We typically send to a smaller engaged list (opened or clicked in the last 90 days), and every so often we’ll open that up to last 365 – pretty standard. What if instead you could include the 365 segment on every campaign, but choose to send to a random sample of say 5%?
This would also be extremely helpful for re-engagement. We’ve inherited client accounts that have large segments of people that are worth trying to re-engage, and we end up making a large number of batches – take a random sample of 1000, exclude the main segment to exclude that sample, repeat like 20 times. It would be so much easier if we could just create the segment we want to try to engage, then include that segment on every campaign for a few months, sending to 5% or so every time.
I’m also curious if anyone has better ways of achieving these things than the methods I described?
