Kaiten Mail (Free)

★★★★★ useful and solid mail client still I keep using K9 which is quite similar and has everything I need. Both, K9 and Kaiten (K10) are great apps

★★★★★ Excellent Mail App This is the best mail app I've had that gives me offline access to my inbox and good for threaded messages. I give it four stars.

★★★★★ Great email client. Very well done email client, one of better email clients I've used, well worth trying, thanks to the developers.

★★☆☆☆ This app has cost me friendships and opportunities. I loved the design. I loved the staunch cold-heartedness of it. Like fake Le Corbusier architecture. It worked. It had a clear structure of its usage flow. Kaiten Mail was perfect. But for one of my IMAP accounts it one day stopped sending messages. I never noticed because the composed mail was send without any issues - AT LEAST THE UI SHOWED SO. I was puzzled that the mails didn't show up on the server when accessed from my computer but I thought nothing of it. Not until I tried forwarding an email I just received I noticed something was amiss. My friend, sitting next to me didn't receive the forward. I sent it four times until giving up and sending it by the Share-> command and then sharing to gmail. That worked ! So WTF , I go back to the app and go through the folder view and I notice that there are 8 unsent mails in the OUTBOX - the oldest of them from November, 4 months ago ! I lost two big opportunities in my life to this crapp. I have deleted it and I am now using the fork kalled K-9. It looks identical and it hasn't exhibited any of the annoying problems of this app.
