Built for teams who ship email in production
Every request is authenticated, rate-limited, and scoped to your account before it touches AWS SES.
Scoped API keys
Keys expire, rotate with a grace window, and revoke instantly. A revoked key and an unknown key return the same error.
Domain verification
2048-bit DKIM, SPF, and a dedicated MAIL FROM subdomain, verified through the same flow as the API.
Atomic rate limiting
Limits run as a single Redis script, so concurrent requests cannot race past your quota.
Header injection blocked at the schema
Every field that reaches a mail header is checked for carriage returns and control characters before it is accepted.
SSRF-safe webhook delivery
Webhook targets are resolved, checked against private ranges, and the verified IP is pinned for the actual connection.
One endpoint, whichever language you call it from
