Review from A Google User
*EDIT!! Moderately new bug!!!!!* Usually LOVE this app - ALL I use, for MANY years ... but major problem with last update!! Outgoing emails will NOT send unless I'm on wifi (3G and 4G working fine, but emails won't sent, get stuck in outbox until wifi goes on (getting notification saying problem sending this email). Usually goes out perfectly fine once on wifi. This is a NEW problem!! ****I'm hoping the makers will see this review and fix this*** PLEASE!!??
K-9 Mail is having trouble when OpenVPN connect is activated. All other apps and web sites work fine. Even when the VPN is then disconnected on LTE the problem persists. Moving next back to WiFi the problem still persists as well. Only a reboot of the phone seems to help.
Actually, it is a very good email app. The new icon totally sucks and the main developer seems to be completely deaf to users feedback about it. Don't be fooled by the icons you see on the Google play page for k9. It isn't showing the new icon. Even if the old icon doesn't come back, the icon needs a different look from what it is now.
Been using K-9 Mail on my phones since my first Android. Brilliant email app, does everything I need flawlessly. Have to agree with all the other users complaining about the new icon though... it is truly truly awful (Sorry to the dev who designed it!). Any chance we can go back to the old, better-looking icon? Other than that, 5/5, would highly recommend (and often do).
This has been my goto app for mail. Preferred and works well (used to). Unfortunately it uses the less secure (not insecure) CRAM-MD5 for encrypted ssl/tls/starttls. Many providers (including gmail/office 365) and secured mail servers are dropping support for this. So to connect you have to change to unsecured password (plain). Developers are aware of it (just google: k9 CRAM-MD5 can't connect - lots of talk since 2015 but no resolve. This is a free app with an amazing job being done by volunteers. However until it works with more standard options (CRAM-MD5 was in the day) we have to switch..... Which is Sooooo annoying.☹️😒 But nessecary :/ - i am going to keep a test account on this app just to keep trying every month. If it gets fixed, back to 5 star! ☹️
I've been using this app for years, always steadily improving upon an already great app.... but what the heck is with the new icon?! Please, I join with many in asking "Please switch back to the old one!" [Edit] Still a great app, but the icon still hasn't been changed back. Looks like something K-9 actually threw up. When people complain about an icon enough that some are considering uninstalling what does that tell you? lol
This is a good clean mail client with no ads and no unnecessary perms. HOWEVER, it appears to have a major functional deficiency. It seems that it is poorly integrated with contacts and it cannot acquire/learn new addresses that are directly entered into the "to" field of a new email or email reply. It neither stores them in a local internal address book nor offers to add them to contacts. This is a very undesirable behaviour / deficiency. The app also appears to lack any mechanism for managing spam, i.e.,way to add addresses to a spam filter. There is also a problem with the way it parses and delimits manually entered email addresses.
