  Exclaimer is an email signature management platform used by IT, marketing, and
  sales teams to centrally create, deploy, and govern corporate email signatures
  across Microsoft 365, Microsoft Exchange, and Google Workspace. It manages
  signatures for more than 9 million email accounts, adding campaign banners,
  meeting-branding backgrounds, click-tracking analytics, directory
  synchronization with Azure AD and Google Directory, and role-based access
  control. Exclaimer does not publish a public developer API reference, but
  operates a multi-region Exclaimer Cloud with a real-time status page and a
  strong security and compliance program (SOC 2 Type II, ISO 27001/27018, HIPAA,
  PCI DSS, CSA STAR, Cyber Essentials).
