The native iOS mail app is push notification enabled from FastMail; there’s no reason to not just use it.

You have to use the FastMail app if you want to send from an email alias. That's the only reason I have for not using the native iOS mail app. Please let me know if you have a workaround!

You can send email from your alias with the Mail app, I do it every day. You need to set it up manually (not use the certificate from fastmail). After you set up the email address, go to Settings -> Password and accounts -> Tap your account -> Tap you email -> tap the "Email" field and then you can add your aliases tapping the button "Add Another Email"

I'm pretty sure you can add e-mail aliases even after using the certificate from Fastmail.

(Disclaimer: this is undoubtedly true on macOS; I haven't done this sort of thing on iOS in ages.)

FWIW fastmail’s web UI is entirely built on top of JMAP. (If you’re curious you can add &debug=true to the URL in your browser to turn off compression and see all the JMAP queries the web UI makes in the inspector). So any 3rd party email clients can support all this stuff on top of JMAP in a standards complaint way if they want to. Anyone who works on native mobile email clients, please add support for aliases and snooze and all these great features via jmap!

You should just be able to add the other aliases in the settings for that account. I haven't personally used it but the option is there.

I don't see that option in the iOS Mail settings. Can you point me to it?

Edit: here it is: https://www.fastmail.com/help/clients/iphone-aliases.html I'm going to give it a try now. Thanks!

Have been using it for years, it works great!

This. Only thing I’d like is offline notes in it. Literally in the middle of the supermarket and I can’t get to my shopping list
