Connecting your Mailpro SMTP relay to an AI agent — like ChatGPT Operator, Claude, n8n or your own Python/Node script — lets the agent send polished, deliverable emails on your behalf. Here's the safe way to do it.

Why this matters: AI agents that send mail through random SMTPs end up in spam, get rate-limited, or leak credentials. A managed SMTP with TLS, DKIM and reputation handling solves all three.

Step 1 — Get your Mailpro SMTP credentials

  1. Sign in to Mailpro → Account → SMTP / Integrations.
  2. Copy host (smtp.mailpro.com), port (587), username and generated password.
  3. Store them in your AI platform's secret manager — never in the prompt.

Step 2 — Configure the AI agent / GPT Operator

  1. In your tool's "Tools" or "Actions" config, add an SMTP send action.
  2. Plug in: host, port 587, STARTTLS on, AUTH LOGIN.
  3. Set the From address to a verified domain (with SPF + DKIM in Mailpro).
  4. Define the input schema: to, subject, html, text.

Step 3 — Test deliverability

  • Send a test message to your own inbox first.
  • Inspect headers for SPF=pass and DKIM=pass.
  • Hit a Gmail and an Outlook inbox to validate rendering.
  • Watch the Mailpro dashboard for delivery, opens and bounces.

Security best practices

  • Give the agent a scoped SMTP password — separate from the main account.
  • Rate-limit outbound calls to avoid runaway loops.
  • Always require human approval before mass sends.
  • Rotate the SMTP password if the agent's environment is shared.
