The number of unique customers you message per month. Example: Susan joins and uses your website. You have hundreds of other customers using your website but you only send Susan messages this month. Susan is your one active customer on Lifecycle for that month.
We'll email you when your account is nearing it's limit. If you hit the limit, we'll charge your account $50 for every additional 100 SMS messages, or active users for the current billing period.
