● Built for email that actually reaches the inbox

Everything you need.
Nothing you don’t.

DMARC-compliant forwarding with SRS, ARC sealing, health scoring, DNS monitoring, webhooks, and a full developer API. Zero spam-folder drama.

SRS + SPF Fixed Forever

Traditional forwarding breaks SPF. Arc-Relay rewrites the sender automatically so Gmail, Outlook, and every major provider see a clean pass.

  • Automatic Sender Rewriting
  • 100% SPF alignment
  • Works with any custom domain
✅ SPF: PASS

DKIM Preserved + Signed

Original DKIM signatures stay intact through forwarding. Our ARC chain proves they passed at origin — so receivers still trust the message.

Pro+ Add your own DKIM signature to forwarded messages for full domain-level authentication.
DKIM: PRESERVED
+ DKIM: SIGNED PRO

ARC Sealing

The magic layer. Arc-Relay adds a perfect ARC chain so even after forwarding, Gmail/Outlook/Yahoo still trust the original authentication.

→ 100% DMARC pass-through guaranteed

DMARC = PASS
