Not subprocessors
- Instantly and Smartlead: accounts you connect yourself. We call their APIs with the key you give us, to read and, if you turn write-back on, to clean the campaign you choose.
- The mail servers we check: to verify an address we connect to the recipient’s own mail server. That is the service you are asking us to run, not a vendor working for us.
- Cloudflare DNS-over-HTTPS: used by the Chrome extension inside your browser, not by our servers. See the extension privacy page.
Changes
We update this page before we add a provider that will process customer personal data. There is no email notification list yet. If your agreement requires advance notice of new subprocessors, write to support@simpleverifier.com and we will agree how to do it. See also the DPA and the security page.
