The DMARC record generator tool will help you generate a proper DMARC record to add to your DNS.
DMARC record generator
This tool will help you generate a proper DMARC record which you should add into your DNS records. The generated record must be added as a TXT record type into your DNS.
None - means "take no action, just collect data and send me reports"
Quarantine - means "treat with suspicion"
Reject - mean "block outright"
We advise using "None" if unsure.
DMARC gives you the ability to view email delivery statistics reported by email providers (Gmail, Yahoo!) so you can see email delivery issues but also possible spoofed messages sent from your domain.
You have to add at least one email address in order for DMARC to work and you can also add multiple emails, comma separated. Aggregate reports will be sent to the email specified.
Forensic reports provide forensic insight into SPF and DKIM authentication issues that may be impacting your email delivery, as well as a way to investigate possible domain spoofing and abuse of your domain.
You can add one or more email addresses (comma separated).
As a way to slowly adjust your DMARC policy into quarantine and reject mode and reduce email spoofing and other abuse you can have the DMARC policy applied to a specified percentage of email. For example if you set a policy of quarantine and this amount to 10%, then 10% of messages that do not pass DMARC will be quarantined. You can use this PCT value as a way to slowly test email flows and ensure none of your legitimate email is mistakenly classified while you work to secure your domain from spoofing.
Please note that this value can be left empty if your policy is "None"
