THE PROBLEM

One checkbox for every shopper leaves subscribers on the table

Same words, every region

Shopify applies one consent setting to your entire customer base, no matter where each shopper is checking out from.

Opt-ins left behind

A default that has to work for everyone is the strongest ask for no one. Every missed opt-in is a customer you pay to reach again later.

Change it, and the proof is on you

Move off the default and you need to show exactly how each consent was obtained. Most teams don't have the records to do it.

THE SOLUTION

The strongest opt-in each shopper can be shown

Three steps, set up once. No work required from your end.

1

Install in five minutes

Add the Consent Optimizer checkout extension. No theme edits, no developers, nothing to configure.

2

Every shopper gets the right ask

We identify each shopper's location and serve the most assertive opt-in that is compliant there, from UX to wording.

3

Subscribers land in Klaviyo

New subscribers sync straight to Klaviyo with a full consent record, while a control group proves the lift.
