The first step to start implementing DMARC is to update your DNS record as instructed by our setup.
However you may not directly see results in the tool.
ISPs (/ DMARC report senders) may cache the results of the DNS records for up to 72 hours (independent of the TTL of your DNS records).
So, you should see results in the tool (for email sending domains) within 72 hours after updating your DNS records.
Is my email flow configured correctly?
While implementing DMARC you will use the DMARC data to analyze your current email flows. You can do this by checking the data and verifying that your sending sources are configured correctly.
After updating such a flow it can be useful to verify that changes have been made correctly. DMARC Analyzer provides a tool to check the authentication status of your outgoing email flows. Send an email to email@example.com from the source you’d like to test. Our tool will automatically analyze the authentication status for this mail.
The results will be send back to the originator (From header) of the tested mail.
Using this tool you can immediately check if configuration changes take effect without having to wait for the DMARC data.
Please note that if you’re testing an updated DNS record (either DKIM or SPF), there could be DNS cache involved which influences the result. Updates to your SPF record should always be tested before performing them by using our prevalidation SPF checker.
