Question 1

Are these email addresses real?

Accepted Answer

No. They are randomly generated and do not belong to anyone by design. Use them only for QA testing, form filling, mockups, dummy database rows and similar non-production scenarios. Do not use them to sign up for real services you cannot control.

Question 2

Can I use a custom domain?

Accepted Answer

Yes. Type any domain you like (e.g. example.test or yourcompany.dev) and every generated email will use it. For tests you can also use reserved test domains like example.com or .test which never resolve to real inboxes.

Question 3

Can I generate unique emails only?

Accepted Answer

Yes. Toggle the "Unique only" option to deduplicate the output, ensuring each email appears at most once even across multiple generations.

Question 4

Is anything sent to a server?

Accepted Answer

No. All generation happens entirely in your browser using JavaScript. No emails or settings are transmitted anywhere.
