Hello! I set up the first email in my sequence to deliver "3 days after last email" - with the intention that it would be 3 days after the incentive email (with my opt in). I set up the 2nd email in the sequence to be 3 days after that. The subscriber is only getting the 2nd email. The 1st email is also active. Any thoughts? When I put "3 days after last email" (on the 1st sequence email) - is that being triggered after they subscribe and get the incentive email?
