Managing known services#
Known services is a list of domains that belong to well-known internet services, organized by what the service does. Unlike verified domains (which connect a domain to an organization), known service domains describe the type of service a domain provides.
What is a known service domain?#
A known service domain records a domain and the type of service it offers. For example, gmail.com is an "email" service, and cloudflare.com is a "cdn" service.
This list is separate from brands and tags. Brands and tags tell you who operates a service. Known service domains tell you what the service does.

| Domain | Yes | The domain name (for example, gmail.com, sendgrid.net). Must be unique. |
| Service type | Yes | The category of service (for example, "email", "cdn", "hosting", "dns", "security"). |

How known services differ from other features#
