You pick your interests once and decide how many offers you get each week. Everything stops from one place, without writing to anyone.
Audiences are built on real purchase behavior, aggregated across the whole network, not just your store. You never see personal data, only the match.


You run your store. We handle matching, segmentation and distribution.
Brands connect their store. Customers declare their interests and how much they want to receive.
Brand offers meet customer interests. Automatically, with no personal data exposed.
Brands grow with new customers. Customers see only what interests them, within the limit they set.
Net21 matches offers only on consent-given signals. Brands see the match, never personal data.
A cross-brand network for ecommerce. Brands reach new customers who have declared their interests, and customers get only the offers that fit them.
Never personal data. Brands see only the match and the segment, not names, not email addresses, not individual history.
The customer. They choose interests and a weekly limit, and Net21 never exceeds it or sends the same offer twice.
Through the Shopify app, in one click. Products and segments sync automatically, with no code and no migrations.
