Cowliss next to the platforms you know
Both bills at any contact count, and what each platform does, row by row. Change the assumption to match how you send.
Cowliss runs every product in one organization on one bill, priced at 4 emails, 10 events and 1 automation run per contact a month; included usage comes off first. Where a platform needs a separate account per product, its price is counted once per product; where products share an account, their contacts add up.
