Secure Your Email Domain with DMARC: A Step-by-Step Guide

Protecting your email domain from spoofing and unauthorized use is essential in maintaining trust and brand reputation. One effective way to achieve this is by implementing DMARC (Domain-based Message Authentication, Reporting, and Conformance). In this short guide, we'll walk you through the process of adding a DMARC record to your sending domain, ensuring that only legitimate emails are delivered using your domain name.


  1. Access your domain hosting provider's control panel or DNS management section.
  2. Locate the DNS records for your domain and navigate to the TXT records section.
  3. Create a new TXT record with the host/name as "_dmarc.{yourdomain}" (replace "{yourdomain}" with your actual domain name).
  4. In the value field, enter the following: v=DMARC1; p=reject;

By adding a DMARC record with the specified TXT record format, you are taking a proactive step in securing your email domain. This DMARC policy instructs email receivers to reject any messages that fail authentication, safeguarding your domain from unauthorized use. Remember to periodically review your DMARC reports to gain insights into email authentication issues and maintain a strong email reputation.

Implementing DMARC is a vital component in protecting your domain from email threats. Follow these instructions to fortify your email communication and preserve the integrity of your brand.

If you encounter any difficulties or have questions along the way, don't hesitate to reach out to your domain hosting provider for assistance.
