Charged us for inactive users! and even user without emails!!!

our new provider doesn't charge by profile so we will also save time by not having to remove profiles every month to try to save on cost.

2

Continued profile creation after removal

critical overage

Even after removing Customer.io from your codebase, the system may continue creating new profiles and charging for them, leading to unexpected ongoing costs.
