      Evolution vs Thunderbird
      pros, cons and recent comments
      well, I use cinnamon desktop, Thunderbird does not display 24 hour format but AM/PM for starters. Also, I use the built-in acount manager and Thunderbird does not "talk" with that as well.. Evolution does sync my CALDAV and CARDDAV from this. Thunderbird needs plugins for this and these plugins also make Thunderbird unstable (lightning). Since I like to keep things "clean", Evolution is my software of choice ATM...

      Claws Mail vs Thunderbird
      pros, cons and recent comments
      3psilon It's a good, lightweight alternative, but the UI is clunky and it misses HTML message composing. You have been warned!

      jodumont Despite the style, Claws is super fast and allow you to programs it with Perl and Python which is great for marketing automation.

      No HTML compose is the only reason I don't switch to it. We're not in 1980 anymore.

      very good alternative under linux. I can not say the same under windows since fancy plugin is very buggy.

      SeaMonkey vs Thunderbird
      pros, cons and recent comments
      SeaMonkey is both a WEB BROWSER and EMAIL CLIENT. It's the successor of Mozilla Application Suite or Netscape Communicator, resp. Further it includes also a news client program, an HTML editor (SeaMonkey Composer) and an IRC client (ChatZilla).

      More of a web browser than an email client

      Thunderbird connects with servers that use standard protocols and with servers for which a plugin was developed. ElectronMail works with ProtonMail ONLY and was specifically designed for this provider. Tutanota support is deprecated since July 2019.
