Exclaimer is a software company that specializes in email signature management and branding for organizations. Its solutions are designed to apply consistent signatures, legal disclaimers, and marketing banners to outgoing email across corporate mail systems, helping preserve brand integrity and regulatory compliance.

Products and platforms: Exclaimer offers signature management products for cloud-based and on-premises mail systems, including editions for Microsoft 365 and Microsoft Exchange Server.

Deployments can be cloud-based or integrated into existing mail infrastructure to render signatures at the point of sending.

Features: The offerings include template-based signatures with company logos, banners, and legal disclaimers. Signatures can be personalized by pulling user attributes (name, job title, department) from directory services. The system supports policy-driven rendering to apply signatures based on user attributes or group membership, along with branding controls and analytics. Deployment options cover server-side and client-side approaches, with compatibility across major mail platforms.

History and market position: Exclaimer is a United Kingdom-based company founded in 2001. It has served global customers across industries, providing scalable solutions for mid-sized businesses and enterprises seeking consistent email branding and regulatory compliance across multiple mail environments.
