      Thunderbird is brutal, emClient is clean, neat, well thought out, etc. It works with Exchange, Gmail, etc. Everything in one install. Drop in replacement for Outlook at a fraction of the price for Business.

      eM client is clean and neat, it's has more built-in functions than Thunderbird. This is a great alternative for Mac and Windows users who care about the software user interface.

      Slow on rendering most email. My version of it doesn't show well unread new message : I can't tell if it's too slow or if it just fails to display them at all.

      I'm still testing it but I like what I see. The interface. I like balance, not minimalism nor clutter. I am still using Thunderbird and have not decided yet. Also it is for personal use, therefore I need a free program with at least 3 free mailboxes.

      It works. Much less buggy. Better integration with Windows. Encryption/Signing.Works over remote desktop without losing pieces of itself. Search is crappier though.

    3. Web-browser, advanced e-mail, newsgroup and feed client, IRC chat, and HTML editing in one application. Itis built on the open source Mozilla Gecko engine, the same code which underlies Thunderbird and is the base for the Firefox browser.

      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).

      Mailspring vs Thunderbird opinions
      This alternative is disputed. Mailspring is still a legitimate alternative to Thunderbird, but it might have issues that some users think are important.

      JackVegas If you're using Windows 10 or a Mac, Postbox is hard to beat. I found myself so impressed with the trial that I had to buy the license in the end. It started out looking a lot like Thunderbird, but it really has come into its own over the past few years to the point where Thunderbird has nothing on Postbox.

      Apple Mail vs Thunderbird opinions
      Most users think Apple Mail is a great alternative to Thunderbird.
      I have used Thunderbird with IMAP for years, but the tiny font problem on Mac is now a dealbreaker, and with my decades of emails and folders, Thunderbird is flailing when fetching ail or moving folders. Apple Mail does what I need it to: manage multiple Gmail accounts, not be too slow, and let me adjust font size. The arrangement of folders/mailboxes in Apple Mail is not as intuitive as Tbird but I can deal with that.

      Mutt vs Thunderbird opinions
      Most users think Mutt is a great alternative to Thunderbird.
      Thunderbird users want a GUI mail application. Mutt is a command line mail application. They are both good and both popular, but very much apples and oranges.

    9. Delta Chat looks and feels like other popular messenger apps, but does not involve centralized control, tracking or selling you, friends, colleagues or family out to large organizations. "Privacy by Design" has never been more fun.
