My use case might not be too common, but I use fastmail with multiple aliases and the official app is the only way for me to send emails with these different aliases.
Another reason is the lack of push notification (not sure if i'm using the right term) when using the built in gmail app for fastmail. It only gives me the option to poll every 15 minutes. The gmail app also doesn't support actions like snooze, swipe to archive etc on non-gmail accounts and I like having that in the fast mail app.

I'm doing exactly this from Android with Aquamail.
Do you have to configure the individual alias in the app? If so I can see it getting really tedious to keep it in sync with the aliases inside fastmail.
My reason: they recently rolled out message snoozing on the server side (this is normally achieved by client apps), however the native Mail app doesn't support this.
Fastmail's iOS app does support this functionality.
