What matters.

Exclaimer is an established global vendor for email signatures with long market presence and tight Microsoft 365 integration. Conbool Disclaimer is a German alternative with EU hosting and signature management as part of a broader email security platform. Which fits depends on your hosting requirement, integration with other email security modules and licensing preference.

The five most common questions, side by side.

Every statement about Exclaimer links to a public source. Every Conbool claim is verifiable in a demo.

Where is my data hosted?

Conbool Disclaimer

Exclusively in EU data centres on ISO 27001-certified infrastructure. Contract party and data processor is Conbool GmbH in Germany. The data location is named in the DPA.

ExclaimerExclaimer

Exclaimer operates multiple global cloud regions according to the vendor, including Europe and North America. Which region is active for your tenant is governed by the contract.

Source: exclaimer.com — Trust Center / Data Hosting. Please confirm the concrete location with the vendor.

Why it matters: If the central signature solution also processes personal data (name, photo, role), the data location matters for GDPR records of processing.

How is the signature technically applied?

Conbool Disclaimer

Server-side in the mail flow: the signature is created at send time. Endpoints need neither add-ins nor local templates. Outlook desktop, web and mobile look identical.

ExclaimerExclaimer

Exclaimer traditionally uses a cloud connector in the Microsoft 365 mail flow or a client-side add-in. Both methods are documented; pros/cons (live preview vs. consistency) depend on the method.

Source: exclaimer.com — signature management feature description.

Why it matters: Server-side protects against user manipulation and guarantees consistency; client-side offers live preview. Which fits depends on culture and compliance.

How is licensing structured?

Conbool Disclaimer

Modular per feature — you can activate Disclaimer alone or together with MailGuard, SecureMail and SecureFiles. Term monthly or yearly.

ExclaimerExclaimer

Exclaimer Cloud is licensed per mailbox per year. Editions (e.g. Pro, Enterprise) define scope. Terms are negotiated by the vendor.

Source: exclaimer.com — Pricing / Editions.

Why it matters: If you want Disclaimer combined with other email security functions, the modular Conbool bundle helps. If you only need signature management, Exclaimer is a focused specialist.

How do marketing campaigns and tracking work?

Conbool Disclaimer

Marketing banners with expiry date, audience filter (department, country, recipient domain) and A/B test. Tracking runs cookie-free server-side — click and conversion rates are captured GDPR-compliant.

ExclaimerExclaimer

Exclaimer also offers banner campaigns with targeting and click tracking. Which tracking is active depends on the edition and privacy settings.

Source: exclaimer.com — Campaigns / Banner Marketing feature description.

Why it matters: Marketing wants reach, data protection wants compliance. A cookie-free server-tracked solution is usually the smallest common denominator.

How does the solution integrate with AD and HR?

Conbool Disclaimer

Sync with Active Directory, Entra ID and HR systems (Personio, Workday) by default. On role, location or function change the signature updates automatically — no PowerShell, no scripts.

ExclaimerExclaimer

Exclaimer integrates with Microsoft Entra ID and Active Directory; HR integrations are available via connectors or Microsoft Graph. The current connector list governs what's available.

Source: exclaimer.com — Integrations / connector list.

Why it matters: Manual signature maintenance is the #1 error source. Clean AD/HR integration saves IT tickets and keeps signatures current.

Migration checklist

What to watch for when migrating away from Exclaimer.

Replacing Exclaimer typically runs in four steps — focused on template export and parallel banner migration.

  1. 1. Export current Exclaimer templates

    Export all active signature templates, banner sets and targeting rules from the Exclaimer portal. They serve as a blueprint for Conbool templates and save redesigning.

  2. 2. Consolidate AD and HR data sources

    Clarify where name, role, phone and photo come from in your signature. Conbool syncs directly with AD / Entra ID / HR. If Exclaimer uses its own data store, plan a data-source migration.

  3. 3. Switch the mail-flow connector

    Exclaimer Cloud typically uses a connector in M365. It is replaced by the Conbool connector. In the transition (max. 14 days) both may be active, but only one with an active signature rule — otherwise double signatures.

  4. 4. Synchronise marketing banner campaigns

    Existing banner campaigns are exported with click statistics (CSV) and recreated in Conbool as templates. This way historical performance comparisons are preserved.

For large tenant migrations a pilot phase with 1–2 departments is recommended before broad rollout. Double signatures are the most common migration problem and avoidable.
