Comparison summary

Most material score differences

These are the stored dimension rationales returned with each score. They explain the buyer conditions behind the gap without speculating about hidden model reasoning.

Follow-up reliability

24 pts

ContactsFlow · 44/100: AI-generated email summaries stored as contact notes give users reference material they may consult before outreach, leaving scheduling and tracking of follow-ups to external processes.
Sansan · 68/100: Sansan supports targeted contact lists and engagement tracking, which can help teams manage follow-up, but the facts do not establish automated sequencing or a bidirectional Outlook sync, so follow-up support is useful but bounded.

Search and segmentation

23 pts

ContactsFlow · 53/100: Contact list organization is supported, but advanced search filters and segmentation capabilities are not detailed in the product facts.
Sansan · 76/100: Sansan’s targeted contact lists and company-oriented database support segmentation and retrieval for outreach, while CSV export gives an additional way to work with selected records; the facts do not establish full advanced search breadth beyond those functions.

Import, export, and sync quality

15 pts

ContactsFlow · 78/100: The product supports two-way synchronization with Google Workspace, Outlook, iPhone, and Android, which can reduce manual copying between systems, but the facts do not establish export formats, sync latency, or sync error handling.
Sansan · 63/100: Sansan supports CSV contact import and export and offers optional Outlook and Salesforce integrations, but Outlook sync is one-way and every 30 minutes, so interoperability is present while synchronization depth remains limited.

Cons	Paid Teams and Business price states require direct confirmation because the current pricing page presents multiple per-user monthly amounts without a public billing-state binding.

The Gmail AI updater is described as extracting contact information from email content or signatures	Numeric pricing and total implementation cost are not publicly stated. A minimum of 10 users and a standard one-year term are stated. Initial digitization, optional features, scanner sets, SAML, Outlook sync, and Salesforce integration may add cost.
Contact organization quality	83The Business plan supports directory management and unlimited custom fields, though lower editions are more restricted or limit contact capacity.	88A company-wide business-card and contact database with organization trees and relationship visibility lets teams maintain a single governed view of accounts and people, which directly supports large-scale contact organization.
Interaction history and context	67AI-assisted contact summaries can be saved as contact notes from emails, but standard usage is constrained by plan-specific limits on AI credits.	80Tracks email, call, meeting, and sales histories alongside Salesforce opportunity data, but the Contact Inbox signature extraction tool is limited to Gmail and Exchange Online within Japan.
Contact data hygiene	82Automatic duplicate removal together with AI-assisted contact updates and enrichment supports cleaner shared records, and Business edition adds unlimited backup for recovery.	86Automatic and manual duplicate combination together with AI-assisted and human-verified card digitization give buyers concrete tools to keep contact records consistent as volume increases.
