Our verdict on Exclaimer
Exclaimer centralizes email signature management for organizations using Microsoft 365, Google Workspace, or Microsoft Exchange. It supports server-side, client-side, and hybrid deployment, with signatures applied across desktop, web, mobile, and other supported mail clients. Administrators can use a drag-and-drop designer, legal disclaimers, employee-detail synchronization, and rules based on senders, recipients, departments, and dates. That makes it a strong fit for large organizations that need consistent branding and governance across multiple teams.
Pricing is organized into four tiers, all designed for annual billing where a per-user price is shown. Starter costs $0.90 per user per month and includes one template, centralized signatures, auto-updated employee details, legal disclaimers, and preview. Standard costs $1.45 per user per month, adding unlimited templates, department and team signatures, three Brand Kits, scheduling, and recipient targeting. Pro costs $1.75 per user per month and adds unlimited Brand Kits, advanced scheduling, social media feeds, HubSpot and Salesforce integrations, usage metrics, engagement dashboards, and HRIS synchronization. Enterprise uses custom pricing and adds a Dedicated Customer Success Manager, tailored onboarding, guided implementation, and rollout planning.
Its ecosystem coverage is a major consideration for distributed organizations. Exclaimer connects with Microsoft 365, Google Workspace, Exchange, Outlook, Gmail, Microsoft Entra ID, Google Workspace Directory, Okta Universal Directory, Workday, UKG Ready, BambooHR, SAP SuccessFactors, ADP Workforce Now, HubSpot, and Salesforce. These connections support directory synchronization, employee attributes, CRM workflows, and centralized administration. Choose Exclaimer when governance, deployment flexibility, and organization-wide control matter more than a free entry point. Smaller teams seeking a free plan or simpler signature management may prefer a less tiered tool.
