  • Navigate to the "Domain Authentication" section in your SendGrid account.
  • Add the necessary DNS records to verify ownership of your domain.
  • Complete the authentication process by following the prompts provided.

  • In your SendGrid account settings, locate the "Multiple Domains" option.
  • Add each domain you wish to authenticate.
  • Verify the domain ownership by adding the required DNS records.
  • Complete the authentication process for each domain.

Verify Domain Ownership on SendGrid

Verifying domain ownership is a critical step in ensuring that your emails are authenticated and delivered successfully. To verify your domain ownership on SendGrid:
