How our email signature manager works
Sync contact info from Entra ID (Azure AD) or Google Directory. When someone joins the company, changes roles, or transfers to another location, their signature updates automatically.
Assign templates based on practice area, office, or seniority, so the right message reaches the right client.
Whether an email is sent from the office, remote laptops, or mobile devices, every signature is on-brand and accurate. No exceptions, no manual steps.
Deploy server-side for zero disruption, client-side to support user previews, or go hybrid for both control and flexibility.
Exclaimer is secure by design. With 99.99% uptime, TLS encryption, and active-active global hosting, it’s built for firms that need reliability and data protection.
