Claws is a 25-year-old email client that is still getting updates. The look is a bit old-fashioned, but it does have a reasonable dark mode, and is good at managing IMAP messages and folders.
Claws Mail Features
- Great dark mode (looking at you Kmail)
- Easy to configure multiple IMAP mailboxes
- A joy to view HTML mail in text (still with working URLs)
- Can drag messages from one IMAP mailbox to a different IMAP mailbox
- Kmail could do this but Geary could not
- Can configure toolbars extensively
- For example creating an archive button
- Up-to-date apt repositories
sudo apt install claws-mail
Claws Mail Antifeatures
- No Universal Inbox concept
- Have a bit of configuring to do to get everything working (but quite extensible)
- No easy way to toggle between text and html email formats.
- Weak calendar integration (viewing as a calendar, though appointments are supported)
