You can add not only personal e-mail accounts but also business accounts. Usually configuration is automatic but there is also a manual option. You can personalize some features such as notifications and templates. **What do you dislike about Thunderbird?** Interface could be less simple and an app version for mobile phones would be great. **Recommendations to others considering Thunderbird:** In conclusion, I definately recommend Thunderbird. When dealing with dozens of messages daily, having all accounts together, makes reading and answering e-mails a lot faster. In addition, you can have your personal and business e-mails together, but no mixed. **What problems is Thunderbird solving and how is that benefiting you?** When you have accounts from different servers you have to open several web pages and it can be tedious and time-consuming. With thunderbird you have everything in one place and there are different filters if you need to find an specific message fast. ### 29.

Sad **Rating:** 1.5/5.0 stars **Reviewed by:** Gabriel P. | Auditoría y Planificación, Small-Business (50 or fewer emp.) **Reviewed Date:** April 25, 2018 **What do you like best about Thunderbird?** it is, sadly, the best one for free. Its easy to use at first, but i think they could erase some options and leave only important things on front, then they can add options for those who cares... I think they have tried to make a software too heave for what some of us need... I need it to work easily and without too much work from me, not as if i would like to do nothing, but if could be that way i know i would love it. **What do you dislike about Thunderbird?** Thunderbird is a horrible software, old design, and without many of the things you need from this kind of stuff... It has troubles to update and mails are only purchase... I know it could be better knowing a lot about it, but its hard to be able to learn when what you see is not good... i would prefer to use a different software, but it is, sadly, the best one for free **Recommendations to others considering Thunderbird:** take a time travel to 90's, i think it should be a little bit better (or much better) **What problems is Thunderbird solving and how is that benefiting you?** getting multiple mails in one window, but its hard to update, i only use it for mails without importance. Main benefit is the fact is free, then you should go for what some people with more knowledge about this things care, probably the best one for programmers and guys like those. For me, a journalist trying to do my job, its sad... ### 34.

Thunderbird - A Solid, Free Email Management Application **Rating:** 3.5/5.0 stars **Reviewed by:** Jason B. | Web Content Manager, Small-Business (50 or fewer emp.) **Reviewed Date:** December 18, 2017 **What do you like best about Thunderbird?** Anytime I can save money by not having to buy something for the solution is an advantage in my mind.

Best Email Client Around **Rating:** 5.0/5.0 stars **Reviewed by:** Ryan S. | Director of Education and Public Relations for North Dakota One Call, Public Safety, Mid-Market (51-1000 emp.) **Reviewed Date:** January 26, 2018 **What do you like best about Thunderbird?** There are so many things that are awesome about Thunderbird. I was a hardcore Outlook user for a year. About 4 years ago I switched to Thunderbird based on some recommendations. It takes a little while to get used to it when coming from outlook. However, you'll find that the features and use of add-ons can make things much easier to use. The best part about it is that it's free! **What do you dislike about Thunderbird?** I wish Thunderbird has meeting support. To explain, there are two meeting scenarios I Have issues with. I use Goto meeting frequently. Outlook has a great Goto Meeting plugin that makes integration easy between the two programs. That and scheduling a meeting with other people or when receiving a meeting invitation, the "Accept" and "Decline" don't seem to work correctly. When clicking accept, I've had it email back an entire recipient list (sometimes over 100 people) with my reply. So I have to say I haven't used that in a while because it becomes a pain when I have used it. **Recommendations to others considering Thunderbird:** Give it an honest try. Once you use it for a little while, you'll love it. It's easy to use and if you need help, there are a bunch of forums and other places to find answers. **What problems is Thunderbird solving and how is that benefiting you?** Email, calendar, and tasking.

Undoubtedly Thunderbird is the best email client! So do not think about it anymore and start enjoying the power of Thunderbird. **What problems is Thunderbird solving and how is that benefiting you?** According to the disposition of the clients, in paying or not to pay for an emailing campaign, Thunderbird turned out to be an excellent alternative of low cost, really it is not paid for the service of Thunderbird but if the clients must pay for the HTML design of the emails for your campaigns.

Thunderbird has given me a great alternative to Outlook **Rating:** 5.0/5.0 stars **Reviewed by:** Jenn L. | Digital Marketing Specialist and Consultant, Small-Business (50 or fewer emp.) **Reviewed Date:** November 28, 2017 **What do you like best about Thunderbird?** I like that Thunderbird doesn't weigh down my computer the way that Outlook does. When I need a software to actually just check email, this is my favorite since it loads quicker than Chrome does on my computer as well to check from the web. For personal use, I really like Thunderbird (even when I am using Office365 for work). It works very smoothly with my Gmail account and notifications aren't bulky and push to me quicker than they do on my phone. **What do you dislike about Thunderbird?** Functionality within Office 365 isn't complete. If your company works 100% within the Office365 environment, some key features may be missing in Thunderbird. The integration isn't seamless. **Recommendations to others considering Thunderbird:** Thunderbird is free and allows you to sync up your email from multiple accounts easily. **What problems is Thunderbird solving and how is that benefiting you?** I have to use my personal computer for work, so having this software allows me to use it while I can continually run other CPU heavy programs. ### 49. Best free tool to replace outlook **Rating:** 3.5/5.0 stars **Reviewed by:** Pradeep B. | Senior Consultant, Consulting, Small-Business (50 or fewer emp.) **Reviewed Date:** October 27, 2017 **What do you like best about Thunderbird?** Its different. Though similar to outlook, it has a different user experience which makes it more fresh. I use MS outlook both on work as well as mobile, so am pretty bored of the same experience and the same tones in both. Thunderbird gives me a break from both of them From a corporate usage perspective, costing means valuable financial resources. Money spent on software means less money spent on manpower. This is where Thunderbird chips in. It allows to send emails and attachments upto 25mb, and infact even allows to attach emails in the exact way you'd do in an outlook. Its especially helpful in small companies where Gmail/yahoo is used as primary email and companies do not invest in a full fledged email server to provide a unique branded email id to its employees, and does not contain sensitive client information which should not be stored on the cloud servers. **What do you dislike about Thunderbird?** Copying and attaching mails as attachments isnt as smooth in THunderbrd as it is in Outlook. Formatting is needed to the text coming from Word/other Microsoft office products used with it. **Recommendations to others considering Thunderbird:** Keep improving your work. Add more features and keep it trademark Mozilla. I am completely in support of thundrbird for windows/ Hallelujah **What problems is Thunderbird solving and how is that benefiting you?** It allows me to manage multiple emails at one place, easy peasy. No need to run around here and there. Also, i can filter and search easily, and store emails offline when i do not have internet around. ### 50. One of the best Email clients equivalent to Outlook **Rating:** 3.0/5.0 stars **Reviewed by:** Verified User in Internet | Small-Business (50 or fewer emp.) **Reviewed Date:** June 13, 2018 **What do you like best about Thunderbird?** Since the product comes from the likes of Mozilla, we can be sure that the product is solid.
