What it is
gSignature centrally manages and distributes email signatures across an organization. Administrators can manage signatures by domain or organizational unit and assign a default for new employees. Employee details can sync from supported email environments, arrive through CSV imports, or be edited by employees or administrators. Templates can use HTML, links, banners, more than 25 built-in employee variables, or custom parameters. Administrators can update banners across employees and measure campaign results in Google Analytics. The product documents connections to Google Workspace, Microsoft 365, Outlook, and Exchange Online, along with CRM connections such as Pipedrive, Salesforce, and HubSpot, plus Zendesk. Google Workspace users can update Gmail signatures through the Gmail API, and server-side mode can add signatures to outgoing mail, including messages sent from non-Gmail clients used with Google Workspace. A free plan and 14-day trial are listed. Initial registration requires a Google Workspace administrator. The product is available on Android, macOS, Windows, web, and as an extension.
