Anonymous User Detection
Nitro × Updatrr
Identify anonymous visitors by phone number. Recover them on WhatsApp before they ever abandon.
About this integration
Nitro identifies anonymous Shopify visitors by matching their session to a known phone number — typically before they've added anything to cart. When Updatrr receives this data, it fires a personalised WhatsApp message at exactly the right moment, turning anonymous traffic into recoverable revenue.
Nitro resolves the phone number behind an anonymous browsing session. This data is sent to Updatrr via webhook. Updatrr checks the contact's browse history, determines if they've viewed a product or category, and sends a contextual WhatsApp message — for example, 'We saw you checking out our [Product Name] collection. Want 10% off?'
What you get
- ✓Reach anonymous visitors before they add to cart
- ✓Higher intent signals — intervene at the browse stage
- ✓Personalised WhatsApp messages with product context

Frequently asked questions

- Match rates typically range from 10–25% of anonymous sessions, depending on traffic source and region.
- Can I suppress users who bought in the last 30 days?
