Green Signature

What Green Signature does

Green Signature is a privately held software vendor headquartered in Schaumburg, Illinois, operating in the unified email signature management category since 2016. The company sells two core products: GreenSignature Cloud, a subscription-based solution for Microsoft Office 365 tenants, and Green Signature Manager - Exchange Edition, an on-premise deployment for Microsoft Exchange Server environments. Both products apply centrally designed, policy-driven email signatures to outgoing messages across web and mobile clients including Outlook, Android, iOS, and iPad devices. The platform integrates with Microsoft Azure Active Directory for attribute synchronization and single sign-on, and is hosted on Microsoft Azure datacenters across all regions for data residency and compliance.

The platform is built around a web-based drag-and-drop Signature Editor that enables non-technical administrators to design templates containing logos, banners, social media icons, and marketing content, with policy rules distinguishing new messages from replies/forwards and internal from external recipients. A Software Support Agreement (SSA) provides recurring updates, bug fixes, and technical support for Exchange Edition customers.

Green Signature generates revenue through three streams: one-time perpetual licenses for the Exchange Edition ($145 to $2,475 depending on user count), mandatory SSA subscriptions on Exchange Edition, and per-active-user monthly cloud subscriptions for the Office 365 product ($1.32 per user per month, 5-user minimum). The company serves both enterprise and SMB segments via direct sales, a 14-day free trial, and a partner/reseller channel program, and claims thousands of customers worldwide.
