You are only billed once per customer on a specific channel per month. MAUs allow a single customer to contact you an unlimited number of times in a month on the same channel at no extra cost.
If one customer contacts you multiple times via the same channel in a month, you will only be billed for one MAU. If the same customer contacts you across two different channels in a month then you will be billed for two MAUs.
At the start of each new calendar month, MAUs are reset. For example, if Customer A contacts you for the first time on July 30, and you send them a message on August 1, they’ll be classed as one MAU for July and a separate MAU for August.
Every plan includes a fixed number of MAU credits.
We charge a flat rate of £0.20 for every additional MAU that you message. Remember that the overage charge is per MAU, not per message.
