I have to recommend it to everyone. Additionally, it is completely free, which invites everyone to try it and see the capabilities it has. A great community behind it to solve doubts and constant updates make Thunderbird a must-have for any user who works with email accounts.

**What problems is Thunderbird solving and how is that benefiting you?**

It greatly facilitates work and email management, especially when you have multiple accounts. The transfer from a backup or another system like Outlook is simple, which makes migration not a headache.

  ### 25. The best email manager

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Renewables & Environment | Small-Business (50 or fewer emp.)

**Reviewed Date:** April 08, 2019

**What do you like best about Thunderbird?**

We are undoubtedly facing the best email manager that exists. Neither OSX's Mail nor much less Microsoft's Outlook. Thunderbird beats them all by a significant margin. Very fast synchronization of the accounts you have set up, contact manager, almost automatic account configuration, easy import and export of copies... and much more. The best part is that it's free.

**What do you dislike about Thunderbird?**

It's hard to find anything negative about Thunderbird. Everything it does, it does well, quickly, and without issues. It's one of the few software programs where I can't point out anything negative.

**Recommendations to others considering Thunderbird:**

I recommend it without hesitation, it is the best email manager you will find. It has a good community behind it and is from the creators of Firefox. Constant updates and always improving.

**What problems is Thunderbird solving and how is that benefiting you?**

When you have multiple email accounts, you need something to manage them and not go crazy, especially to avoid having to log into each one individually. With Thunderbird, this is possible and helps a lot in the process.

There is also a unified inbox, while not practical for my use, but could be to others.

Thunderbird was not maintained for several years but has recently been given a much-needed update. Unfortunately, many of my add-ons are not currently working.

**Rating:** 3.5/5.0 stars

**Reviewed by:** Robert  S. | Small-Business (50 or fewer emp.)

**Reviewed Date:** October 07, 2018

**What do you like best about Thunderbird?**

Thunderbird is a good program that manages different email clients, both business and personal. It is capable of managing multiple mail accounts without any problem. It divides them into tabs and when clicking, it expands the inbox and all the other folders in the mail.
It syncs very quickly and emails are received in real time.
Every time you receive an email, a popup appears and it sounds. It is very useful if you are waiting for mail or if you are away from the computer so you can hear it immediately.

**What do you dislike about Thunderbird?**

I do not like the lack of updates that this program has. There are many things that can be improved, especially the slowness of the program if there are many emails in the inbox. They must be sorted or erased so that it works smoothly.
I do not like the mail display to be below, and there is no tab or popup to read the mail.

**Recommendations to others considering Thunderbird:**

I would recommend to everyone that you need a free program to control, read and respond to electronic mail. To be free, it is one of the best ones on the market.

**What problems is Thunderbird solving and how is that benefiting you?**

Mainly, in my company we use it as the main program to read and send electronic mail. It is a great program that for now serves us quite well.

I do not like how difficult it is to change email. If you want to delete an account it is very difficult. It has so many options and tabs that it is not at first sight.

**Recommendations to others considering Thunderbird:**

I would recommend to everyone that you need a program to manage email and that it is easy to install, easy and very easy to use. It really is fantastic.

**What problems is Thunderbird solving and how is that benefiting you?**

In my company, we use this program as the main client to receive emails. All the employees use this client and they are all very happy because it is very easy to use and quite intuitive.

  ### 50. One of the best free software to manage emails

**Rating:** 3.5/5.0 stars

**Reviewed by:** Juanjo R. | Small-Business (50 or fewer emp.)

**Reviewed Date:** October 01, 2018

**What do you like best about Thunderbird?**

- We use this software at work to have all the emails of the employees in the same computer, so that we never lose time in answering the clients effectively.
- It is free and has many features and add-ons.
- almost everyone in our company knows how to use it. It has a very intuitive interface, and for a typical use (write, answer, delete emails) is perfect.
- It has a fairly large community because the program is open source.

**What do you dislike about Thunderbird?**

- Sometimes the program stops suddenly and crashes.
- When you have to dump a lot of information in the emails (copy, delete multiple files or upload them) sometimes it goes very slow.
- Programmers tend to update their interfaces to make them more accessible and modern, but it seems that thunderbird programmers do not update the software as they should.

**Recommendations to others considering Thunderbird:**

Easy, free email manager with lots of possibilities. For a company it is perfect to manage all the accounts of employees

**What problems is Thunderbird solving and how is that benefiting you?**

- It allows us to keep order with emails to always follow guidelines and never waste time and get along with customers
