  7. Test Inbox Placement: Utilize inbox testing services like GlockApps or Litmus to verify if your emails are being delivered into primary inboxes rather than getting trapped in junk/spam folders across different email clients.

Best Practices for Email Authentication

To ensure proper email deliverability and prevent common deliverability problems, it is crucial to implement strong email authentication practices. By following these best practices, you can enhance your email sender reputation and maximize the chances of your emails reaching the intended recipients’ inboxes.

Here are some key steps you should take:

  1. Implement SPF (Sender Policy Framework): Set up SPF records in your DNS to specify which servers are authorized to send emails on behalf of your domain. This helps prevent spammers from spoofing your domain and improves email deliverability.

  2. Configure DKIM (DomainKeys Identified Mail): Generate a unique cryptographic signature for each outgoing message using DKIM. This allows receiving mail servers to verify that the message was indeed sent by an authorized sender and hasn’t been tampered with during transit.

  3. Enable DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC helps protect against phishing attacks by specifying how email receivers should handle unauthenticated messages from your domain. It provides valuable reporting insights while allowing you to instruct ISPs on what actions they should take if an incoming email fails authentication checks.

  4. Regularly Monitor IP Reputation: Keep tabs on the reputation of the IP addresses used for sending emails from your domain. Being aware of any blacklisting or poor feedback associated with these IPs can help identify potential issues and allow prompt action to resolve them.

  5. Manage Feedback Loops: Sign up for feedback loops provided by major ISPs such as Gmail, Yahoo, or These services alert you when users mark your emails as spam or report abuse, enabling you to address any complaints promptly and maintain a good sender reputation.

  6. Avoid Using Shared IPs: Whenever possible, utilize dedicated IP addresses solely assigned to your organization’s sending infrastructure rather than shared IPs commonly used by multiple senders simultaneously.

By adhering to these best practices for email authentication, you can significantly improve your email deliverability rates and minimize the chances of encountering common problems associated with emails being marked as spam or rejected by recipient servers.
