    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.

    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.

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

    As a Firefox user, I have tried to love Thunderbird but it just can't compete with Outlook, IMHO.

    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).

    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.

    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.

    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.
