Identity stitching that runs where your data already lives.

A visitor browses three products anonymously, adds two to a cart and closes the tab. Two days later they sign in from a different network to check out. Without stitching, you get two separate profiles. The abandoned-cart trigger never fires, and the conversion is attributed to a paid channel that did not influence the first session.

With Pipes, the cookie from session one and the email from session two merge into one profile when the login event lands. The abandoned-cart journey fires within seconds, with the original products.

A customer researches on mobile and converts on desktop. Without cross-device identity, the desktop cookie looks like a new prospect. Paid channels retarget a user already 80% through the funnel, attribution credits the last touch, and lookalike models train on duplicates.

With Pipes, both devices link under email_X when the customer authenticates on either. Suppression audiences exclude converters from retargeting pools. Deduplicating cross-device profiles can grow addressable audience size by up to 300x.

A support agent files three customer cases per hour from the same workstation. Each form submission fires an event with the customer's email plus the agent's device ID and cookie. Without identifier limits, every customer handled from that workstation collapses into one profile, corrupting churn scores, LTV and personalization.

Pipes caps email at maxIdentifiers: 2. The first two emails attach to the same profile. The third overflows into a clean new profile, isolated from the workstation's history.
