Are these random emails real?

No. The addresses are syntactically valid but not registered to any mailbox. Use them for test fixtures, mock data, UI screenshots, demo videos, and database seeding — anywhere you need an address that looks correct without belonging to a real person.

Can I use these to sign up for services?

Don't. These addresses don't have a mailbox behind them, so you'll never receive a confirmation, password reset, or receipt. If you need a real inbox you don't want to give out, use Gmail's plus-aliases, a privacy alias service (SimpleLogin, DuckDuckGo Email Protection, Apple Hide My Email), or a temp-mail service that gives you a real, short-lived inbox.

How many can I generate at once?

Up to 200 per batch. Set the count, hit regenerate, and the entire batch appears instantly. You can export to CSV and run as many batches as you need — there's no daily limit.

What are the different style options?

Realistic names produces patterns like first.last and first_last with believable Western first and surname pairs. Username style produces adjective+noun handles like swiftfox123. Throwaway produces random lowercase strings, ideal for stress-testing form validation. Business produces clean first.last addresses for professional-looking mock data.

Does it work with my own domain?

Yes. Choose "Custom domain" and type any domain — yourcompany.test, qa.local, anything. Every generated address will use that domain.

Is the data really random?

Generation uses a seeded pseudo-random generator (mulberry32). Every time you hit regenerate, a fresh seed is used, so each batch is different. Output is deterministic for a given seed, which is helpful if you ever need reproducible test fixtures.

What is a random email generator used for?

The same tool covers five very different jobs. Here's where it earns its keep.

Test data for sign-up forms and APIs

Anyone writing automated tests for an account-creation flow needs a steady stream of fresh, valid-looking email addresses. Hard-coding one breaks the second your test runs twice, because the email is now "already registered." A random email generator solves this in one shot: regenerate before each test, feed the address into your Cypress, Playwright, or Postman script, and your sign-up flow sees a fresh user every time. Pair the CSV export with a CI step that loads fixtures, and you have repeatable test runs without maintaining a hand-curated list.

Mock data for design, prototypes, and demos

Realistic-looking user lists make a prototype feel real. Spreadsheets, dashboards, CRM screens, admin tables — anywhere you need to show what the product will look like populated, an email column with first.last patterns will look at home. The "realistic" style pulls from a curated pool of first names and surnames so the output reads naturally; nothing tips the viewer off that the data is generated. Drop the CSV into a Figma plugin, a Notion table, or a Google Sheet and your screenshots instantly look production-ready.

Database seeding for development

Local dev environments need users to be useful. Most teams keep a small set of hand-typed accounts, which is fine until you're testing pagination, search ranking, or anything that depends on scale. Generate 200 random emails, pipe them into your seed script, and your dev database has a credible user table in seconds. Because the generator uses a deterministic seed, you can reproduce the same seed set across machines — useful when sharing a fixture with a teammate.

Stress-testing email validation

If you've written a regex or a validation library for email addresses, you know there are a thousand edge cases. The throwaway style produces lowercase character strings of varying lengths, useful for fuzzing your validator. The realistic style produces addresses with dots, underscores, and digits — exactly the characters that trip up naïve regex. Run a batch through your validator and watch where it breaks.

Privacy-conscious placeholders

When you're writing documentation, blog posts, or screenshots, you don't want to use a real email address — yours or anyone else's. A random one looks more authentic than someone@example.com and removes the risk of accidentally exposing a real contact. For documentation that needs to feel real, but mustn't be, this is the path of least resistance.
