very good. I hope it continues to develop for a long time.

Never going back. People use Outlook or even browser based Mail clients all the time, not caring that all their messages are stored online in plain text.

With Thunderbird / Betterbird you can have all of them offline, use PGP to encrypt them, and minimize tracking. You can block tracking images (they load in messages and sites know that you looked at them) and have way more good features.

Has a few improvements over Thunderbird, but recently started to mark all received messages in my inbox as junk. About 100 emails from different addresses

Betterbird is a drop-in replacement for Mozilla Thunderbird. Betterbird has more features, more fixed bugs, and better support than Thunderbird.

The main challenge with Mozilla Thunderbird is that, in 2020, they changed from a not-for-profit to a for-profit organization. This mean that starting in 2020, there is a very high risk that Mozilla Thunderbird will increasingly value money above you, the people. Source about Mozilla for-profit since 2020 at: •

Betterbird successfully resolved this challenge above. Because is not a for-profit organization. Also, "Betterbird is better than Thunderbird in three ways: It contains new features exclusive to Betterbird, it contains bug fixes exclusive to Betterbird, and it contains fixes that Thunderbird may ship at a later stage. Please refer to this feature table for examples." "This should give you an impression of where the project is headed."
