Pause before opening a suspicious link.
Use the checker as one signal when assessing an unexpected message. If you are unsure, leave the link unopened and ask your IT support team.
Check a link without opening it yourself.
Links you submit are sent to EasyDMARC for analysis. Do not paste whole emails, passwords, personal information, password-reset links, private document-sharing links or other confidential URLs.
A clean result is not a guarantee of safety. New attacks, compromised websites and later changes may not be detected. Do not open a suspicious link simply because it receives a favourable result.
Choose whether to load this external tool
EasyDMARC provides this checker. It receives the information you submit and technical browser information. Its own cookies and analytics may run when you allow external security tools, even if CompTech analytics is off.
The checker is off until you allow External security tools in Cookie settings.
