Email signature management
Every employee. One brand. Zero copy-paste.
OwnSig gives IT and marketing central control of email signatures across Microsoft 365 and Google Workspace — synced from your HRIS, deployed automatically, assisted by AI, and measured with privacy-safe analytics.
Free plan for one user · No credit card required
Works with the tools you already run
WYSIWYG builder with client-accurate previews
Edit signatures in a live preview and see exactly how they render in Gmail and Outlook — including blocked-image behavior — before anyone sends a thing.
HRIS-powered profiles & SSO
Connect Workday, BambooHR, or HiBob and profiles stay in sync automatically — names, titles, photos, phone numbers.
Deploys to Microsoft 365 & Google Workspace
Push signatures to every mailbox with the platforms' native APIs. Mail never routes through OwnSig.
Governance built in
Four-level role-based access, an approval workflow for member edits, a full audit log, and org-wide policies — lock the layout, let data flow from systems of record.
“You wouldn't let your staff design their own business cards — why let them design their own email signature?”
Built to enterprise security standards
SOC 2 and ISO/IEC 27001 control standards, UK GDPR-ready data handling with ICO-aligned practices, dedicated single-tenant cells for Enterprise, and zero third-party trackers on this site or in any signature we render.
