Frequently asked questions
Without a central system, company email signatures can quickly become inconsistent — outdated logos, missing disclaimers, or non-compliant layouts.
Exclaimer solves this by managing every signature from one place, ensuring brand consistency, compliance, and a professional look across all employees and departments.
Yes. Exclaimer integrates directly with Microsoft 365 and Google Workspace (formerly G Suite).
You can apply signatures server-side (after sending), client-side (as users compose emails), or in a hybrid setup that combines both for maximum flexibility.
Setting up Exclaimer typically depends on the deployment method and the size of your organization. For most organizations, the initial configuration can be completed in about an hour. This includes connecting Exclaimer to your email platform (e.g., Microsoft 365 or Google Workspace), setting up mail flow rules, and creating initial signature templates.
Yes. Exclaimer is built to support organizations of any size — from small teams to enterprises with tens of thousands of users. It handles complex directory structures, multiple domains, and regional signature variations without compromising performance or consistency.
