# Docs

- Docs: Guides, concepts, and recipes
  - [Overview](/help/guide): Isolated inboxes for E2E tests. Keep the production sender; change only the recipient.
  - [Quickstart](/help/guide/quickstart): From a new account to a test that reads a real email.

  - **Concepts**
  - [Inboxes](/help/guide/inboxes): Temporary inboxes for tests, permanent addresses for everything else.
  - [Messages](/help/guide/messages): What Mailwurf reads out of an email, and how to pick the link or code a test needs.
  - [Waiting](/help/guide/waiting): One open request until the mail is there. No sleeps, no polling loops.
  - [Sending](/help/guide/sending): Send mail from an inbox, to test how your app handles incoming email.
  - [Transactional mail](/help/guide/transactional): Send receipts and notifications from your app as your own domain.
  - [Send over SMTP](/help/guide/smtp): Connect an app or tool that sends mail over SMTP, with your API key as the password.
  - [Limits](/help/guide/limits): Sizes, lifetimes, and quotas.

  - **Recipes**
  - [Playwright](/help/guide/playwright): Create an inbox, let the app send normally, wait, then follow the link.
  - [Cypress](/help/guide/cypress): Call Mailwurf from Cypress tasks, so the API key never reaches the browser.
  - [Vitest and Node](/help/guide/vitest): Test the emails your backend sends, without a browser.
  - [CI](/help/guide/ci): Run email tests in GitHub Actions and other pipelines.
  - [Connect an AI agent (MCP)](/help/guide/mcp): Let Claude Code and other agents create inboxes, wait for mail, and send replies. No API key.

  - **Help**
  - [Troubleshooting](/help/guide/troubleshooting): The usual reasons a test does not get its email.
- Dashboard: Account, organization, keys, and addresses
  - [Account](/help/dashboard): Sign up, confirm your email, and sign in to the dashboard.
  - [Organizations](/help/dashboard/organizations): The boundary for members, API keys, and every inbox.
  - [API keys](/help/dashboard/api-keys): One key per environment. Shown once, revocable at any time.
  - [Permanent addresses](/help/dashboard/inboxes): Fixed addresses that keep receiving mail, and the mail view for every inbox.
  - [Custom domains](/help/dashboard/domains): Receive test mail on a domain you own, and optionally send as it.
- @mailwurf/e2e: TypeScript package for tests
  - [@mailwurf/e2e](/help/e2e): Fetch-only TypeScript package for the mailbox API. Playwright is a consumer, not a dependency.
- API: HTTP and OpenAPI reference
  - [API Reference](/help/api): OpenAPI for the Mailwurf mailbox API.
  - [HTTP API](/help/api/http): Plain HTTP under /api/v1. @mailwurf/e2e is optional.
  - [Discovery](/help/api/discovery)
  - [Inboxes](/help/api/inboxes)
  - [Messages](/help/api/messages)
  - [Emails](/help/api/emails)
