I received this from someone regarding another platform and I think this would be a great feature for Zeffy to have as well.

Have you ever started to purchase something online…got so far as entering your email but then LIFE happened and you forgot?

Then PING…

You got an "Abandoned Cart" email from that business and you completed your purchase!

It would be idea for Zeffy to send a similar email reminder a donor/participant to remember to finish their transaction.
