Undo/Scheduled Send is one of those features that seems like it would be trivial to implement (just delay sending the message, duh!)

But delay long enough and iOS will kill your app. And if you are terminated, how do you guarantee waking up at the right time to send? There's no public API to do this.

For Big Mail I've had to get creative, ultimately relying on a cloud component.

(Apple Mail is allowed to cheat somehow, of course 🫢)

@phill the subtle pulse of color as the sent icon turns orange is…

@phill Beautiful 🤩

@phill Nice. Because of the animation I’d now expect that hovering with my mouse would pause the count down. And unpause on mouse out.

@phill can’t wait for the TestFlight!

@phill I can’t explain how excited I am for Big Mail 2.
