How to add DMARC to your DNS provider

Step1: Visit DNS Hosting Provider and Select Create Record: To add your DMARC record, log in to your DNS Hosting provider. From there, you must find the prompt to button a new record or the TXT section to edit. Interfaces vary depending on the hosting provider. 

Step 2: Select TXT DNS Record Type: Based on the provider, you will likely see a drop-down list of DNS record types. You will want to select the "TXT" one.

Step 3: Add Host Value: In this field, more than likely, you will input the value _dmarc, and the hosting provider will append the domain or subdomain after that value.

Step 4: Add "Value" Information: Two required tag-value pairs MUST be present on every DMARC record. They are "v" and "p".

• The only tag-value pair for "v" is v=DMARC1
• For the "p" tag pair, "p=" can be paired with none, quarantine, or reject. As tag-value pairs, they would look like: p=none or p=quarantine or p=reject

Google recommends that all new DMARC records should at least start with p=none, as this policy value allows you to identify email delivery problems due to the domain's SPF or DKIM so that mail is not accidentally quarantined or rejected.

Step 5: Hit Create/Save Button: Once you have added all of those details, your record should look like the below image. You must hit the save or submit button to generate the record.

Step 6: Validate Record: The last step is to Run a DMARC Record Check to verify that the record you just created has the correct values and syntax.

Note: It will take 30 minutes to 1 hour for the new record to be updated in the system.
