CARD.PM vs HiHello Email Signature Manager

CARD.PM is a digital business card service for interactive contact sharing. Cards can contain videos, banners, PDFs, website links, geolocation, social networks, reviews, messaging links, legal notices, and custom text. Sharing works through QR codes, SMS, email, WhatsApp, Signal, Facebook Messenger, AirDrop, LinkedIn, Facebook, and other apps. NFC cards and other physical media can be updated remotely without reprinting. Profiles support multiple scenarios, dynamic PDF and video content, and scan statistics by recipient. VIP mode allows identity-validated contacts to view sensitive details such as a direct mobile number or private documents. Organizations can deploy white-label cards with branding, templates, centralized activation links, and an API for internal tools. The responsive browser app works on smartphones, tablets, PCs, and Macs, with Android and iOS support. The public subscription costs €30 a year per user, includes one digital card, an email signature, an account, and unlimited card changes, and does not renew automatically.

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.
