What gSignature is

gSignature centrally manages and distributes email signatures across an organization. Administrators can set signatures for a whole domain or specific organizational units, and choose a default for new employees. Employee information can come from supported email environments, CSV imports, employee edits, or administrator edits. For design, administrators can create HTML signatures with links and banners, drawing on more than 25 built-in employee variables or custom parameters; they can also request a custom HTML design. The product documents connections to Google Workspace, Microsoft 365, Outlook, and Exchange Online, as well as CRM tools including Pipedrive, Salesforce, and HubSpot, and helpdesk software including Zendesk. For Google Workspace, gSignature retrieves employee data and updates Gmail signatures through the Gmail API. A server-side mode can append signatures to outgoing messages, including those sent from non-Gmail clients used with Google Workspace. Administrators can update banners across employees and measure campaign results in Google Analytics. The maker says customer data stays within Google Workspace and Google Cloud, with access limited to authorized administrators. Founded in 2023, the company lists its address in Wrocław, Poland.
