Challenge

As a trusted e-signature platform serving more than 61,000 businesses, SignWell depends on secure, reliable email delivery for agreements and customer communications. Increasing phishing attacks targeting e-signature workflows and the need to maintain strong inbox placement made modern email authentication a business priority.

„Skysnag made it easy to successfully implement DMARC, protect our domain, and avoid any mistakes during the implementation process. I highly recommend Skysnag to anyone looking to set up DMARC for their domain.“

Ruben Gomez — CEO, SignWell

Why Skysnag

Security value

Skysnag enabled DMARC enforcement with a strict p=reject policy while detecting blacklisting risks and blocking spoofing attempts.

Operational value
