Let's say I have a campaign that is sending to a total of 500K contacts... Is there a way to set it up to send to 100K contacts, and then the next 1000K contacts a week later, and so on without creating 5 different campaigns? Thanks in advance...
You can create different -2 smart list and further use in Flow section with choice and wait.
Ex.. if member of smart list 1 - send email -> wait 1 week -> if member of smart list 2 - send email ->wait 1 week and so on..
You could do it would 2 smart campaigns:
and so on you could also add remove from flow steps for those that were sent the email.
