Great redesign and service

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).

Edit: They added iOS Sharing!!! Yay!!!

Only last suggestion: add dark mode for iOS 13??

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.

Great service, wish the app was native

Opened the app this morning to find they’re forcing me to use their preferred font instead of the system font I had selected in the previous version. I looked through the settings and it seems they’ve taken that option away. The dark mode also is custom, and isn’t True Black but instead an annoying very dark gray which makes for a brighter screen at night than is possible if they used the native UI. This app is what you get when web developers don’t actually like the platform they’re developing on, or think they can do better than the OS - it makes for a jarring experience with the rest of the phone.

They’ve also increased the amount of white space, and made the font size of the folder you’re currently viewing much larger, creating more wasted space and reducing the number of messages visible on the screen. Why not put it between the menu bar control and the search icon? I love FastMail’s service but am growing to hate the app.
