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 |
|---|---|
| Kit | The vendor’s server blocked or rate-limited our crawler, so this was not measured. |
| MailerLite | The vendor’s server blocked or rate-limited our crawler, so this was not measured. |
| Mailjet | This vendor was not measured because our run stopped waiting for it. |
