How our email signature manager works
Connect to Entra ID (Azure Active Directory) or Google Directory to automatically pull in employee details. If someone changes roles or offices, their signature updates automatically.
Assign signatures dynamically based on practice area, jurisdiction, seniority, or location, ensuring every email is relevant and fully compliant.
From paralegals on mobile to partners on Outlook, every signature stays correctly formatted and all disclaimers are applied—across every device and email client.
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 high availability and low risk.
