Verifying Your DNS Records

After adding DNS records to support WP Mail SMTP, we recommend verifying that they’ve been implemented correctly. This step helps ensure optimal email deliverability by confirming that your outgoing emails are authenticated.

There are a couple of ways to verify your DNS records:

  • Sending a test email: Utilize WP Mail SMTP’s built-in tool for sending a test email. If there’s an issue with your DNS records, an error notification will pop up.
