How we detect SendGrid
We look for sendgrid.net or sendgrid.com addresses in the page, such as tracked links or embedded forms. Sending that only shows in mail headers can't be seen in a page scan.
Detection reads what the page sends to a visitor. A site can hide SendGrid, or use it only on the server, and then we can't see it.
