In their own words
Exclaimer
Exclaimer centrally manages employee email signatures and applies legal disclaimers across outgoing messages. It works natively with Microsoft 365, Google Workspace, and Microsoft Exchange. Teams can design signatures with a drag-and-drop editor or start from ready-made templates. Employee names, titles, and numbers can sync from Entra ID, Google Workspace, Okta, and HRIS tools, helping keep signature details current. The service offers server-side imprinting, client-side deployment, and a hybrid option. The Starter plan is $0.90 per user per month, billed annually, and includes one organization-wide template; a 14-day trial is available, but there is no free plan. Standard and Pro add features such as more templates, Brand Kits, scheduling, social feeds, metrics, and HRIS sync. Enterprise pricing is custom. Exclaimer also lists integrations including Workday, UKG Ready, BambooHR, SAP SuccessFactors, ADP Workforce Now, HubSpot, Salesforce, LinkedIn, Facebook, Salesloft, and Outreach. It says organizations with 10 users and above can use the service and offers data-region selection under stated conditions.
HiHello Email Signature Manager
HiHello Email Signature Manager centrally deploys and manages employee email signatures, promotional banners, and disclaimers. It applies signatures to Gmail and Outlook through Google Workspace and Microsoft 365 without requiring end users to set them up. Admins can assign templates by user, department, role, or region and manage layouts, banners, disclaimers, and fields. Marketing teams can schedule, rotate, and retire banners, then track impressions, clicks, and campaign performance with UTM support. Automated signatures are included in Business and Enterprise plans. HiHello lists directory sync and automatic updates, and says it syncs with Microsoft Entra ID, Google Workspace, Okta, and Workday, supports SCIM attribute mapping, and connects with apps through Zapier. The company says messages are signed inside Gmail or Outlook before sending, not routed through external servers, and private DKIM keys are not shared. Personal is free; Business is $5 a month, billed at $60 per user/year. Enterprise pricing is custom and not listed.
