Brevo SMTP checklist before production

A focused checklist for founders configuring Brevo SMTP relay before sending checkout receipts, digital delivery links, or other transactional email.

Email checks

  • Use the Brevo SMTP relay host and a production sender address on the project domain.
  • Keep the SMTP login and password in environment variables or secret storage, never in source code.
  • Verify SPF, DKIM, and DMARC for the sender domain before relying on production delivery.
  • Send one transactional test email and inspect inbox placement plus received message headers.

Free helpers
