I started a campaign yesterday with a smart list of about 3000 people.
Added a random sample of 4% to throttle the number of outgoing emails.
I set it to run once daily.
The smart campaign settings are "Each person can run through the flow once".
What I'm seeing is that the first day sent out about 4% of the list. The second day sent none.
I'm guessing that I need to set "Each person can run through the flow every time" but I'm concerned. I don't want people to get sent the email again for at least 2 months anyway.
If I set it to "Each person can run through the flow every time", will the person come up in the random sample again?
If not, how can I reset them in 60 days?
You need to find a way to get the records that were already sent the email to not go through again like adding smart filter for NOT WAS SENT EMAIL.
I'm not entirely sure how your campaign is setup, but that filter alone should already do the trick for the most part.
Please post your smart list and flow screenshot.
Also, there is a doc on Random Sample, please search for it and review it.
