There are two ways to create a DMARC record or update your existing DMARC record to start interacting with the Valimail Authenticate product. 

The most common way is to add a DMARC NS record to your DNS to point to Valimail. We have numerous articles on how to do that in the app itself or in this section of our KB. Most of our customers use this method because it leverages the functionality of the platform when it's time for you to move your domain to DMARC enforcement. It's also the fastest method.

That said, some customers have provided feedback that they'd prefer to create a DMARC TXT record temporarily, or at least update their existing record while they test out our platform. That's fine too. Here is how you would do that:

Update your existing _dmarc TXT record. This allows Valimail to receive your DMARC aggregate reports.

If you already have a _dmarc TXT record: add to the "rua" parameter. 

Your TXT record should look as follows:

"v=DMARC1; p=none;;"

If you don't have a _dmarc TXT record then create the following TXT record in DNS:

Type              TXT
Host/Name   _dmarc.<your domain name>
Value        "v=DMARC1; p=none;;"


If your domain name is, the host/name value to create for the TXT record would be


  • If a _dmarc TXT record already exists, be sure to only add to the "rua" parameter; do not modify any other parameters in the record unless you're sure of what you're doing, otherwise you may impact email deliverability for your organization.
  • No change to your email flow will occur. Valimail will see no PII.
