We recently did an email campaign where the smart campaign "flow" was
Send Email 1 (middle data line in diagram below)
Wait 4 days
Send email 2 to non-responders. (upper data line in diagram below)
Does Marketo gauge the non-responders from Sent or delivered emails?
Where does the discrepancy arise from between the opened emails in the first mail and the sent emails in the second mail?
Thank you for your feedback.
