Introduction

MiniMailer is EU-resident email infrastructure for developers and AI-agent builders: a REST API for sending transactional and marketing email, receiving inbound email through webhooks, and tracking every delivery event — with native MCP support so agents can send and parse email without custom integration.

How the docs are organised

This section is the tutorial layer — task-oriented guides in reading order:

• Getting started — create an account, verify a sending domain, send your first email.
• Sending — transactional sends, idempotency, tracking, and rate limits.
• Campaigns — send one message to an audience: audiences, scheduling, and the campaign lifecycle.
• Receiving — inboxes and inbound email parsing via webhooks.
• Webhooks — event types, signed deliveries, retries, rotation, and replay.
• MCP — connecting AI agents to MiniMailer's native MCP server.
• MCP examples — copy-paste agent-prompt recipes for the MCP server.

Two companion sections cover everything else:

• The API Reference documents every endpoint and is generated straight from the OpenAPI specification, so it is always in sync with the API.
• The Knowledge Base answers the operational questions — deliverability, sender reputation, bounces, and EU data residency.

The changelog tracks what ships.

The API in one paragraph

The API lives at https://api.minimailer.app, speaks JSON:API (application/vnd.api+json), and authenticates with bearer tokens scoped to exactly what each integration needs. Every feature is API-first — the dashboard is a companion for observability and configuration, not a gate. If you'd rather read a spec than prose, start at the API Reference.
