I don’t have Apple Mail set up on my iPad because I don’t want to be distracted.
Is there a way to share User Presets between the iPad and my iPhone without using the Apple Mail app?
I don't think so. You could get a separate gmail account just for this purpose, and configure it in Mail Accounts, so you can send using it. And turn off Mail Notifications to avoid distraction.
Ok thanks, good idea or just replicate it on iPhone too 👍
