DMARC Record Checker
Inspect your DMARC DNS record, evaluate your policy enforcement (none, quarantine, or reject), and verify compliance with 2024+ Google and Yahoo sender guidelines.
What is DMARC and why is it mandatory?
DMARC builds upon SPF and DKIM authentication. It tells receiving mail servers (like Google, Microsoft, and Yahoo) what to do when an email claiming to come from your domain fails SPF or DKIM checks, preventing cybercriminals from impersonating your brand.
Enforcement Policies
'p=none' monitors traffic without affecting delivery; 'p=quarantine' routes suspicious mail to spam; and 'p=reject' blocks spoofed emails outright.
Mandatory for Bulk Senders
Google and Yahoo require all domains sending over 5,000 emails per day to have a published DMARC policy with a valid reporting address.
Receive Diagnostic Reports
Adding 'rua=mailto:dmarc@yourdomain.com' sends daily XML summaries detailing which IP addresses and services send mail under your domain name.
