Why Enterprise companies choose Exclaimer

Consistency without compromise

Easily control the branding of every employee email signature from one central platform. Whether you’re managing one office, or a global workforce, updates take effect automatically to keep every email on-brand.

Exclaimer supports directory sync via Entra ID, Google Directory, Okta, or your preferred HRIS, ensuring accurate employee details such as titles, departments, and contact information across every signature, without manual updates.

With role-based access control (RBAC), your team can focus on the tasks that each team does best. IT retains centralized control of the platform’s setup, compliance, and security, while Marketing can take charge of campaigns that increase email signature engagement.

Advanced Signature Rules let you decide exactly which signature (or disclaimer) is applied, and when. Whether you need different templates for departments, regions, or seniority levels, you can be sure every email contains the correct signature automatically.

You’re in safe hands

We’re the proud holders of multiple industry certifications for our security and compliance standards.

Seamless integration with your email platform

Centrally manage email signatures across Microsoft 365, Google Workspace, and Microsoft Exchange.

Enterprise email signatures simplified

Keep disclaimers under control

Disclaimers are applied automatically based on geography, department, or business unit, so you can maintain the peace of mind that every email carries the correct compliance message, without relying on employees to add them manually.

From regional offices to sub-brands, it’s easy to roll out the correct template everywhere. Signature Rules ensure consistent branding across markets, languages, and business units, even during rebrands or mergers.

Managing multiple teams, regions, or business units doesn’t have to be complicated. Exclaimer syncs with your directory to automatically assign the right signature to the right people or your groups, without any manual updates.

New hires start with a compliant, professional signature from day one. Exclaimer pulls details directly from your active directory or preferred HRIS, ensuring employees can hit the ground running, with no extra work for IT.
