Set Up Google's Postmaster Tools

Customers are able to leverage Google's postmaster tools by setting up a TXT record for the From Address domain.

Does not require a dedicated IP and does not require Marketo to set up DNS for the customer.

If you send a large volume of emails to Gmail users, you can use Postmaster Tools to see:

• If users are marking your emails as spam
• Whether you’re following Gmail's best practices
  • Bulk Senders Guidelines - Gmail Help
  • Gmail best practices - G Suite Administrator Help
• Why your emails might not be delivered
• If your emails are being sent securely
