What Are the Best Practices to Prevent Authentication Failures?
To avoid these issues, adhere to the following best practices:
Regularly Update SPF Records: Ensure all your sending domains and IP addresses are included in your SPF record. Correctly Configure DKIM: Implement DKIM by adding a valid signature to your outgoing messages that aligns with your domain. Implement a DMARC Policy: Use a DMARC policy to align SPF and DKIM and receive reports on authentication failures. Monitor DNS Settings: Regularly check and update your DNS settings to prevent disruptions. Test Before Sending: Use email testing tools to verify authentication status before launching campaigns.
