I have a list of about 6,000 leads, and I want to send an email to these clients in batches, over time. I'd like to send to about 500 contacts per day. I've set up a batch campaign with the smart list criteria to include leads who are part of a specific list. I update that list with new leads daily, and this feeds my recurring batch campaign.
Is there a better way to stagger the send so I don't have to update the list manually, each day, to achieve a small send every weekday morning?
