Create a DMARC DNS Record
Customize the options below to generate a DMARC record, which will be shown in the input field above.
This tool allows you to create DMARC DNS records, which can be used when you are hosting an email server and want to provide an extra layer of security, so other email providers will trust your emails.
Select the options you want and copy the text. The DNS record should be a TXT record in the _dmarc subdomain (e.g. _dmarc.example.com) with the content being the text above.
Using DMARC prevents your emails from ending up in the receiver's spam folder by telling email servers how strictly to handle validation with DKIM and SPF. It is highly recommended to set up both of these before using DMARC.
