How does PAYG billing work?

Mailgun offers a Pay-As-You-Go (PAYG) billing model via our Flex plan, which allows you to only pay for the messages you send in any given month with no subscription fee. Pricing is $1.00 per thousand messages sent per month.

See our other plans and pricing here.

What will I be charged on the Flex plan?

If you send 1,000 email messages or fewer in a given month while you are on the Flex plan, you will receive an invoice for $0, and there will be no balance rolled over to the next month. If you send more than 1,000 emails in a given month you will be charged $1.00 at 1,001st message sent, and $1.00 per thousand messages sent after the 1,001st message.

What will my invoice look like?

At the bottom of your invoice, you will find a Pricing Details breakdown that looks something like this:

First 1000 at $0.00 each

$0.00

Next 1 at $1.00 each $1.00
Next x,xxx at $0.001 each $x.xx


Why are you charging me $1?

In order to streamline payment processing, we charge a $1 minimum fee. At $1.00 per 1,000, $1 equates to 1,001 emails.

Will the amount roll over month to month?

You will not accrue a balance if you send less than 1,000 emails in a given month, and no balance will roll over from one month to the next month.

Is it the same for the Foundation Trial?

For new users signing up, we offer a 3-month Foundation Trial in which 5,000 emails per month are included for free. During the 3 month trial, however, you actually can send up to 6,000 emails at no cost (due to our $1 minimum for payment processing). For example, if you send 6,000 emails or less, you will be charged $0 for that month. However, if you send 6,001 emails, you will be charged the $1 minimum fee, and $1.00 per thousand emails sent over 6,001.

At the end of the 3-month trial, the account will begin using the Foundation subscription plan which costs $35 per month.
