Looks good AW!
A must-have for most people, I’m sure you’ll do well out of it.
Would be nice to be able to send “auto-login” links so it’s easier for people to write a review or order a follow-up offer. Automated time-limited promo codes unique per order would be great too. “Order one of these in the next & days and claim X% off with XYZ code”. Tracked links and mail-opening track-pixels with a Report in the admin would be nice too, but we can of course use tracked Google Analytics links or equivalent.
Even better would be rules based on products ordered, like the shopping cart rules. Some of our products need replacement parts after half a year. “If customer bought 1 of X, send this template.”
Anyway, let’s stress-test this in a live environment first before taking it further!
One question, if I now install this and set to email something 7 days after the order on status Complete, will on the next cron run all previous orders up until 7 days ago get mailed? Or only starting now? I wouldn’t want 1000s of old customers to get a follow-up that’s written for more recent ones.
