Software testing is a crucial part of the software development process, as it helps in validating the software’s functionality and ensuring that it is working as expected. The testing process is a tedious and time-consuming because the production-like environment needs to be simulated to evaluate the app’s performance.
Testers use .test email domain to test and validate email-related functionalities. Workflows like registration confirmation, password resets, and notifications can be tested without sending real emails.
If you want to create a .test email address, then you cannot create an email address with such a domain extension. The .test domain name is reserved exclusively for testing and development and is not available for registration or use on the public internet.
It is designed to serve as an alternative to test webpages using the default localhost, and hence, is guaranteed never to be registered on the Internet. However, if you want to create a custom email address for free, then Neo has a solution.

Understanding .test Email Address
The .test is a top-level domain that is reserved for use in examples, documentation, or testing. However, it is not meant for use in internet production.
The Internet Engineering Task Force (IETF) reserved this domain name in RFC 2606 (June 1999), and it is not meant to be added to the Internet's global Domain Name System (DNS). Because the test and its subdomains cannot be registered, they can be used for testing without worry of conflicting with existing or potential domain names.
Developers and testers configure their local or development environments to recognize .test domains internally. For example, your application or test suite can generate or accept email addresses like user@example.test for testing email workflows without sending actual emails externally.
You set up tools or software (like local mail servers, mocks, or email capture tools) to handle .test emails safely without delivering them outside the test environment.
Here’s where the .test domain can be used:
- Developers use .test email addresses (e.g., user@example.test) to simulate user accounts during software testing. It avoids accidentally sending real emails during QA or staging tests.
- It is perfect for writing and running automated tests involving user registration, login, password reset flows, etc., without interacting with actual email servers.
- It is also used with continuous integration/deployment pipelines to test features safely without needing a live domain or third-party email provider.
