Introduction

MailCraft is the email API for developers — and their agents. Send transactional email, run campaigns and automations, and manage contacts with one API, ten SDKs and an MCP server.

Get an API key Send your first email

Send your first email

1. Add and verify a domain, then a sender on it.
2. Create an API key under Settings → API keys and export it as MAILCRAFT_API_KEY.

  -X POST \
  -H "Authorization: Bearer $MAILCRAFT_API_KEY" \
  -H "Content-Type: application/json" \

    "subject": "Hello from MailCraft",
    "html": "<p>It works!</p>"
