About

ContactZapp is a web-based contact synchronization service for people who keep address books in multiple accounts. It synchronizes contacts in both directions across Google Contacts, Microsoft Outlook, Apple iCloud, and CardDAV services, so updates can be reflected across connected personal and work accounts. Users connect their accounts in a browser and continue using their existing contact apps. ContactZapp detects duplicate records within and across accounts. Users can enable automatic merging for clear matches and review uncertain matches before approving them. It encrypts contact data, backs up accounts before its first changes, and keeps a history that lets users undo changes for up to 12 months. The no-cost plan supports up to two connected accounts and 100 contacts; paid plans raise those limits. The service is designed for individuals who want to keep contact information consistent without moving it into a separate contact manager.

About

Sigbot is a cloud-based contact management app that turns email signatures in Outlook and Microsoft 365 into a searchable, shared contact list with names, job titles, companies, phone numbers, email addresses and locations. It scans new mail daily on paid plans and weekly on Free, updates contact details from newer signatures, flags bounced addresses, and sends newsletters and no-reply messages to a review queue. Users can search and filter contacts, organize folders, undo merges, view contacts on a map with radius search, and export to Excel or CSV. iPhone and Android apps sync contacts to a phone's address book for caller identification; iPhone can also label calls without adding contacts. Sigbot supports contact imports, QR and business-card scanning, and shared team folders on team plans. Publisher-verified by Microsoft, it was built for construction teams and also serves other teams whose business contacts arrive by email. A free plan is available.
