gSignature review
A flexible, budget-conscious choice for centralized signatures across mixed email environments.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
gSignature is a cloud-based platform for creating, deploying, synchronizing, and updating employee email signatures. It is designed for organizations that need centralized control across domains, groups, organizational units, or entire domains, with support for Google Workspace, Microsoft 365, Outlook, and Exchange Online. Administrators can create custom HTML signatures with variables, links, banners, and legal disclaimers, while assigning separate internal and external versions and controlling employee editing permissions.
The plan structure covers different levels of administrative control. Free provides a free plan with per-user pricing. Core adds centralized HTML email signature management and core implementation features. Growth adds advanced integrations, reporting, and template-management capabilities. Enterprise adds individual onboarding, dedicated SLAs, extended permissions, proxy server options, and custom-domain options. A 14-day free trial is also available. This makes gSignature suitable for teams that want to start without a paid commitment, while larger organizations can move toward more specialized administration and service terms.
Its platform fit is a major strength. gSignature synchronizes employee data with Google Workspace, Microsoft 365, Outlook, and Exchange Online, supports CSV import and export, offers Gmail deployment through a Chrome extension, and provides API access. Server-side signature insertion helps apply signatures across email clients and systems, while automatic updates reflect directory changes. Analytics cover clicks, opens, CTR, and element performance. Teams seeking centralized management, automation, and measurement should find the feature set well aligned; organizations specifically seeking open-source software, or Gmail-only teams that do not need broader administration, may prefer a narrower option.
