If you want to stick to open-source options, Evolution, and Thunderbird are still the best bet, no matter what.

In either case, if you want a change and have had enough with usual email clients, you should try the ones you’ve never tested and then make a decision.

Do you use desktop email clients or prefer the web browser? If you do, which is the best email client for Linux in your opinion?
