DMARC Checker - Checks your emails for DMARC/DKIM/SPF compliance

DMARC Checker is a free online tool that checks if DMARC is properly set up for your emails. DMARC, building on DKIM and SPF, stops bad actors from using your domain in phishing attacks and email fraud. It also helps improve your email delivery rates as more email providers require DMARC.
