Great redesign and service, but lacking iOS integrations

I’m a happy Fastmail user, and have used Gmail, Office365, Yahoo Mail, and a self-hosted solution in the past to handle my email. Out of all the options, Fastmail made the most sense, even after paying their reasonable fees. Haven’t had more than maybe a hour worth of downtime, and their support is actually useful. Their product is great and is not only super fast, but also secure. I’ve done a great deal of research into their backend/operations, and they are dedicated to security in a multitude of ways, and interested in the “next wave” of technologies for email. The only suggestion I have is for integration for iOS sharing (ex: If I want to share a PDF I first have to save to iCloud then upload that document from iCloud manually into email, whereas with Gmail you can use the sharing extension with one tap).

New Logo

I have been a Fastmail user for many years and I like it for the most part. However although the new logo may be “ fun”, the top white section does not make it look like an envelope. In my opinion a slight modernization of the previously well recognized logo would have being welcomed. I would rather see FM add more features and functionality which is needed and described elsewhere....and please touch up the new logo. It is hard to recognize as I think you intended.

Great service, needs a more modern UX

Fastmail is great, and I’ve had no issues that I can recall with the service itself. The settings and options are a little too nested in some cases which makes it a bit cumbersome to change things when needed; albeit not often. The features are great; haven’t found anything I “missed” from my previous email services.

In regards to the interface - I’d like to see a more modern take. The app icon was updated today for the 20th anniversary but now it just doesn’t “fit” with the UX - at all. The design is straight forward, but feels dull. I do love the minimalist feel but feel like its a bit behind. Especially since it seems like the app is just wrapping the web interface.
