What users are saying

1. Or, I see a notification for a message I already read and deleted.Fastmail is a great email service imo & I really like that they've (finally) updated the app from a web browser in app format to an actual app.

2. The other improvement I would like to see is the face of the Fastmail icon changed to show the date.If you have a fastmail account, this is the best way to read email on the service.

3. Great e-mail service, lousy app update... and please DO NOT jut ask me to send an e-mail with suggestions, be proactive and come up with a better UI or give users a way to revert to the old one!!!Used to be awesome but the recent UI changes have broken really basic functionality.

4. I have been using the service for years and this was the only issue I have hadThis app has a great user interface.

5. My only issue is that my Galaxy watch 4 doesn't like to sync notifications by default, but that's probably Samsung's fault.I've had Fastmail subscription for about 10 years.

6. Things moved or arranged haphazardly, you can't download attachments directly from an email anymore (you have to save it to their file service then download from there).

7. After using this for a while I'm definitely considering switching away from Gmail.Never had any issues with the app's performance, it does everything that the web interface can do, and it's been a solid experience.

8. I've been using Fastmail for years and I appreciate the newly redesigned Android app.

9. Outlook has a setting that can enable syncing such things to the device within the app.I realize a lot of effort has been put in developing this new UI but personally I find the old one was functionally way better.

10. Fastmail is the best.The App was crashing about a month ago, however, after having several discussions with support, it is likely my phone or settings within the phone.

11. Support was knowledgeable and went beyond standard information and fixes that seem the endpoint for many customer service representatives.
