Disposable email address
An address on a service built for short-lived use, often with no signup.

In practice
Detection works on the domain: lists of known disposable domains. Unlike a burner, which describes a user’s intent, a disposable address is defined by where it is hosted, and new disposable domains appear all the time.
Verification and sending
ValidReach flags disposable results so you can block them at signup or remove them from a list.
