A Nordic retail group connected POS loyalty signup to real-time verification

In-store loyalty captures used to be the worst-quality source. Plugging verification into the POS turned them into the best.

What was breaking

Loyalty signups happened at the point-of-sale across hundreds of stores. Store associates entered email addresses by hand or by reading customer handwriting. Error rates were predictably high. The resulting loyalty list bounced badly enough that the in-store sign-up channel had a negative ROI on email follow-up.

How emailzeno fit the workflow

The POS sign-up flow now calls the emailzeno API in real time. Invalid addresses prompt the associate to confirm with the customer at the till. Disposable addresses are silently flagged. The result: the address that enters the loyalty database is verified before the till receipt prints.

What changed

Loyalty-signup bounce rate fell sharply. The in-store channel became the highest-converting source of loyalty enrolments by lifetime value. Welcome-email open rates from in-store signups reached parity with web signups for the first time.

“Associates used to dread the email field. Now it auto-confirms or auto-fixes, and the awkward "could you spell that" moment is gone.”
