Excellent, but needs time stamp

I love this app! I've recently moved across from multiple gmail accounts, to just one FastMail account that lets me have as many email addresses as I want. This service is 100% worth the money! The rules and folders are the best feature for me. I've noticed that the time that emails were sent doesn't show anywhere that I can see; this could be a big deal in some cases, and needs to be rectified.

App Let's Down a Fantastic Service

I am totally sold on Fastmail and love using it from a browser.

However, this review is for the app and it doesn't quite live up to high standard they set otherwise. My biggest problem is that the text size doesn't change when you change it in the phone settings nor can it be change within the app. For this reason, I frequently use the default Mail app for my Fastmail account.

It's a great company so I'm sure they will address this.

Great service; app needs work

I love fastmail to pieces — a brilliant service with fantastic customer support and very reasonably priced. But the app needs a little tlc; poor old iOS fastmail hasn’t seen even a maintenance update for nearly a year now. Features like tagging and mail snoozing are pretty standard in many clients these days, and indeed my desire for those features means I use a different client on iOS (and macOS for that matter). If the fastmail iOS app got some love I would switch back in a heartbeat!
