HiHello Email Signature Manager vs Sigsync

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.

Sigsync manages email signatures and disclaimers centrally for Microsoft 365 and Exchange. It offers Centralized (Combo), Server, and Client deployment modes. The editor supports drag-and-drop elements, imported HTML, tables, images, social icons, vCards, surveys, and Azure AD fields. Azure AD placeholders can fill signatures with details such as display name, company, job title, department, and profile photo. Server-side signatures work across Outlook, Outlook Web App, Apple Mail, Thunderbird, mobile phones, Macs, and iPhones. Integrations include Office 365, Exchange, Exchange Online connectors, Azure AD, Outlook, and OWA. Marketing tools include promotional banners, scheduled campaigns, analytics, social icons, and CSAT connections with Simplesat and Thermometer. Sigsync states that it uses OAuth 2.0 authentication and TLS encryption, is SOC 2 Type 2 and ISO certified, and complies with GDPR and HIPAA. Licenses are based on users, with no limit on emails sent per licensed user. The monthly plan costs $91 a month; customized pricing is requested for licenses covering more than 200 users. There is a 14-day trial, but no free plan.
