Per my client’s request, I am changing the welcome series discount code from 20% to 15% — this code is used in our welcome series which contains 3 emails and in the pop-up on the site. I’m unsure how to go about this without disrupting the customers who are already in the flow. This is the structure:
1st email - immediate send
2nd email - wait 1 day
3rd email - wait 1 day
Any advice on how to go about updating this without changing the coupon for people who are already in the flow? There are currently 74 in the waiting cue for the 2nd email and 155 in waiting for the 3rd.
Thanks!
