Developer pricing
Plans are sold on requests a month, not on mailboxes. Every plan includes unlimited inboxes from the API, long-polling, webhooks and usernames you choose.
What counts as a request
One HTTP call to the API is one request. Creating an inbox is a request; reading its messages is a request. A long-poll that holds open for a minute waiting for mail is still one request, not one per second — which is the main reason waiting is cheaper than polling.
Inboxes you create from the API expire on their own and never count against your plan's permanent addresses.
When the month runs long
Once the month's included requests are gone, further requests come out of credits you have bought. Credits never expire, and nothing is ever charged automatically — a test loop that runs away overnight cannot produce a bill you did not agree to. It simply stops.
| Credits | Price | Per 1,000 |
|---|---|---|
| 10,000 requests | $25 | $2.50 |
| 50,000 requests | $99 | $1.98 |
| 200,000 requests | $299 | $1.50 |
Buy them from your account. While credits are paying for your requests, every
response carries X-Credits-Remaining, so your own code can tell when it is running low.
Keeping an eye on usage
Every response carries X-RateLimit-Limit and X-RateLimit-Remaining, and
GET /v1/usage returns the same numbers on demand. In CI it is worth logging them, so a run
that starts failing near the end of the month explains itself.
Something bigger
If you need far more than the largest plan, your own sending domains, or an agreement with uptime and support commitments, tell us what you need and we'll quote it.
Questions people ask first
Is there a free tier? Yes — 100 requests a month, no card and no expiry. It is enough to wire the API into a project and watch it work. Claim it from a developer account; nothing renews, so there is nothing to cancel.
Can I cancel any time? Yes. Plans are monthly, and there's a 14-day money-back window on your first payment — see the refund policy.
What happens to credits if I cancel? Credits are attached to your account and stay there. They don't expire.
