I’ve used the Spark email app for the last year or more — very happily. The last while though it’s been using ridiculous resources on my Mac so I’ve started with Apple Mail for the first time ever. Mail won’t let me paste or use TextExpander in header fields such as Subject! 🤯

I was in exactly the same boat about a year ago. Mail isn't perfect, but it sits there humming along without gobbling up gigs of RAM, so I overlook its shortcomings.

@yorrike I'm reasonably happy with it so far, but this thing about not being able to paste into those fields or for TextExpander to successfully enter text is bizarre. Luckily I have Keyboard Maestro which will allow me to type text rather than paste. Just have to actually create (and remember) the macros.
