### "Thunderbird, top rapporto Prezzo/Prestazioni"

December 6, 2022

5.0

Pros

Soluzione free ma con potenzialità paragonabili a suite commerciali, aggiornamenti continui e plugin quasi per ogni esigenza lo rendono a mio avviso un software indispensabile in azienda.

Cons

Nulla da segnalare, il software è assolutamente perfetto così com'è.

Honestly, nothing that I can think of right now.

### "Email Use"

July 8, 2022

5.0

very good. easy to set up, and use and full of value and features needed to operate.

Pros

A great way to use an email system that is very low cost and has the features and benfits you will need for many small business applications

Cons

It has the ability to improve with more app and IT developers getting involved with new ideas, as these people basically work on this system and bring new items and ideas to the table..

### "Top Notch"

April 25, 2022

5.0

Pros

In a word, everything! I use this software exclusively to check email from multiple accounts in addition to a calendar extension for all my appointments. I could probably live without it, but I have no plans of giving it up!

Cons

Absolutely nothing to complain about. Get it, use it, love it!

### "A great email manager for everyone"

October 18, 2023

4.0

I've benn using Thunderbird for several years and have had an overall positive experience with the software. While there are some limitations, the platform's overall stability and features make it a solid choice for those looking for a reliable email client.

Pros

Thunderbird is certainly easy to use and well-designed. The initial setup is simple and organizing emails via folders is intuitive, making it easy to manage multiple accounts.

Cons

Sometimes syncing with some email services can be slow, especially with accounts that receive a high volume of emails. Additionally, the visual appearance of the interface could be improved, since it appears slightly old compared to some newer competitors.

April 22, 2022

5.0

Pros

The fact that it is free and just works. Lots of plugins to add functionality.

Cons

Uses a lot of RAM. Isn't web based (but it doesn't need to be). Wish I could back up my profile and keep that in the cloud.

### "The most popular free email client"

November 14, 2022

3.0

Pros

If I compare with other free email clients, thunderbird of course one of the best option.As an open source software, you will not have major issue with security and privacy, you can count on their community.Thunderbird also has many great add-ons, if you combine thunderbird built in features with some add-ons, in terms of features, thunderbird is able to compete with other paid software.

Cons

I've tried so hard to make thunderbird as my favorit email client, but unfortunately back then, due to lack of update and outdated user interface, i have to make a switch to paid email client.

January 12, 2023

Pros

Thunderbird is really easy to use and install. It supports all the mail types and can be configured easily. Furthermore, it supports more than one email which can be quite interesting to manage multiple email inboxes at one place!

Cons

Sometimes, the notifications are delayed or requires manual refresh to get new mails.

### "Outdated interface and clunky performance, but is a secure and feature-rich free option"

December 22, 2021

3.0

Go with Outlook or Gmail if these options are available to you.

Pros

It has a variety of extensions and options for customizing your email experience. It is a great free option for keeping all your email accounts in one place.

Cons

The UI is outdated and looks like 15-year old software. Performance is also clunky and setup can be cumbersome for those without a decent amount of experience. An inexperienced user could easily overcrowd their setup and degrade their experience without better guidance.

January 21, 2023

Thunderbird ist ein kostenloses Programm, welches dem privaten Nutzer sicherlich gefallen dürfte.Wir hatten das Problem, das alle Mails im Posteingang am nächsten Tag gelöscht waren. Woran das lag konnten wir nicht ermitteln.

Pros

Kostenloses E-Mail Programm mit, leider einigen Problemen

Cons

Posteingang plötzlich leer. Alle E-Mails gelöscht.

### "The open source email client we deserve! "

August 25, 2021

4.0

Thunderbird is great for a free and open source option, I feel like it needs some touches here and there and new features, but working with it every day is perfect.

Pros

Thunderbird is a fast and reliable program, supports a lot of email accounts without paying a single cent. Includes RSS support, and the set-up is easy as can be, I managed to set up my email account just in a few minutes. The best feature are the tabs, you can open many of them and read multiple emails. Being a freelance graphic designer I need to talk with a lot of clients, and sometimes I don't even use the same emails accounts for everyone, so Thunderbird is really helpful with it, it's really easy to change from one account to the another.

Cons

Some basic features, (like minimizing when pressing close button) I needed were only available installing extensions (third-party plugins). Kind of old interface as well.
