  1. The only app on Linux needed for email is Emacs. I also use evolution, but Emacs can do it faster, way faster. Easier to write, edit, search etc.

  2. How is Thunderbird first and good for workflow?
    If you close the program by mistake bye bye workflow, you won’t get new mails or notifications. Also when you expecting a email you need to keep it open all the time or manually open it every 5 minutes to see if the mail arrived.
    To use workarounds to keep it open in systray it’s so 2003, also most wont work on Wayland.

    IMO Thunderbird is useless without a background service that gets you notified on new mails. I’,m currently using Geary, not that good but at least i get notified on new mails and can do my work.

  3. Claws Mail is NOT very good at all. I installed it on my Linux Mint system, and to begin with, the “Spam” button is greyed out (non-functional). So, looking at creating filters to filter out spam: 1) you can only create one rule; 2) when you create that rule, it doesn’t run automatically…not even on the spam message you created it for. You have to run it manually. I’m trying to replace Thunderbird, which, to keep the extensions I use every day, I have to keep an old version, before Mozilla decided that nobody needs those (some heavilly-used by many users) extensions anyways, and removed support for all of them. Well, Claws Mail is not that replacement. Still looking.

    • Claws-Mail needs an additional spam filter. There are a few possibilities available as plugins. I am using bogofilter with claws.

  4. Consider RE-Alpine for Linux/Unix, a fork from the Alpine 2.01 last issued from U of Washington years ago when Mark Crispin (creator of the IMAP server) was still with us. It is available via Source Forge ( as version 2.03, to build and compile as you wish, open source for sure.
    Yet there is a deb(easy Debian installer version) offering still out there of 2.02-3.1; safe, quick, works well, fast text email, no nonsense, I use it. I use no other.
    Another fork exists from another developer, status now unknown but it shows up in some Ubuntu packages as v2.21. I use Synaptic to lock it out. I know RE-Alpine works safely. Beware of counterfeits.

  5. Mailspring forces you to create a so-called Mailspring ID, which is a no-no for anybody who is concerned about privacy and confidentiality.

  6. Having tried Hiri, I cannot recommend it. It would not successfully connect to my Office 365 business account. While working with support, I received one email. Repeated follow up emails from me went unanswered.

  7. You left out Roundcube, but instead included Hiri in a list of “Free and open source e-mailed clients”, well at least you didn’t think “Outlook” would be a nice addition…

    • Though Hiri is not open source, still it’s worth to mention here because of the versatile list of features it offers. Yes, Roundcube is a free and open source webmail client, not desktop-based Linux email client. Outlook is a baby of Microsoft and doesn’t support Linux as usual.

      • It is not open source, thus it does not belong in a list of “free and open source” software. And come on, who in his right mind would use Office 364?

        • You are absolutely right that it’s not open source and free. Moreover, I am getting a bad review for this Linux email client Hiri. Soon I am going to replace it with another one which is effective, easy to use and free. Thanks for your suggestion.
