One REST API for transactional email: send, score every message for deliverability, and relay through your own SES or Resend account — managed and monitored for you.
See pricingRead the docs
One REST API sends the message, scores it for deliverability, and relays it through your own SES or Resend account. This is the log you get back — no “delivered” black box.
Built for developers who want the job done right — and to see exactly how it was done.
Every send returns a 0–100 score with a full breakdown — authentication, content, reputation, engagement — plus plain-language flags telling you exactly what to fix.
POST /v1/scores to validate and score any payload without relaying anything. Test templates and content safely.
RelayForge never owns mail servers. Production relay runs on your own AWS SES or Resend account — provisioned, configured, and monitored for you. No shared-IP reputation roulette.
The request shape you already know. Validation, auth, and error codes are explicit and documented — no surprises.
Every request is appended to a metadata-only JSONL log. Message bodies and API keys are never written to logs.
Monthly billing, cancel anytime. No per-seat games, no surprise bills.
For the indie hacker sending their first 50K emails.
For growing SaaS teams that need more volume and more domains.
For high-volume senders who want a deliverability partner.
