How do I go about asking direct questions regarding my webpages? Should I make a new contact list segment and email them the questions I need answered and then run an AB on the rest of the list, excluding the ones I asked directly? I think that overlapping the two segments would skew the results somehow. I use SendPulse for email marketing and this is going to be the first AB of my own so I'm a little lost here. Could you possibly elaborate on this? Thanks in advance.
