Random Email Generator

What it does

The Random Email Generator produces synthetic email addresses in realistic naming styles — first.last, firstlast, flast, or random strings — on reserved test domains (example.com, example.org, test.local, or a mix). Generate up to 10,000 per run, seeded so fixture files stay stable.

Common use cases

• Database fixtures — email columns for user tables in dev and staging.
• Form and validation testing — well-formed addresses for the accept path of email validation.
• Import testing — bulk CSV address lists for deduplication and parsing logic.
• UI prototypes — realistic-looking addresses in member lists, inboxes, and share dialogs.

Settings

• Style — first.last, firstlast, flast, or random local parts.
• Domain — example.com, example.org, test.local, or mixed — all reserved or non-routable by design.
• How many — 1 to 10,000 addresses (presets for default, bulk, and random style).
• Seed — identical seed + settings = identical addresses.

Privacy note

Addresses are generated locally in your browser and never uploaded. The domains are reserved for testing (RFC 2606), so mail to them can never reach a real person — the property that makes an accidental “email all users” in staging harmless.

FAQ

Why reserved domains instead of realistic ones? Fixtures leak into staging, and staging sometimes sends mail. Addresses on example.com and test.local are harmless by construction — “realistic” domains eventually spam someone real.

Will these pass email validation? Format-wise, yes. Deliverability checks (MX lookups) will fail for test.local and not deliver for example.* — useful for testing both validation layers.

I need full identities, not just emails. The Fake Profile generator pairs addresses with names, phones, and companies; the Fake User Dataset builds whole tables.
