No third-party tracking before consent in Transactional email and notifications
We load their front page and count third-party requests before anything is clicked.
3 of 32 companies we measured here publish it, that is 9%. Last checked 2026-10-18.
9% here against 6% across every category we measure. Transactional email and notifications sits above the overall share for this criterion.
This page counts companies, not product entries: a company with two products in this category is one company here and two rows below.
