How to choose

01

Count your contacts

Price rises with list size. Check the price at the list size you expect in a year, not today.

02

Check the free plan's sending cap

Free plans limit contacts and monthly sends. That's fine for testing, but rarely enough for a growing list.

03

Look for automation

A welcome sequence that runs on its own is where email pays back. Check how many automations the entry plan allows.
