Help: Question about A/B testing in a multiple email drip with the ability to remove a lead during the test Hey all,This campaign has a lot of moving parts so I want to make sure everything will go as planned.We're doing a drip sales campaign containing 7 emails to a list of contacts and would like to A/B test the titles.I'm having the campaign separate people into two lists (rather than using "Random Sample" in the Send Email condition) because some of these emails are in response to the one that came before it (RE:blahblahblah), so the title would need to match the previous one that the person received, and if I do the random sample each time on the send, a person who received email 1-A may receive email 2-B and have a confusing email title.To get this done, I have created a smart campaign which does the following for everyone that is a member of a specific salesforce campaign:Add to list A & B (Random sample of 50% to each)Send Email (If member of list A, send email 1-A) (If member of list B, send email 1-B)Wait until 8AM two days laterSend Email (If member of list A, send email 2-A)
