Why Exclaimer

One platform. Every signature. Zero effort.

Consistent branding, every email

Signatures are applied server-side, so every message leaves your organisation polished — whatever device, client or settings your staff use.

Dynamic, tailored automatically

Different signatures by department, region, seniority or audience — updated in real time as your directory data changes, with no manual work.

Built-in legal compliance

The correct disclaimers are appended to every outbound email automatically — meeting GDPR, HIPAA and industry rules without relying on memory.

Works with your existing tools

Native integration with Microsoft 365, Google Workspace, Entra ID, Okta, Salesforce and HubSpot — signatures pull live data from your directory.

How it works

Set it once. Never think about it again.

Exclaimer connects to your Microsoft 365 or Google Workspace tenant and applies the right signature to every outbound email automatically. When a job title changes in your HR system, the signature updates immediately. When you launch a campaign banner, it rolls out to everyone in minutes.

FAQ

Exclaimer, answered.

What is Exclaimer?

Exclaimer is a cloud-based email signature management platform trusted by over 80,000 businesses worldwide. It lets you centrally control every email signature across your organisation — ensuring consistent branding, legal compliance, and professional presentation on every message sent.

Does Exclaimer work with Microsoft 365 and Google Workspace?

Yes — Exclaimer integrates natively with both Microsoft 365 and Google Workspace. Signatures are applied server-side before delivery, so every email looks right regardless of the device or client your staff use.

How long does it take to set up?

Most organisations are fully set up within an hour. Exclaimer connects directly to your directory (Microsoft Entra ID, Google Workspace, Okta, or HRIS) and pulls employee data automatically — no manual entry required.

Can we show different signatures for different teams or regions?

Absolutely. Exclaimer's dynamic rules engine lets you tailor signatures by department, region, seniority, audience (internal vs external), and even CRM data from Salesforce or HubSpot — all managed centrally.

How does Exclaimer help with legal compliance?

Exclaimer automatically appends the correct legal disclaimers to every outbound email based on intelligent rules. This helps you meet GDPR, HIPAA, and industry-specific requirements without relying on staff to remember.

What support do you provide after setup?

We handle the full implementation — connecting your directory, designing your signature templates, and configuring your rules. After go-live, we remain on hand for ongoing changes, new template designs, and any technical support you need.
