Great app. Definitely worth the price. Plenty of options. Every one in a while I will try another email app but always come back to Nine. I use it every day all day long. Update 1/12/25: still working and still using it, but lowering my recommendation as it appears this app has been abandoned and there have been no new updates or features over the past year. Kind of disappointed as it has been one of my go-to apps but other apps are starting to look better.

Goodbye after 10+ years. No longer a fan. App is no longer maintained and features are breaking across the board. Active Sync no longer works as it should. Have to open app refresh to get new emails etc. REFUSE to pay for a monthly fee to have emails stored through a 3rd Party server. Highly Insecure!! Moved on to Outlook app as it is integrated seamlessly with 365.

I have a complaint that led to more complaints. Accidentally moved five emails on an IMAP account to Trash. There's no way to move them back. Tried to open the help doc, and it was about Exchange. Tried to report it as a problem, and Nine generates a problem log...which you can export, I guess? Per the prompting it should have turned into an email. It did not. Finally I tried to share feedback, which opened an app picker? Very strange behavior from what was one of my favorite Android apps.
