Amazon
UngradedWe have observed one machine fact about Amazon's mail. That is all this page claims.
Observed: this sampled message carries an RFC 8058 one-click unsubscribe signal. That observation alone does not establish recipient-provider scope, DKIM conformance, endpoint safety, or sender honor.
Route header present: yes · RFC 8058 one-click: yes · as of 2026-07-09
This is CAPABILITY, not honour — it means their mail offers a machine exit, NOT that they act on it. A sender can ship a perfect one-click header and still ignore every request it sends. Amazon has not been graded yet.
Caveat, verbatim from the data export:
CAPABILITY, not honor: a true value means observed mail from this domain carried the route/one-click header. It says nothing about whether the sender honors it. A floor, not a census.
Where this came from
Source: gmail_threads route cache (server-persisted at deck-save; consent-scoped, reaped on disconnect). It is a sender-level boolean — a domain either has been seen sending mail with an exit route, or it has not. It contains no counts, no per-person data, and nothing about you.
What it cannot tell us is the only thing that matters: what happens when you actually click. That takes a crawl, and a crawl is what earns a grade.
What a grade would require
Nothing is published about Amazon until we have walked their unsubscribe flow ourselves: at least 3 probes spread across at least 48 hours, each with the raw List-Unsubscribe header, a step-by-step crawl log and a screenshot per step. Below that bar the answer is ungraded, never a guess. Read the full method.
