An account can parse up to 5000 messages per month. This quota is large enough to satisfy most customers requirements but if you reach this limit we will offer you purchasing additional processing power for the same price as the current monthly fee. For example, if you need to process up to 10,000 emails your fee will be 2x the monthly fee.
Email processing will continue even if you reach the limit. We will always try to contact you first (usually by email) before disabling email processing in your account for the current month.
