I had an update to a digital product last week. Since I didn't know how to reactivate all the downloads at once, I reset them, one by one (I had over 50 instances). Then, I sent an email notification to all those who had purchased it. That is when things went odd.

Since I did reset the downloads manually, I was able to see who had purchased it (I have a pretty regular crowd). When I sent the notification, it said it sent to 37 recipients. I could see a handful of bad emails but that was about 15, which seemed a little high.

In addition, after I had mentioned the update in my forum, those who had purchased it never got the notification. Then, some who got a notification, emailed me saying they never purchased it.

So I am confused as to how the recipients are "selected" since it didn't seem to match.

I have another update now to do and I am unsure how to notify the customers or whether I am doing it right or not. Is there a particular setting I should be checking or changing?

Thanks.
