Evolution vs Thunderbird
well, I use cinnamon desktop, Thunderbird does not display 24 hour format but AM/PM for starters. Also, I use the built-in acount manager and Thunderbird does not "talk" with that as well.. Evolution does sync my CALDAV and CARDDAV from this. Thunderbird needs plugins for this and these plugins also make Thunderbird unstable (lightning). Since I like to keep things "clean", Evolution is my software of choice ATM...Has a nice Gui, works fast and has many options. Still some functions are not intuitive. Good alternative to Thunderbird - Claws Mail is an email client (and news reader), based on GTK+, featuring Quick response Graceful, and sophisticated interface Easy configuration, intuitive...

Claws Mail vs Thunderbird
3psilon It's a good, lightweight alternative, but the UI is clunky and it misses HTML message composing. You have been warned!jodumont Despite the style, Claws is super fast and allow you to programs it with Perl and Python which is great for marketing automation.No HTML compose is the only reason I don't switch to it. We're not in 1980 anymore.very good alternative under linux. I can not say the same under windows since fancy plugin is very buggy.Much faster than thunderbird which cloaks on weak machines.Small and quick and not flooded with choices! - 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. View 168 alternatives to SeaMonkey
