About Conduit Email

Conduit is a hosted SMTP→Webhook gateway that receives inbound email and delivers it to your application as signed HTTP POST requests. It eliminates polling and mail libraries by parsing messages, signing them with HMAC-SHA256 (X-Conduit-Signature), and forwarding them to your endpoint. Built-in SMTP retry behavior (returns 450 Temporary Failure on undeliverable requests), domain ownership verification via a DNS TXT record, and per-webhook rate limiting protect your app from lost messages and spikes.

Key Features

  • Convert any registered email address into a live webhook endpoint
  • SMTP-native retry behavior (returns 450 Temporary Failure) — no internal queues
  • Signed deliveries with HMAC-SHA256 in X-Conduit-Signature header
  • Domain ownership verification via a DNS TXT record
  • Per-webhook rate limiting to protect endpoints from bursts

Who is this for?

Developers and teams that need to integrate inbound email (alerts, IoT, partner messages, forms) into applications via HTTP webhooks.
