The client gave what seemed like simple instructions for an 8-email engagement program (16 possible emails in total, each having a re-send if no action taken):
" emails delivered in sequence, once per week. If person clicks, they receive the next email the following day."
After days of puzzling over how best to implement this (including reading every variable-cadence discussion I could find, including this, this, this, this, this, and this; Josh and Edward's excellent related presentations; and Kristen's whisperer tips), I'm still at a loss.
The combination of conditional re-sends (those who don't click on 1a get 1b, etc.) and a cadence that can swing back and forth depending on actions taken has me stumped. If the community has ideas on how to achieve this, I would very much welcome any/all advice.
