Amazon CAC

You pay Amazon to acquire the same customer again and again.

On Amazon, every reorder is a fresh paid acquisition — because you never captured the buyer the first time. Ovnit turns anonymous Amazon buyers into owned customers, so your next sale to them is free.

3 × CAC Three purchases from one household, three paid acquisitions. You never met them.
1 × CAC Capture the owner on purchase one. Purchases two and three arrive from your own email.
The Amazon tax

Anonymous buyers = permanent CAC

Amazon keeps the customer relationship. With no email and no consent, the only way to reach that buyer again is another Sponsored Products click or a deal — you re-pay CAC on every single repeat purchase, forever.

The Ovnit effect

Own the buyer, and CAC collapses

A QR on the pack captures the owner's email and consent. Now reorders come from your email/SMS — at near-zero marginal cost — and your paid Amazon spend goes to new customers, not recapturing old ones.

Better offline signal also lowers paid CAC.

Every captured owner is a conversion you can feed back to Meta, Google and TikTok. The algorithms finally see who actually buys on Amazon — so targeting, bidding and delivery sharpen, and blended CAC drops even on the paid side.

How it works
1

Capture the Amazon buyer

A branded QR on packaging opens a companion page; the owner registers for the warranty / digital manual and (separately) opts in to marketing.

2

Reorders move to owned channels

Timed reorder reminders and cross-sell go out over your own email/SMS — no Amazon click required, so repeat CAC approaches zero.

3

Feed conversions back to ad platforms

Push captured owners to Meta / Google / TikTok via the activation webhook, so paid acquisition of new customers gets more efficient too.

See the flip side: lifetime value.

Lower CAC is only half the equation — the owners you capture also carry a measurable, compounding LTV. Model it for your own numbers.
