Question: I need a way to recognize and track returning users despite data loss due to Safari ITP and iOS restrictions - do you know of any tools that can help?

Kluvos is an attribution and user recognition system geared for e-commerce businesses. It includes advanced attribution, returning user identification and full customer journey data to help you get a better view of marketing channel performance. Kluvos is designed to bypass Safari ITP limits, offering a better view of customer behavior across devices and marketing channels. It integrates with Klaviyo to boost revenue through better user recognition and full customer journey tracking.

Another option is Hitprobe, which provides browser fingerprinting and threat detection to protect websites from fraud and abuse. Hitprobe identifies repeat visitors and flags suspicious activity, offering a persistent device ID that survives user attempts to be seen as a new visitor. That makes it a good option for reducing chargebacks and improving customer tracking even in privacy-constrained environments.

For e-commerce companies trying to preserve customer tracking and remarketing signals in a privacy-first world, UpStackified is an option. It improves event match quality, lowers CPAs and increases ROAS with PersistentID technology that assigns a unique identifier to website visitors for up to 12 months of recognition. UpStackified uses first-party data and includes features like Session Enrichment and ID Graph, so it's a good option for direct-to-consumer brands trying to get the most out of their marketing.
