Disposable email: inspect the evidence

A disposable email address uses a domain identified as temporary or disposable by an applicable dataset. This classification does not prove that a person is fraudulent or that a mailbox is technically invalid. Useful reporting records the evidence and avoids claiming that domains outside the assessed dataset were conclusively cleared.

Key points

A flag is not an identity judgment.
Datasets change.
Not assessed does not mean no.

Detailed explanation

Temporary services can rotate domains and legitimate users may prefer privacy addresses. Decide how to handle the signal according to your workflow.

Example

A form could ask for another contact address rather than declaring a temporary-domain flag proves abuse.

How RefreshList handles it

This release does not claim a comprehensive disposable dataset. Live findings require supported provider evidence.

Limitations

Sample domains are not a current blocklist or evidence about a real address.

Methodology and sources

Product behavior is described from the current RefreshList implementation and provider contract. Protocol context should be checked against the applicable standards and provider documentation. This page does not create a benchmark or certification.
