Stop Publishing Discount Codes On Your Own Site.

Dan, Co-Founder · 11 Jul 2026 · 3 min read

TL;DR: An open code on the homepage gives the discount away without capturing anything. Every offer should cost the visitor an email address.

From the audit vault: From an audit of a condiments brand running a 20% newsletter offer and a separate 10% code printed directly on the homepage: customers could take the discount without ever joining the list.

The double-offer leak

It usually happens by accident: one team ships a pop-up offer, another adds a promo banner, and suddenly the site is handing out codes with no exchange. The customer gets the margin hit either way; the brand only gets an asset back when an email changes hands.

Gate at least one offer

If there is a strategic reason to keep an open offer running, fine, but at least one offer should live behind email capture. Multiple competing offers on a landing page also confuse the buying decision, so consolidating usually lifts conversion on its own.

The audit check

Land on your own site cold, in a private window. List every discount a stranger can reach without typing an email address. Each one is margin spent with nothing captured in return.

Ship this

Never print a live code where a stranger can take it without signing up.

One visible offer per page; gate the rest behind capture.

Audit in a private window: every reachable code is an uncaptured discount.

Give Away Something Big, Not 10% To Everyone
