Thunderbird is a free and open-source email client, calendar, contacts, tasks, chat, and newsfeed platform. It's fast, customizable and packed with great features!

Thunderbird worked just fine, but the UI was very rough and there's no real AppleScript dictionary. If you don't mind the looks and you just want email to work, sure it's ok.

It does really feel like a web browser, which I feel a mail client isn't.

The best mail manager by far. It supports all kinds of accounts, including Gmail, and with each new version, it improves even more... Totally recommended and essential.

I really gave Outlook and Apple Mail a shot but in the end I found Thunderbird to be exactly what I needed and have been using it ever since... Two more selling points were customization that can be done through addons/themes/css, and the Mozilla name since I'm a user of Firefox since forever ago.

The new “Supernova” version 115 is really good. And in some respects better than Postbox. So if you're looking for a good e-mail client on the Mac, and one that's free too, don't forget to look at Thunderbird.

I have just installed mozilla thunderbird 115 version and seems to be working well especially the search function which outlook sucks at on mac. Apple Mail is good but attachment handling sucks bug time.

Thunderbird is a powerful and versatile email client suitable for Mac users who need a feature-rich, customizable, and privacy-focused solution without any cost. Its open-source nature and large community contribute to its continuous development and improvement. While its user interface might appear slightly dated compared to more modern clients, its extensive features and customization capabilities make it a compelling choice for users who want a robust and adaptable email management experience.
