How it works

Three steps to your first webhook

01

Create an address

We generate a unique email address. Configure your webhook URL and payload format.

02

Receive emails

Point senders to your address. Built-in spam filtering and email authentication at the edge.

03

Get webhooks

Every email is parsed and POSTed to your URL as signed JSON. Retries on failure, delivery tracking included.

Features

Built for developers

HMAC-signed webhooks

Every payload signed with your per-address secret. Verify authenticity server-side with timing-safe comparison.

Automatic retries

Failed deliveries retried with exponential backoff. Up to 100 attempts over 24+ hours.

Full-text search

Search email history by subject, sender, recipient, or body. Powered by SQLite FTS5.

SPF / DKIM / DMARC

Email authentication results parsed and included in every webhook payload automatically.

Simulation mode

Test without a webhook URL. Emails stored and viewable in the dashboard. Switch to live when ready.

REST API & MCP

Full programmatic access. REST API with Bearer auth, plus an MCP server for AI agent integration via OAuth.

Reseller mode

White-label email infrastructure. Create sub-accounts via API, track per-customer usage, aggregate billing.

Developer docs

Interactive API reference, MCP setup guides, AI-ready prompts, and webhook payload examples.
