Email as Events

Catch Inbound Email
Like You Catch Webhooks

Turn any inbound email into a structured, observable event. Inspect every detail in real time, verify authentication, and forward email content as JSON to your app.

How It Works

Three steps from email to actionable event data.

Generate an Address

Create a unique email address in seconds. Permanent endpoints for production, or temporary ones for quick testing.

Inspect Every Detail

See headers, text and HTML bodies, MIME structure, attachment metadata, and full authentication results in a developer-focused interface.

Forward as JSON

Automatically forward email content as normalized JSON to your app. Same forwarding rules, retries, and replay tools as webhooks.

Built for Developers

Every feature you already use for webhooks now works for email.

Email Authentication

Full SPF, DKIM, and DMARC verification on every email. See at a glance whether the sender is authenticated.

Provider Detection

Automatically identify whether emails were sent via SendGrid, SES, Mailgun, Postmark, Google, or Microsoft.

Replay & Forwarding

Replay any email event to a target URL. Set up automatic forwarding rules with retries and conditional routing.

Localhost Tunneling

Forward email events to your local development server in real time. Same CLI tunnel you use for webhooks.

Export & API

Export email events as JSON or CSV. Full REST API access for programmatic use in CI pipelines, scripts, and integrations.

Team Collaboration

Share email endpoints with your team. Role-based access and audit logs keep everyone aligned.

Use Cases

Anywhere email is an event source.

Transactional Email Testing

Send signup confirmations, password resets, or receipts to your Catchhook address and verify content, formatting, and authentication before going live.

Vendor Email Integrations

Catch notification emails from services that only deliver via email, then transform and forward them as structured JSON to your application.

Deliverability Debugging

Verify SPF, DKIM, and DMARC pass rates across email providers. Identify authentication failures before they affect your users.

Workflow & AI Triggers

Use inbound email as a trigger for automation pipelines. Forward structured data to AI agents, Zapier, n8n, or custom backends.
