Documentation

Everything you need to point your staging environment at Mailclutch — which is mostly four environment variables.

Debug your emails within minutes

Quickstart

From your first SMTP credentials to your first captured email, in about two minutes. No account needed to try it.

Connect your app

  • SMTP Setup

    Host, port and credentials, with snippets for the usual mailers.

  • Framework guides

    Laravel, Django, Rails, Node.js, Postfix — 23 stacks, with live credentials in every snippet.

  • MCP for agents

    Give a coding agent its own inbox — no account, no API key.

Automate and share

  • API Reference

    Inboxes per run, a blocking wait, a pass/fail verdict on the email — the API for your pipeline.

  • Webhooks

    An HTTP callback or a Slack message on every captured email.

  • Integrations

    Webhooks, Slack, browser notifications and the REST API.

  • White label

    Share links under your own name, on a domain of yours such as sandbox.acme.com.
