AI Integrations

AI tools can send email through Mailtarget when they call a server-side function that owns the API key. The integration boundary is the same as any backend service: the model or agent prepares intent and structured inputs, while trusted application code validates, authorizes, and sends the request.

Integration rule​

Do not expose MAILTARGET_API_KEY to a model runtime, browser, mobile app, or user-controlled tool environment unless that environment is already trusted as backend infrastructure.

Use a function boundary:

  1. The AI agent collects message intent.
  2. Your application validates sender, recipient, content, and policy.
  3. Your server calls the Mailtarget API.
  4. Webhooks or analytics reconcile the final outcome.

Guides​

These guides are retained from the legacy Email API category because they are developer-facing, but both are marked for review since tool APIs and package names can drift.
