Terms of service

1. Who these terms are with

Pony is operated by [LEGAL ENTITY NAME], registered in [JURISDICTION] at [REGISTERED ADDRESS] (“we”, “us”). Notices to us go to [LEGAL CONTACT EMAIL].

They are with you: the person or organisation that pays for a plan, and anyone acting for you. If an agent, script or employee buys or sends on your behalf, you are bound by what it does. We have no way to tell an agent from the person who deployed it, and we do not try.

2. What the service is

A transactional email API, an SMTP relay, delivery event webhooks, message logs, and the dashboard that reads them. It is for mail a recipient asked you for. What may and may not be sent is set out in the acceptable use policy, which forms part of these terms.

We add and remove capability as the product develops. A plan you have already bought keeps the volume and window it was sold with.

3. Your account is a key

An account is created when an x402 payment settles. There is no sign-up form, no password, no email address on file and no identity check.

• Anyone presenting your API key has full control of your account, including the ability to send mail that is attributed to you. Treat it as the credential it is.
• A lost key cannot be recovered. We hold no email address, no password and no name, so there is nothing we could check to establish that an account is yours. We cannot restore access. An account whose key is gone is gone, and the plan it paid for goes with it. Store the key the moment a purchase returns it, and keep a second live key so that revoking a leaked one is never your last move.
• You are responsible for everything done with your key, including by an agent you deployed and including after it leaks.

4. Payment

Plans are sold for a fixed price in USDC, quoted by us and paid over the x402 protocol on the network named in the quote. A payment is verified against our own price, never against the amount a caller claims to be paying.

• A plan is a fixed number of sends over a fixed window. Nothing auto-renews, and there is no overage charge: when the volume or the window runs out, the next call answers with a fresh quote you are free to ignore.
• Purchases are idempotent on the payer address and the nonce inside the authorization you signed, so a retried request does not charge twice. A new authorization is a new purchase.
• Settlement is final and cannot be reversed by anyone. The refunds page explains what that means and when we will consider sending money back.
• Prices exclude any tax that may apply where you are. Where we are required to charge or account for tax, we will say so before you pay.

5. Sending, identities and limits

A purchase provisions a sending identity on a subdomain we control, carrying a volume ceiling, so that a first send needs no DNS record. Volume beyond that ceiling requires a domain you own and verify. Ceilings, complaint-rate and bounce-rate thresholds and daily caps are enforced automatically, and are described in the acceptable use policy.

You keep every right in the content you send. You give us permission to transmit, store and log it for as long as the plan’s retention window states, which is what makes the log and the replay in the dashboard possible.

6. Suspension and termination

We may suspend an identity, revoke a key, refuse purchases from a payer address, or end an account where the acceptable use policy is breached, where a sender is damaging delivery for others, or where the law requires it. Where mail is going out and doing damage, we act first and explain afterwards.

You end the relationship by not buying again. Nothing recurs, so there is nothing to cancel.

7. Availability and warranties

The service is provided as it is. We do not warrant uninterrupted or error-free operation, and we do not guarantee that any particular message is delivered or reaches an inbox rather than a spam folder — the receiving mailbox provider decides that, not us.

Where a plan you bought states a specific service commitment, that commitment applies to that plan. Nothing else on the website is a promise of a service level.

8. Liability

To the extent the law allows, we are not liable for indirect or consequential loss, for lost profits, or for loss arising from mail that was not delivered or was delivered late. Our total liability for any claim is limited to the amount you paid us for plans in the thirty days before the claim arose.

Nothing here limits liability that cannot be limited by law, including for fraud or for death or personal injury caused by negligence.

9. What you are responsible for

You are responsible for the mail you send, for having the recipient’s consent to send it, and for complying with the law that applies to it where you are and where the recipient is. If a claim is brought against us because of mail sent with your key, you will cover what it costs us.

10. Changes to these terms

We may change these terms. The current version is the one published here, and it applies from the date at the top of this page. A plan you bought before a change keeps the volume and window it was sold with; continuing to use the service, or buying again, accepts the version in force at that moment.

11. Law and disputes

These terms are governed by the law of [GOVERNING LAW JURISDICTION], and the courts of [COURTS JURISDICTION] have exclusive jurisdiction over any dispute arising from them. If mandatory consumer law where you live gives you rights these terms do not offer, those rights apply.
