Notice before subprocessors change in Email marketing

A list is a snapshot. Art. 28(2) GDPR gives you a right to object, and that needs advance notice.

10 of 33 companies we measured here publish it, that is 30%. Last checked 2026-10-18.

30% here against 10% across every category we measure. Email marketing 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.

We reached at least one address for each of these vendors and none of them carried it. That is what we found at the addresses we checked, on the date we checked them, and not a statement about what the vendor has.

We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
