John FastmanNot the prettiest, but it's open source (trustworthy), free, privacy-respecting and very functional. My go-to Android email client. I cannot hesitate less in recommending it.
4Online_Purchases1Deletes e-mail from the server even when underground in NYC subway. Makes life so easy to delete e-mails while on the train When surfacing, K-9 syncs with the server and POOF....those unwanted e-mails are gone from the server.

It runs on Linux and you still have content if you are offline.
2This would be the best alternative, except that it requires the Gnome desktop, so users of other desktop environments need to look elsewhere.
-1I've found it better than thunderbird and it can work with exchange just with one free plugin

Not enough functionality. No smart attachment feature, no quick sort by address or flags or attachments etc. Not really a business email client

PaulSince Thunderbird is still bloated and overcomplicated for me on Linux, I'm using Mailspring for the moment. It's good, the interface is nice and it has plenty of features.
0Speed of work, good connection to the mail server, speed search.
0Beautiful theme options with custom designed themes available. I tried thunderbird a few times but always came back to mailspring. I LOVE the "views" feature that shows you how many times an email was opened and if it was forwarded by the recipient!

Comments about Thunderbird as an Alternative to Microsoft Outlook
Despite its age, Thunderbird remains the most fully featured email client out there. Various add-ons can extend its functionality, it (now) has a built in calendar and, unlike Outlook, it's free, open source and respects your privacy.
The interface is just impossible for many people to use.
I remember when I first used Thunderbird, many years ago, as I'd rather have a single interface for productivity. But the interface through me off and I never got on with the editor. Coming back to it now, it's fresher and smoother. Absolutely love it. In my opinion this is the only true alternative to Outlook. Then there's the bonus of extensions to further enhance it. Though, I'd like to see further improvements to the calendar integration.
