Very good

It must be great given that I’m here merely to gripe about a small thing.
Gripe: It takes way too many clicks to copy the address an email was sent to to the clipboard. I use disposable email addresses mostly (unique to each recipient, so there are hundreds) so I’m constantly needing to do this. I can see each address while scrolling through emails in a thread. but it’s:
Click to expand
tap, tap to show details (Yeah, NO, it’s not on this giant menu!??!)
(NO, at this point or the last, I can’t long tap on the address either - that works in some other apps but in this one, that gets me almost nowhere as selecting and copying is impossible or really difficult and unpredictable that way—And my recollection is it was easier back in pre- iPhone 4 days but that’s an iOS issue...) Note: Discovering through trial and error that there is no quicker way to accomplish the task takes way, way more steps than shown here!
tap for menu
Tap for more
Tap for copy

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, 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.
