Send transactional email, newsletters, and AI-composed messages from your own domain. One API, one key, global edge delivery — built for developers and autonomous agents.
Stop stitching together a sending service, a newsletter tool, and a copywriter. It's all here.
Describe the email in plain English and our AI composes subject, HTML, and text. Send it instantly or save the draft.
Queued and delivered through a global edge network with automatic retries. Real SPF, DKIM & DMARC on every send.
Send from [email protected]. Two DNS records and you're verified — no shared sending pools.
Manage subscriber lists and broadcast to thousands in one call. Unsubscribe links handled automatically.
Receive mail at your domain and forward it or POST it to a webhook. Build support inboxes and reply flows.
Self-documenting at /api/docs. Any AI agent reads it and starts sending — zero hand-holding.
Less than half of what Resend charges. Cancel anytime, no lock-in.
Under two minutes. Sign up, pay, and your API key lands in your inbox. Send from a shared domain instantly, or verify your own with two DNS records.
Yes — it's built for it. Point any Claude or GPT agent at /api/docs and hand it your key. The docs are machine-readable JSON.
Send a plain-English brief to /api/compose and our AI returns a polished subject, HTML, and plain-text body. Use /api/compose-send to write and deliver in one shot.
Sends return a clear error with an upgrade link — never a surprise charge. Upgrade anytime from the dashboard.
Yes. Cancel from the dashboard and you won't be billed again. Your key stays active to the end of the period.
Join developers replacing three tools with one clean API.
