How it works

Know before you submit

Every retail media network has different specs. We check your creative against all of them in one call, so you launch on the first try. Not the third.

Why every network rejects differently

11Retail media networks

Different dimensions, file sizes, formats. And rules that aren’t written down anywhere.

50+Unique placements

A single network can have a dozen placements, each with different rules. Amazon alone has 8.

15–30%First-submission rejection rate

Most creative teams are guessing. Guessing wrong costs days of back-and-forth.

$200–500Cost per rejection

Designer time, campaign delays, missed launch windows.

Under the hood

We track the rules so you don’t have to

Official + undocumented

We start with published spec sheets, then add rules learned from real rejection feedback. Some rules aren’t written down anywhere.

Updated continuously

Networks change specs without notice. We watch for changes so you don’t have to read another changelog.

Confidence-scored

Every rule has a confidence level based on its source. You can see how certain we are about each one.
