Use Cases
Frequently Asked Questions
- How can I create many test email addresses at once?
- Set a count up to 100, pick a domain, and click Generate. Each address gets a unique 10-character random local part from the browser's cryptographic source, the batch is deduplicated automatically, and you can copy the whole list or download it as a CSV — all locally, with no signup.
- Do bulk-generated temp addresses actually receive mail?
- No — and this tool says so on purpose. It produces fixture data: well-formed addresses on the reserved example.com/org/net domains (RFC 2606), which are guaranteed never to receive mail, with no inbox created anywhere. If your test needs to actually receive a message, use our Email Address Generator, which mints one real working inbox at a time.
- How do QA teams test signup flows without real inboxes?
- In two layers. For form validation, database seeding and load tests, fixture addresses like these are enough — valid format, unique, importable as CSV. For end-to-end tests where the verification email must really arrive, teams switch to a live disposable inbox for that final step.
- Is it allowed to create multiple accounts with temporary emails?
- That depends on each service's terms — many prohibit multiple accounts per person regardless of which email you use. These fixture addresses are intended for your own systems: test databases, staging environments and load tests, where no third party's terms are involved.
- What format should test email fixture data be in (CSV vs JSON)?
- CSV is the safest interchange format — every test framework, spreadsheet and database importer reads it, which is why the download here is a single-column CSV with a header row. If your harness wants JSON, pasting the copied list into an array takes seconds.
