@LittleRavenFiberArts I hear your frustration! Please know, however, that several other things can contribute to this problem, the main one being that buyers don't always keep the email address on their Etsy account current, or they've input an email address that they don't check very often. So of course they won't see the Etsy email with the download link in these cases.
Another potential problem is if they purchase the pattern as a guest (i.e. without being signed in) -- for some reason, a lot of the emails for those guest purchases aren't received. I don't know if it's because there's no email verification on those orders, or what, but it's something I've noticed in my shop.
Finally, another possible pitfall is when buyers sign into Etsy using Apple, Google or FaceBook credentials, even though they have a regular Etsy account, too. It depends if the email address associated with these other accounts is valid or not, or is one that the buyer is looking at to receive their Etsy emails. I don't completely understand how this works, and couldn't get any further info from Etsy unfortunately. (The rep didn't even understand my question!) But it's something I've learned about from customers who had issues when purchasing downloads after signing in with an alternate account.
