What do you like best?

The email client is neat and clean visual presentation. The SPAM protection is the best with Thunderbird so I chose this product for my Email Client need. When searching an email, it responses very fast and almost accurate. If I compare it with other free products, like eM-client and MailBird, Thunderbird is ahead.

The quick filter and using of tag helps organizing and dealing with emails quickly. Review collected by and hosted on G2.com.

What do you dislike?

The working capability is good so unable to give any dislike but the looks (themes) should be added more often so user can redesign the appearance/looks as per their preference. The backup of emails or transfer to other email clients (like Microsoft Outlook) is not present nor easy. We need to have Outlook Express (Very old software) or some third party software for this conversion. The simple sharing of occasions among clients could be worth added if this component can work smoothly. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Thunderbird is good looking, with simple setup, E-mail client. It works good and in my experience can support large size emails storage with very good SPAM protection mechanism. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

It is free with lots of features. The SPAM emails are filtered at very good level. It never crashes even when my computer suddenly shutdown (like on electricity issue). Review collected by and hosted on G2.com.

What do you like best?

All the bells and whistles, for free. You can't get a better value propostion than that. I also highly value companies that respect your privacy.

It's very easy to manage 12 email addresses while also keeping everything organized. Review collected by and hosted on G2.com.

What do you dislike?

The UI could be a little bit more modern. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

I wanted a solution for the 12 email addresses that I manage. I previously used gmail, but privacy has become a bigger priority as of late, so I went looking for an alternative. I've tried all the email apps, and some of them were great, even as great as Thunderbird. But Thunderbird is free and more privacy oriented than the others.

So it solves the problem of being able to receive and send emails without my privacy being invaded. And it has the same filtering capabilities as gmail, which I really need. Review collected by and hosted on G2.com.

I think one of the more difficult things about Thunderbird is finding your way around it at first, but once you find where all of the settings and features are, it is easy to set up Review collected by and hosted on G2.com.

What do you like best?

Thunderbir allows me to have in one application all the emails that I use in my personal and work life. The email of the company where I work is in the same place as my personal life and that makes my job easier without neglecting my personal commitments.

I really like the extensions that I have been able to download that have allowed me to integrate Google Calendar and Outlook, Gloogle Keep and contacts. The option to save draft email offline and the option of local folders that allow me to have important emails available without having to be connected to the internet. Review collected by and hosted on G2.com.

What do you dislike?

After reviewing many options on the internet I chose Thunderbird as my email application, however I am slightly disappointed that the versions are improving but the extensions are becoming obsolete and with that we run the risk that many facilities are lost

The interface is very clean and easy to use, however it looks old. I gave up using Thunderbir on my smart phone because it takes a long time to sync. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

I recommend using Thunderbir as an email manager, it currently has extensions that allow you to integrate it with many applications, which will make your life easier.

The best free option you can have to save your emails offline and save time when you go to work. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Thunderbir solves me problems daily, currently in my country the internet connection is problematic, and with this program I can work, design the emails to check old emails without having to have the internet active.

To be free is a high quality program. Review collected by and hosted on G2.com.

What do you like best?

It is free, and I can sync company email up with a calendar we can all see I like that i can categorize all my emails that i send and receive from customers, it makes my job so much easier and tidier Works with multiple mail accounts Works with POP and IMAP servers Expandable via "Add-ons" -- many available Very configurable, especially with add-ons Full text indexing of emails for fast searches Available for Windows, OS X, and Linux Great plugins allow making per-month archives, set up how old mail should be kept on server and which should be already moved just to local folders that can then be backuped easily. Review collected by and hosted on G2.com.

What do you dislike?

The addons can load down the application a lot, delays, slower load times, etc I loose a lot of draft and final emails on Thunderbird I've done tests where I have searched for a sender that appears multiple times in my inbox, yet only one result is returned If I had to change something I would set up the boxes a bit differently so that I can clearly see right away what is new and what is old Review collected by and hosted on G2.com.

Recommendations to others considering the product:

If you have multiple accounts, this is an easy way to download the emails for all of them. This is a great product, and seems to be the best alternative for businesses looking for a Linux mail client based on our experience and research For private, freelance and even small business use, Thunderbird will be an easy to use mail client that is not too dissimilar in interface from major mail clients. Some email providers let you access your mail via POP3 instead of IMAP, so it isn't retained on their servers Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

I'm able to view customers pictures only making it easier to help them out I have several Google Calendars synced with Lightning My company has reaped the benefits of government grants for projects We save on licenses of MS Office, Thunderbird is multiplatform and we use it on Windows 7, 8, 10, Mac OS X and GNU o Linux because we have very heterogenous infrastructure Review collected by and hosted on G2.com.

What do you like best?

Thunderbird is an advanced e-mail client and an excellent alternative to paid solutions, with many of the same features as its counterparts at the best price. The program has the most important functions such as intelligent folders, e-mails with cards, advanced search tools, and a simple e-mail configuration wizard. It also gives you access to several add-ons that add additional features, such as a calendar, to Thunderbird. Like Gmail and Outlook, it searches for words such as "attachment" and reminds you to attach a file if you haven't done so. Thunderbird is available for Windows, Mac OS, and Linux. It's open-source and completely free. Review collected by and hosted on G2.com.

What do you dislike?

Thunderbird's biggest downside is the unstable support for the project by the developers and the very governmental updates that do not make big changes. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Using ThunderBird, I recommend it to those looking for a budget solution that will allow you to browse the mail from the system level. Review collected by and hosted on G2.com.

What do you like best?

Thunderbird permette di mantenere sotto controllo tutte le caselle di posta, sia ordinaria che pec, e grazie alle estensioni è possibile personalizzare ogni singolo aspetto ed utilità. Utilissima la funzione tramite plugin importexporttools per esportare in pdf le email selezionate in automatico su una cartella, utilissima per salvare le pec di accettazione e consegna.

Inoltre, l'export dei messaggi in mbox funziona benissimo e in maniera semplice è possibile caricare i messaggi di backup e trovare vecchie email.

Consigliato a tutti! Review collected by and hosted on G2.com.

What do you dislike?

La versione installata senza plugin è fin troppo scarna di opzioni: mancano ad esempio i controlli per il testo (evidenziatore, cambio rapido colore, ecc.) e le pec non sono supportate pienamente. Installando dei plugin si risolve il tutto, ma sarebbe opportuno integrare queste funzionalità direttamente nel software base. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

Se volete un software flessibile, capace di salvare la posta senza avere intoppi in import futuri, Thunderbird è il software giusto.

Cercando tra gli infiniti plugin disponibili si può personalizzare veramente ogni aspetto Review collected by and hosted on G2.com.

Il salvataggio massivo in pdf delle email non è più un problema per me: le email vengono trasformate in pdf in sequenza e salvate nella cartella indicata con nome uguale all'oggetto dell'email; basta inserire il codice identificativo dell'email all'inizio dell'oggetto ed automaticamente avrete i pdf ordinati pronti per l'archiviazione Review collected by and hosted on G2.com.
