ExSign
Simplify email signature management in Microsoft 365 with ExSign Email Signature software.
About ExSign
ExSign is an email signature management software developed by Hosting Controller, designed to provide centralized control over email signatures and disclaimers for Microsoft Exchange Server and Microsoft 365 environments. It allows administrators to create, manage, and apply consistent, professional signatures across the entire organization using pre-defined rules. ExSign offers a web-based portal for easy management, role-based access control for delegation, and supports both server-side and client-side signature application. It integrates with Active Directory to pull user profiles, ensuring accurate contact details. The software is available in two editions: one for on-premises Exchange Server (requiring a physical machine) and a cloud-based service for Microsoft 365 (no hardware required). ExSign helps turn every email into a marketing channel by enabling the addition of banners, logos, and social media icons. With features like multi-level access, pre-built templates, and reporting analytics, ExSign aims to streamline signature governance and compliance. The product is available with a free trial, and deployment can be done on-premises for Exchange or via cloud for Microsoft 365. Hosting Controller positions ExSign as a solution that enhances brand consistency and reduces the burden on IT staff.
