Using a CNAME-type DMARC record provided by EasyDMARC is completely safe, and receiving mail servers treat it the same way as a traditional TXT-type DMARC record.
EasyDMARC provides a CNAME-type DMARC record to publish in the DNS to activate the Managed DMARC solution. This setup allows you to manage your DMARC policy directly from the EasyDMARC platform. After activation, you no longer need to edit your DNS zone for DMARC changes, as everything is handled inside your EasyDMARC account. This also helps prevent the human errors that often occur when manually working with complex TXT records.
The reason why EasyDMARC provides a CNAME-type DMARC record is straightforward. It lets EasyDMARC host and maintain the actual DMARC TXT record for you. While you publish a CNAME in your DNS, that CNAME simply points to and resolves into a standard TXT-type DMARC record.
When your DMARC record is published as a CNAME, receiving mail servers follow it and ultimately read the TXT record hosted by EasyDMARC. From their perspective, nothing changes, and they still see a normal TXT DMARC record.
Please find the example below, where you can see,
1. The query performed by the servers when looking up the domain’s DMARC record
2. The CNAME record, published in your DNS to activate the Managed DMARC solution.
3. The TXT-type DMARC record that the CNAME points to, which is what recipient mail hosts actually see when they perform a DMARC lookup for your domain.
In short, using the CNAME-type DMARC record suggested by EasyDMARC to activate the Managed DMARC solution is safe. It provides centralized management, reduces misconfiguration risks, and ensures that recipient servers consistently access a valid DMARC record.
