Newoldstamp vs Exclaimer

Newoldstamp offers a centralized, cloud-based platform to manage consistent and branded email signatures across your organization. You design a single “master signature template”, and it auto-generates employee signatures with auto-updating capabilities.

You can segment signatures by department, control reply/forward formats, and deploy changes immediately without requiring users to reinstall signatures.

Advanced customization—including templates, social icons, CTAs, disclaimers, and app buttons—is supported, as well as banner campaigns for marketing and analytics tracking like impressions and clicks.

Integrations include Google Workspace, Microsoft 365/Exchange, major email clients, CRMs (e.g., HubSpot, Salesforce), and ESPs

Exclaimer delivers enterprise-grade, centrally managed signature solutions. It supports Microsoft 365, Exchange, and Google Workspace, and features dynamic logic (e.g., internal vs. external, departmental, CRM-driven), banner campaigns, disclaimers, drag-and-drop editor, analytics, role-based access, and directory syncing (Microsoft Entra ID, Google Directory).

Server-side and client-side deployment options are offered, with preview add-ins for Outlook. The platform is SOC II Type 2 and ISO 27001 certified, with 99.99% uptime across Azure data centers.
