Why choose device deployment

Real-time visibility for users

Employees see their signature applied to their message as they type. No second-guessing, no formatting surprises — just effortless assurance that every email sent looks professional and on-brand.

How device deployment works

Connect your mail service

Exclaimer securely connects with Microsoft 365 or Google Workspace, using directory data to automatically keep signatures accurate and up to date.

Configure client-side deployment

In the Exclaimer portal, choose to enable client-side signatures, ensuring they sync directly with user devices.

Deploy the add-in

An Outlook add-in (for Microsoft 365) or a Google Workspace app (for G-Suite) is deployed so signatures can be applied inside users’ email clients.

Sync and apply signatures

Once enabled, the chosen signature templates automatically synchronize to Outlook and Gmail, appearing instantly as users compose their emails.
