Visitor ID category exploded 2025-2026. Running multiple tools for different use cases.

RB2B for US-only person-level identification on /pricing page visitors. $129/month.

Koala for visitor + product usage combined (we have PLG signup flow). Modern UI. Strong Slack alerts.

Warmly evaluated — visitor ID + auto-outbound integrated. Auto-outbound quality variable.

Workflow. Visitor identified on /pricing or /features → Slack alert → SDR triggers cold email via pre-warmed inboxes from PuzzleInbox + Smartlead within 5 minutes. Reply rates 3-5x higher than blind cold outreach.
