We have a 3,000 contacts list and wants to delivery a single campaign email in 5 phases of aprox. 600 each. What is the best way to do it in Hubspot?
I'm considering in creating 5 lists with 600 each depending on the first letter of email (for example the first list is composed with emails that begins with a, b, c, d ... )
This is the best sollution I found until now but it looks a bit dirty, dont looks the best solution.
