go back to paid for app model rather than subscription model!
totally absurd to take payment for an app then ignore upgrade suggestions for over 4 years while you work on a subscription based model which incorporates some of these features (themes) but to remove other features that were already paid for in the original purchase is ridiculous

I payed for this app. I shouldn't be getting banners asking for a subscription.

The black theme is awesome on the OLED screen, but if you choose to make gray letters it doesn’t work, on a black theme you have to put white letters.
Thanks.

More modern notification sounds.
Better email signature options.
Better spellcheck system/option.

When discuss become too long, find new attachments very hard or impossible

When looking at the email with a long thread of previous email history, this thread is often not collapsed and it takes a few seconds to scroll it all down. Also the attachments are located below the thread, so it’s very easy to miss attachments

I do not want premium, yet the icon persists. Please remove.

It is taking up screen space. It’s better if that is a one time notification, and users can find Premium in settings if they want

Why this subscription thing? One time payment would have been fine. I hate subscriptions - endless payments. I like your app but will know choose another ....

It was inevitable you'd develop a paid version, but yanking back features from established users is a terrible idea. Proposing new spiffy features for $$ is fair (Dark Mode? Rules? Bullet proof spam filters?). But please don't screw your loyal user base. Airmail is better than iOS Mail but not so much better I won't jump to avoid annoying ads or feeling betrayed.

Great that you restored push to those of us who had paid for the app before. The annoying green subscription button that hangs over my inbox, should be removed.

You do the last upgrade and you get this annoying pop up without any clue how to disable it
What are doing at airmail?

More complications would be nice for these watch faces

Automatic dark mode (ios13)

As above, include Brave browser in default browser list.

I find that I have a lot of emails from the same couple of addresses (say, a listserve that I belong to), I want to delete all the old messages from years ago, but a couple of them are flagged. People want to mass delete emails, but not flagged ones. It should warn you or let you choose your action if trying to delete flagged emails

Is there a way to track link opens? For example, if I email 3 links, I’d like to know if they were clicked. Also, if I email a pic or pdf attachment? Thanks!‬
