What is the Random Email Generator?
Real-looking emails such as [email protected] make test data and screenshots far more convincing than “[email protected]”. By default we use domains reserved for documentation and testing (RFC 2606), so a message sent by mistake will never land in a stranger’s inbox.
An email address has two parts separated by the @ sign: the local part, which names the mailbox, and the domain, which tells mail servers where to deliver. RFC 2606 reserves example.com, example.net and example.org, along with top-level domains such as .test, .example and .invalid, so documentation and test suites never point at someone’s real inbox. The local part may legally contain dots, plus signs and other symbols, which is why overly strict validation patterns often reject genuine addresses.

Plus addressing and staging inboxes
Many mail providers support “plus addressing”: mail sent to name+anything@domain arrives in the name mailbox. If your staging server catches all mail for a domain you own, combine the Custom domain option with generated addresses to create hundreds of distinct test accounts that all land in one place. Check that your sign-up form accepts the plus sign — some still don’t.
Validation without frustration
The most reliable check is simple: exactly one @, a non-empty local part and a domain containing a dot — followed by a confirmation email, the only real proof that an address works. Complex regular expressions tend to reject valid addresses with long top-level domains or unusual characters. Compare domains case-insensitively, since the domain part is never case-sensitive. Never use generated addresses to sign up for real services in someone else’s name. Press Generate to create a fresh batch of test emails.
Frequently asked questions
Can I receive mail at these addresses?
No. The default domains are reserved and have no mailboxes. If you need a working inbox, use a disposable email service.
Can I use my own domain?
Yes, type it into “Custom domain” — handy when your staging server catches all mail for a domain.
Are the addresses unique?
They are randomised from thousands of combinations; duplicates within one batch are very unlikely.
What is plus addressing?
A feature of many mail providers where anything after a plus sign in the local part is ignored for delivery, so name+test@domain reaches the same mailbox as name@domain.
Which domains are reserved for testing?
RFC 2606 reserves example.com, example.net and example.org, plus the .test, .example, .invalid and .localhost top-level domains.
