What happens if you exceed the volume limits?
We will never bounce mail for exceeding volume limits. If your current usage exceeds the limit for their existing account type, at the end of the month, you will receive an email informing you, and asking you to upgrade to the account type whose volume you are currently using. Should your usage remain at that level through the following month, we will automatically upgrade you to the appropriate account type.
