What is Conduit?

Conduit is a hosted service that bridges inbound email to HTTP webhooks. When an email arrives at your Conduit address, Conduit immediately delivers it as an HTTP POST to the URL you configure — no polling, no mail servers to manage.

Getting Started

A step-by-step walkthrough: create an account, create a webhook, verify the delivery signature, and send your first test email.

Using the API

Full reference for every REST API endpoint — authentication, webhooks, delivery logs, security policies, and domains.

Webhook Payload Reference

The JSON structure Conduit delivers to your endpoint, how to verify the signature, payload templates, and custom request headers.

Custom Domain

Verify a domain you own so that you can use your own email addresses (e.g. alerts@mail.example.com) instead of the shared Conduit domain. Covers both the DNS MX record (to route mail to Conduit) and the TXT verification record.

SMTP Security Policy

Restrict who can send email to your webhooks: allowlist source IPs, require SMTP AUTH, enforce SPF and DKIM verification, and limit accepted sender domains.

SMTP Response Headers

Return custom SMTP response codes and messages from your webhook endpoint using the X-Conduit-SMTP-Code and X-Conduit-SMTP-Message response headers.
