Developer pricing
Start free with no card. After that, pay only for the inboxes you create: $0.01 each from a balance you top up from $5. No subscription, and nothing is ever charged automatically.
What you pay for
One thing: creating an inbox, at $0.01 each once your free
250 requests for the month are used. Listing messages, reading one, waiting for mail
with ?wait=, pulling out a verification code, webhooks and domains are all free. A signup
test is one inbox, so it costs $0.01.
How the balance works
Top up from $5, any amount you like, from your account. The
balance never expires and nothing is ever charged automatically: a test loop that runs
away overnight cannot produce a bill you did not agree to. When the balance is empty, creating inboxes
stops with insufficient_balance, and inboxes you already have keep working.
Keeping an eye on usage
Every response carries X-RateLimit-Limit and X-RateLimit-Remaining for the free
requests, and X-Balance-Cents once the balance is paying. 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 — 250 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.
Is there a subscription to cancel? No. You only ever pay for a top-up you chose, so there is nothing to cancel and nothing renews.
Does the balance expire? No. It stays on your account until you use it.
