WordPress SMTP

Send WordPress email through verified SMTP

WordPress can send mail through PHP mail, but that is often hard to authenticate and debug. zaSend gives WordPress a real SMTP relay for WooCommerce receipts, contact forms, password resets, order updates, and admin notifications.

Good WordPress fits

  • WooCommerce receipts and order updates
  • WordPress password reset emails
  • Contact form notifications
  • Membership, booking, and LMS plugin emails
  • Sites that want domain-authenticated SMTP without running a mail server

Setup checklist

  1. Add and verify your sending domain in zaSend.
  2. Create a Domain Sending Key.
  3. Install a WordPress SMTP plugin and enter the settings above.
  4. Send a test email and confirm SPF, DKIM, and DMARC in the recipient inbox.

Common mistakes

  • Using a Gmail or Outlook From address instead of your verified domain.
  • Copying the DKIM host incorrectly when the DNS provider wants the short host name.
  • Testing only with one inbox. Try Gmail and Outlook before inviting real users.
  • Forgetting that marketing newsletters need proper unsubscribe handling.
