In their own words
AdSigner
AdSigner centrally manages employee email signatures and can deploy them across an organization. It supports distinct branded signatures for departments, roles, regions, locations, or company brands. Campaign banners can carry offers, events, content, or company news in employee emails. Analytics tracks signature and campaign views, clicks, and click-through rates, with reports exportable to Excel, CSV, or JSON. Employee directory data can be synced from Microsoft Entra ID or Google Directory, supplied through JSON endpoints or custom API sources, or imported from Excel, CSV, or JSON files. Deployment options include Microsoft 365 and Outlook add-ins, Google Workspace and Gmail add-ons, AdSigner Agent for Outlook or Thunderbird, HTML copy-and-paste, and API-based deployment. AdSigner says it processes directory data and signature configuration to generate signatures without routing or accessing email content. Its security page states that it is GDPR compliant, offers a Data Processing Agreement, and has an SSL certificate. Administrators can enforce disclaimers and restrict compliance settings through role-based permissions. Standard support is included with subscriptions, with email or chat responses within 24 business hours. The platform lists API, extension, web, and Windows.
