Lightweight email client

I am looking for an open source and lightweight email client which would support most of the popular email providers - gmail, hotmail, yahoo, proton, tutanota etc.

I have been using thunderbird for a while but it lately it has started crashing so I am looking for an alternative.

Which is your favorite email client? Open Source is a must.


What desktop environment are you using? All three of the official desktop editions come with a Free & Open Source email client.

  • In KDE Plasma, there’s KMail.
  • In GNOME and XFCE, there’s Evolution.
  • The Deepin Community Edition has Deepin Mail — it’s qt-based, so it should also be usable in Plasma and the LXQt Community Edition.

Other notable standalone GUI email clients are…

  • claws-mail (Extra repository)
  • pantheon-mail (Community repository)
  • sylpheed (AUR)

The AUR has many others still, including some Electron-based apps.

I just use gmail. Easy to “install” and “backup” Works on the phone and PC.

Switch to a blank profile in Thunderbird and see if the problem persists.
Also check journal for the crash.

KMail uses Akonadi which pulls a mysql server. That is seriously not lightweight.

Years ago I threw away email clients in favor of webmail.

pamac search --no-aur 'mail client'

should give a couple of options from the repo - geary is an option

you could dive into custom packaged from AUR if fell so inclined.

Can’t get much lighter than neomutt.

yes, looking into neomutt now, the scary thing is the terminal-only :slight_smile:

Could it be due to some extension you installed? I ask because I’ve been using Thunderbird for many years and the last time it crashed was over a year ago.

no, got no addons. Precisely, it just freezes once starts compacting folders and I even cannot kill the thunderbird process I am only left with rebooting

I used Bluemail for a while on my Netflix lappy, with good success. But then I just switched to webmail.

Bluemail is available to download and install.

Another option is Betterbird, Tbird on steroids they say.
It is also available to click and download.
