Purchasing additional capacity to send more messages per month

On the first of each month at midnight Central Time, all application usage limits reset back to the free allowance of 10,000 messages. Once an application has sent 10,000 messages in a month, it will receive an error from our API and will no longer be able to send messages until the first of the next month when the allowance resets.

For high-volume applications that need to send more than 10,000 messages per month, additional capacity can be purchased from our website (10,000 for $50.00 USD, 25,000 for $115.00 USD, 50,000 for $200.00 USD, 100,000 for $300.00 USD, 500,000 for $1000.00 USD). Once an application uses its free allowance, subsequent messages will start deducting from its purchased reserve until the first of the next month. An application's purchased reserve will remain available until it has been completely used. Upgraded capacity is not transferable or refundable.

Additional message capacity can be purchased instantly through our website by viewing your specific application:

Then click "Purchase Additional Message Capacity" (you may not see this option on applications that have not been used):

You'll have the option to make a single upgrade purchase or keep the credit card on file for automatic upgrading whenever your message capacity gets low.
