I set up a campaign and we are throttling our emails. We used to convert our smart list to many static lists and then put wait steps between each send.
At Summit, we talked to someone from Marketo who told us a more efficient way would be to create 1 static list and then do a random sample. So we have:
1. If random sample is 2%, send email.
2. Wait step
3. If random sample is 2%, send email...and it goes on and on.
We have our campaign set that each lead can only run through once.
We have people receiving multiple emails - is it because they are being randomly sampled over and over?
