Audited & certified
For cloud deployment, messages are stamped in transit and handed straight back to your email platform. We process MIME content in memory, add the signature, and never persist message bodies.
Single sign-on, multi-factor authentication, granular role-based access control, and complete audit logs give you full visibility and control over who can do what.
Join 2,500+ companies turning email signatures into their most consistent, on-brand, and measurable channel.
