What this ESP allows
Catalog shared by both pages. Each note carries its source, its date, and its confidence level.
On the right, what our emails say about it: matching, contradicted, never observed despite the volume, too few emails to conclude — or out of reach, when the capability can't be read from an email.

Limits of this analysis
It doesn't say what a brand has actually configured. A sending platform that allows turning off the pixel says nothing about which brands have done so — that's what a brand's report answers.
It doesn't rank. No score, no recommendation: capabilities don't carry the same weight depending on the use, and that weight isn't ours to set.
A “not checked” cell is not a “no”. It says nobody has gone to look yet, and nothing else.
The corpus does not establish a capability. A rate of observed pixels says what brands send, not what the tool can do.

Does Iterable rewrite links for click tracking?
Do your emails go through Iterable?
The sending platform is read from the headers, not from a claim. The report names it, and says where to fix the findings with that vendor.
