Lots of folks might like to remember to follow up on specific emails. I know my life is full of email that, honestly, I don’t care much about, but really need to get back to at a certain point. Or that one email that needs a return reply but gets forgotten in the deluge of other, equally important emails during the day.
Unfortunately, there’s no “official” way to do this in Mail. There should be, of course, but there isn’t. Outlook has this functionality within a contextual menu, and there is a service for Gmail that lets you do something similar, but Apple’s Mail does not.
Luckily with a little ingenuity, we can get around this missing feature in Mail..
