Disposable Email for Developers and Testing
Anyone testing sign-up, double opt-in or password reset needs many fresh addresses. With Mail4Free.net you have them in seconds - without setting up mailboxes of your own.
Why use a disposable address?
- Every test run gets a fresh, empty address.
- Self-chosen names make test cases easy to trace.
- Codes and links are detected - saving you from digging through mail bodies.
How it works with Mail4Free.net
- Pick an address with a name that fits the test case.
- Trigger the sign-up in your application.
- Check the incoming mail in the inbox: subject, sender, code and link.
Good to know
Use disposable addresses only for test and development environments, not for production accounts or real customer data.

Is there an API for automated tests?
Not at the moment. The inbox can be used in the browser; for automated tests, mails can be exported as .eml.
How long are test mails kept?
Temporary addresses expire after the configured lifetime, together with their mails. For longer tests a permanent address helps.
