# Mailrith

> Mailrith is a fixed-price email marketing platform for solopreneurs. Public paid plans include unlimited subscribers, visual automations, hosted forms and landing pages, AI-assisted drafting, a public API, official SDKs, and an official MCP server for agent runtimes.

Use the linked markdown files when you need clean context. Use the OpenAPI document for exact request and response schemas. Use authenticated capability discovery before issuing write requests because capabilities depend on the workspace key.

Important interpretation notes:
- Mailrith sends through customer-chosen email delivery services; agents should not assume Mailrith is an inbox or the service that delivers the email.
- Public API keys are workspace-scoped. Do not add a separate workspace identifier unless the documented endpoint asks for one.
- Resource permissions are consistent: a write permission covers every public write operation for that resource. Limit the tools available to an agent when a workflow should use only a subset.
- Public form, landing-page success, status, and non-production pages are intentionally non-indexable.
