What is the best way, either postman or server/admin API, to add x item to bulk accounts via their email address? Is there an API call that can do this? I thought I saw one a while back, but I can no longer find it!
For example, we promised a free item to those that signed up long ago (1600 players). That would be awful to assign them 1-by-1. I'm sure an alternative is to make a coupon and email them, however this is a system we should probably setup anyway, so I'd rather do it programatically, if possible.
