Frequently Asked Questions (FAQ)

What is this email address generator?

A free tool that randomly generates dummy email addresses for testing. It is useful for creating test data (sample email addresses) for development, testing, demos, form and mail-sending checks and seeding databases. Generate any number at once and copy or download as CSV. The domain defaults to the non-existent example.com and similar.

Will mail actually be delivered to the generated addresses?

No. By default it uses example.com / example.net / example.org, which are reserved by RFC 2606. They do not exist and mail to them is never delivered anywhere, so they are safe for testing. All processing runs in your browser and results are never sent to or stored on a server.

Can I specify my own domain?

Yes. Type any domain into the Domain field to generate addresses with it. Note that if you enter a real domain, a result may coincidentally match a real address, so for test sending we recommend a reserved domain such as example.com. You can copy or download as CSV.
