No SDK to install. It is REST and JSON, and the integration is published as a skill — your agent reads it and writes the client, or you do, in the language you are already working in. Sign up free, verify a domain, and send.
An SDK serves the four languages we chose and nobody else. We publish the integration itself instead — read it once, in your editor or in your agent, and write the client in whatever language you are already using.
One flat window, no metering surprise, and a paid plan renews every 30 days until you cancel it in the billing portal. Those are the same numbers GET /plans returns.
REST, and an SMTP relay if you would rather not change code at all. No client library to install — the integration is published as a skill your agent or your editor can read.
Copy four records, and we poll your registrar until they land. No guessing whether propagation finished.
Full message bodies, headers and SMTP responses. Replay a failed send straight from the log view.
Signed payloads for delivered, bounced, opened and complained, with automatic retry and a dead-letter queue.
A plan is a 30-day window bought with a card in a Stripe checkout, and it renews until you cancel it. When the volume runs out the next call answers 402, and the volume comes back when the window renews or when you pick a bigger plan on the billing page.
Compatible request shape with the API you are probably already using. Change the base URL and the key.
Shared pools tuned per mailbox provider, an optional dedicated IP with automatic warmup, and bounce and complaint handling you do not have to write. If a mailbox provider throttles you, we back off and retry rather than burning the address.
Every team signs with its own key on its own identity, so reputation is earned and lost per sender rather than pooled. That is what makes it safe to hand an agent a working address in the same second it pays for one.
Create an account, verify a domain, and send — 3,000 emails a month on the free tier, no card. One key works over REST, SMTP and MCP, so your agent can use it too.
