Automating this can be dangerous, so be careful if you setup auto sends like this.
- use Program Status to suppress Registered
- use Was Sent Email AND Not Clicked in Email to keep sending to people. Or, if they do not have an interest, use that to kick out people.
- Perhaps stop inviting everyone and focus on the most likely to show up and invite once.
Thanks for the suggestions Josh! I'll definitely work on using the Program Status, in combination with Was Sent + Not Clicked, to suppress people. Appreciate the feedback.
