Comments about Thunderbird as an Alternative to Apple Mail
Looks like piece of crap. Intrface is like from windows 98. Rediculous UX design.
Thunderbird can do more than Apple Mail, it's stable, the 2023 update has improved the UI a lot, and I can also run it on Windows and Linux.

Most users think Thunderbird is a great Apple Mail alternative.
- Thunderbird is Free and Open Source
- Thunderbird is Privacy focused



























































It has too crowded a look to listing email. Compare the wide screen view of both. Thunderbird puts all the details on one line, apple uses multiple lines and gives whitespace between mails.
