Haven't quite warmed up to it – Ziploop Review

It all sounds like a good idea. However, notifying all my rewards accounts of an email change is a LOT of time-consuming work. Also, today when I had a receipt emailed to my account from the store, the receipt transferred into my app just fine, but I got THREE identical emails from Ziploop telling me that I had received a receipt! THREE! What's up with that? I thought this was supposed to cut down on my emails. Waiting to decide whether to continue using this.
