How our email signature manager works
Connect to Entra ID (Azure Active Directory) or Google Directory to automatically pull in employee details. Crew changes? Job site moves? Everything syncs automatically.
Trigger different signatures based on job role, department, or location. Every email reflects the right sender and the right message.
Emails sent from jobsite tablets, mobile phones, or HQ desktops all get the same polished signature. No workarounds needed.
Deploy server-side for hands-off enforcement, client-side for user visibility, or hybrid for ultimate flexibility.
Enjoy 99.99% uptime, TLS encryption, and intrusion prevention from the most secure email signature management solution. Exclaimer is built for environments that can’t afford mistakes.
