Great email app. Normal traditional interface. A little on the slow side but stable and competent. Best I've found. Added: On new tablet with Android 7.0, syncing self disables. I can toggle it back to on using the global network setting for background sync, but it wil be disabled again in an hour more or less.

Good email client, but there is few very uncomfortable moments. 1) When I try to star message in list(star button placed most right side), then it's like roulette - will it star message or will it activate hidden scrollbar and fling somewhere me in a list. 2) Message grouping is not good enough. Many messages that correctly grouped by gmail will not be grouped by k9

The UX is pretty bad but I use it because it supposedly is privacy-friendly. But the app doesn't fetch my messages! I've a yandex account but new messages don't show up, even when I refresh over and over again. Edit: not reliable at all as it rarely notifies me of new emails no matter what email service. Very frustrating so will have to ditch it.

I installed K-9 Mail because I needed the encryption capability which works great. The only negative comment I have is that it doesn't seem to save the email your working on when your phone shuts down due to low battery. The email I was working on was enabled for encrypted setting, don't know if that had anything to do with it ?

How the Mighty Have Fallen - used to be my go-to app for email on all my Android devices, but since I upgraded to an S8+, the app no longer syncs my mail. Checked the dev forums, this issue was reported but the devs closed the ticket as "will not fix," so the app is essentially useless to me now. Good job shooting yourselves in the foot.

* Good email app with some bugs. I use it every day. * Sometimes it hides unread emails in unified inbox for weeks and then, all of a sudden they show up again. * New bug: Forgets different email folders of my gmx mailbox from time to time. This results in showing up unread emails from that folders in unified inbox as if they were new. Refreshing folder list of affected email account does not help.

I've been using K-9 Mail since my first Android devices (HTC EVO 4G and Acer Iconia 500 tablet), and it's only gotten better over the years. I'm currrently using it on my Moto G5S Plus phone and Samsung Galaxy Note 10.1 2014 Edition tablet. I recently tried it on my ChromeBook, but was very disappointed in how it was formatted/displayed on the larger screen. I then discoverd that I can just run the full version of Thunderbird via Crostini on my ChromeBook, but this is still my favorite Android email app. It's reliable, stable, easy to navigate, and just plain works.

This eMail app is open source and still under construction. Open Source is the way to go with any app like this for security reasons. It works great. It's a little different then most but there is plenty of documentation on GetHub. Super fast and highly configurable. I would not suggest this email app for a novice although basic configuration is documented and most of it is preconfigured. Just add your Gmail account and you should be ok. I however suggest you go to GetHub and read through the folder class information. Works super fast. Way faster and smaller then Gmail or your native email client. Once you get it working you can bloat stop Gmail and native. No stinking ads which you know that's not the case for others. Small in size over other email clients. Reliable and so configurable. Great job open source team. Still has some small growing pains but they are still working on it. Again I do not suggest it for a novice but it can be done. Ron @ Memphis, Tennessee USA

On Android 8 there's every other time "Syncing Disabled" (though manual sync works) makes app unreliable and by that almost unusable. @dev: It's not your bloody job to decide when to sync. Just _try_ it *each*and*every*time* you're supposed to sync.

I have used this for several years and currently have it installed on my phone and Kindle with 9 email accounts all feeding into the unified inbox. Even though many reviews mention trouble with syncing, once you have all the settings cooperating with each other everything works just fine. My only complaint is that encrypted password is not supported.

For some reasons, on my Pixel 2XL Android Pie, K9 is always on the second or third battery drain. It feels like it's always draining battery. FYI I have not optimized the app so that I can receive email push. Same thing for Gmail app but no such battery drain for Gmail app or other non-optimized apps I have.

One star off for the idiotic, ugly new logo icon. Old review : This app is not perfect, but how come a basically volunteer effort produces a much better email app than multibillion dollar corporations can? Gmail, etc, be ashamed...

I love K-9 💘 It has all the options I need and I can set it up to work and display exactly how I want. Only thing it's missing is a scheduling/reminder feature. Recent updates have made it work smoothly and flawlessly!

5 star reduced to 1 star. It was bad enough when Ctrl-A would open the address book rather than Select All. Now Ctrl-C is broken. Rather than Copy, it pops up some stupid dialog about encryption. What's next? Will Ctrl-X summon Wolverine and Ctrl-V vacuum my floor? Tried using the requested Bug Report site but that was just a jumble of developer speak and not at ALL end-user friendly.

It's a shame. First Kaiten does a bunk, then K9 trashes its icon and the dev(s) refuse(s) to listen. I stuck with it for months but along with the synch problem I eventually trashed it for Bluemail. It's not my K9 but you cannot continue to insult folks with that flippin' icon. You are asked to submit bug reports rather than one star reviews, fair enough, but the carp icon is not a bug and no one's going to convince me that the dev(s) are not aware of the hostility to that icon so why bother? On top of that, the Play Store entry uses the good ole K9 dog icon? It's dishonest.

Was working great for over 1yr. Now it is crashing every time I open it. My main biz email I can't even get the polling on sent items. Now I have wasted so much time on it I have gone mad. No settings change. Same from the beginning. Uninstalling now. And maybe retry.

This is a good, but not great, email app. The fact that it's open source AND free is why I use it. UPDATE: Oh hell no! It's eating emails... Basically it doesn't sync properly. Now I'm afraid how much could be lost due to it.

What a needed email life saver for Oreo Go! Android 8.0.1 data hog needs are so extreme that nothing works when there is little signal, and email is only possible with city broadband.

Best free email app. I have recently come back to K9 after using a paid app. I was running out of storage so I reluctantly ditched A***mail for something less bloated. I reluctantly installed K9, remembering how buggy it was 3 or 4 years ago. Wow, what a surprise! Ok, it still doesn't look that great, but it's super fast and so far syncs reliably. And it's only 2.5 mb in size!

I love this email app for so many reasons. It's flexible in options and aesthetics is the best. However, the for the past two phones and operating systems, its polling function is completely unreliable. There seems to be no rhyme or reason to polling to randomly becoming disabled, then showing it's working again, without making any changes to settings. Very aggravating. Too bad. Hope they get it fixed once and for all.
