Test Email Generator — Dummy Addresses for Fixtures

Generate synthetic email addresses on IANA-reserved domains for databases, fixtures, and form tests. They are not mailboxes and cannot receive mail.

Test email addresses — developer notes
Reserved-domain dummy addresses for fixtures and DB seed. Default output cannot receive mail. This is not an inbox.

How generation works

Pick a quantity (1–100), reserved (or owned) domain, local-part style, name locale, and plus-tag. Changing an option refreshes the list immediately. Copy all or download JSON, CSV, SQL, or TXT.

Options

Quantity (1–100)
How many rows to emit for seed jobs. Capped at 100.
Domain
Right-hand side of @. Defaults to example.com (IANA-reserved). {org}.example presets (acme, northwind) live here. Custom reveals a hostname field; consumer ISPs are blocked.
Local-part style
How the left-hand side is built: first.last, first_last, flast (initial + last), sequential (user-001), or random alphanumeric.
Name locale
Which name list feeds person-looking styles (jean.dupont vs john.smith vs hans.mueller). No effect on sequential or random besides remaining documented.
Plus tag (+NNN)
Appends RFC 5233 subaddress +001…+100 so each row is unique without looking like noise. Default off.

Examples

Default fixtures

Settings

domain=example.com, localPart=first.last, plusTag=off

Sample output

Sequential users on mail.test

Settings

domain=mail.test, localPart=sequential, plusTag=off

Test email FAQ

Fixtures, reserved domains, and what this tool is not

Can these addresses receive mail?

No. They are dummy strings for fixtures and tests. They are not mailboxes, not temp-mail, and not an inbox.

Why reserved domains?

IANA reserves example.com, .test, and .example so generated addresses do not land in a real inbox. That is the safe default for DB seed and form QA.

Can I type gmail.com?

No. Consumer mailbox providers are blocked so we never mint addresses that may belong to real people. Use a reserved name or a domain you own (Mailpit, staging, qa.internal.test).

I searched for a fake email generator. Is this it?

If you need dummy addresses for development and fixtures, yes. If you need an inbox that receives the code, this tool will not do that — and we will not add it. Use a mail catcher such as MailHog or Mailpit in your stack.
