Authorize domain-wide delegation
In the Google Admin console, add Signatura's service account client ID under Security → API controls → Domain-wide delegation with the Gmail settings and directory read scopes. No per-user consent prompts.
Built for Google Workspace admins
Google Workspace email signature management
Design one branded template and Signatura applies it to every Gmail mailbox in your domain — using domain-wide delegation and your Google Directory data.
How Signatura connects to your Workspace domain
Sync Google Directory
Signatura reads your Workspace directory so each signature is filled with the user's real name, job title, department, phone and photo — no spreadsheets.
Enforce signatures on every mailbox
Signatures are written directly to Gmail send-as settings, so branding stays correct across the web client, mobile and new devices.
Keep it in sync automatically
New hires, promotions and department moves flow through from the directory, so nobody ships a stale signature.
What Workspace admins get
- Template variables such as {{full_name}} and {{job_title}} rendered live as you edit, populated from Google Directory fields.
- Rules per team — assign different templates by department, job title or individual user with clear precedence.
- Audit trail — every template edit, connection change and enforcement run is logged with user and timestamp.
- Microsoft 365 too — run both platforms from one place if your organization is mixed.
- Multi-tenant for partners — IT providers can manage every client domain from a single console. See the partner program.
