DMARC Analyzer

You can only have one SPF record for one domain or subdomain. If you publish multiple SPF records, your emails will fail SPF authentication.

Yes, you can publish more than one DKIM record on your domain. DKIM records will differ by the DKIM selectors in order email receivers can find the right record in DNS to authenticate emails by DKIM.

The same domain appears more than one time in the Domains Overview dashboard if the DMARC policy and/or percent of the emails to apply the policy to was changed after the record publication in DNS or if the pct= tag was missing in the report.
