Overview
SignatureHQ connects to your Google Workspace domain, syncs your user directory, and lets you design email signature templates that are automatically deployed to every employee's Gmail account. This guide walks you through the full setup in under 15 minutes.

Prerequisites
- A Google Workspace account (Business Starter or above) โ you must be a Super Admin of the domain
- A SignatureHQ account โ sign in at the top of this page with your Google Workspace email
Super Admin required
Installing the SignatureHQ Marketplace app and granting Domain-Wide Delegation requires Google Workspace Super Admin privileges. You can complete setup yourself and then invite non-admin colleagues to help manage signatures.Connect Google Workspace
After signing in and creating your organisation, you'll be taken to the Connect Google Workspace step. The easiest path is the one-click Marketplace install:
- 1Click Install via Google Workspace Marketplace. The Marketplace listing opens in a new tab.
- 2Click Admin install on the Marketplace page and follow the prompts to grant the required permissions to your domain.
- 3Return to the SignatureHQ tab. It will detect the install automatically and show a green Google Workspace connected! confirmation.

After connecting, SignatureHQ imports your users, groups, and OUs from Google Directory. The first sync runs automatically when you land on the dashboard.
You can monitor sync progress from Directory Sync in the sidebar. Once complete, all your Google Workspace users appear under Users.
Info
Sync can take a few minutes for large directories. Subsequent syncs only pull changes and are much faster.Next steps
