8 language SDKs, a CLI, an MCP server, and SMTP relay for any platform that speaks email. One API key, one quota, every direction.
The hosted MCP server at mcp.mailkite.dev lets any MCP-compatible client read, send, and act on email — no custom integration needed.
Drop MailKite into your existing stack. Most integrations are a single config change — point SMTP at smtp.mailkite.dev and you're done.

Every integration uses the same SMTP connection. Your password is your API key — no separate SMTP credential to create.
Point a domain, drop in a webhook URL, and send your first email in minutes. Unlimited domains, no credit card.
