HOW IT WORKS

Take email signatures off IT’s plate

Own every Google Workspace signature from one dashboard

SETUP SECURITY REQUIREMENTS

Connect to Google Workspace directory in minutes

  • Connects to Google Workspace via the Google Directory API with read-only directory access
  • One-time super admin authorization to connect your Google Workspace account
  • Syncs employees names, titles, departments, and phone numbers from Google Directory daily
  • Assigns signature templates by OU, group, or custom rules without per-user configuration
  • Client-side mode writes signatures directly into Gmail settings, so DKIM stays intact

Satisfy your security review with ISO 27001 and SOC 2

  • ISO 27001, ISO 27018, and SOC 2 Type II certified
  • GDPR and CCPA compliant and HIPAA ready, with a signed DPA
  • Data encrypted in transit (TLS 1.3) and at rest (AES-256)
  • RBAC with Admin, Designer, and IT roles
  • SAML 2.0, SSO, and MFA available for admin access control

Confirm readiness for deployment

  • A Google Workspace account with super admin credentials for initial authorization and setup
  • Google Directory must be active; WiseStamp imports employee data via read-only API access
  • Gmail must be the organization’s active email client for signature deployment to function
  • Admin dashboard requires a modern browser: Chrome, Firefox, Edge, or Safari will work
  • No on-premise hardware required. WiseStamp is a fully cloud-based SaaS on Google Cloud

We just had to configure WiseStamp one time. After that, each user has been synced automatically. It works like a charm!

WiseStamp syncs from your Google Workspace Directory daily. Job titles, phone numbers, and departments update automatically when records change.

SIGNATURE LOCKING

Stop employees from changing or breaking signatures

Admins lock the template. Employees can update approved personal details. The branding, disclaimers, and design always remain intact.

GROUP ASSIGNMENT

FAQ

What is a Google Workspace signature manager?

A Google Workspace signature manager is a third-party platform that gives admins centralized control over Gmail signatures across an entire organization. Unlike native Google Workspace, a signature manager deploys branded templates, locks signature content, syncs employee data from Google Directory, and enforces legal disclaimers by department.

Does Google Workspace natively support centralized email signature management?
