Published
The actual list is published, not just a promise to keep one.
None of the vendors we measured here published this.
No subprocessor list found.
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.

Not measured
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.
| Vendor | What we found |
|---|---|
| Bluehost Mail | The vendor’s server blocked or rate-limited our crawler, so this was not measured. |
| Rackspace | The vendor’s robots.txt excludes us from at least one of these addresses, so this was not measured. |
