Disposable Email Checker
Check whether an email address uses a known disposable or temporary email domain, using a built-in list. A basic list check, not a live database. Free, fast and private.
Honest note: this checks the domain against a built-in list of well-known disposable email providers. It is not a live database, so a new or uncommon throwaway service may not be listed.
How to use Disposable Email Checker
- Enter the full email address you want to check.
- Click Check Email.
- Read whether its domain is on the built-in disposable list.
Basic list check only: compares the domain with a built-in list of known disposable providers. It is not a live database.
