Email generator

A test email generator builds addresses in the local@domain shape to fill sign-up forms, database seeds, API mocks and forms while the software is not in production yet. The result on this page is random and stays in your browser: Ontoom does not open an account, host an inbox or forward messages.

These addresses are not inboxes. Nothing you send to example.com, example.org or example.net reaches a person: those names are reserved for examples and documentation and must not be used as real mail. The tool also does not offer temporary email, message reading or a receive API. If the test must receive a confirmation link, use a mailbox you control or your own domain in staging.

The default is example.com. example.org, example.net and any name ending in .test, .example, .invalid or .localhost are also safe choices: those spaces are reserved so they do not work as ordinary sites and mail systems. A custom domain is for when the app requires a specific host, such as the company domain in staging. Confirm that you control that DNS. Addresses at public providers may belong to real people — do not use this tool to generate them in bulk.

The part before the @ changes with the format. Every address is lowercase and without accents, so it pastes into CSV, JSON and databases without encoding issues.

• First and last name produces something like joao.silva@example.com.
• First_last swaps the dot for an underscore: joao_silva@example.com.
• Initial and last name shortens the first name: j.silva@example.com.
• Name and number adds four digits: ana.4821@example.com.
• Random builds a string with no name, useful when the test must not look like a person.

1. Choose the quantity, from 1 to 100.
2. Choose the local-part format: first and last name, underscore, initial, name with a number, or a random string.
3. Keep a test domain or enter a custom domain you control.
4. Click Generate emails and copy one address or the whole list. For a record with a name and documents, use the person generator.

The draw of the name, the number and the chosen domain happens in your browser. Ontoom does not receive the list, does not store the addresses on a server and does not send email. History for this tool, after you generate again, stays in this browser’s local storage and disappears when you clear the site data.

• Use it only in development, QA, staging and study.
• Do not register the address as a real customer contact, invoice, account or production password recovery.
• Prefer reserved domains when the test does not need to receive email.
• Delete fixtures and the local history at the end of the test cycle.
