What this tool does
Email Generator creates synthetic test email addresses using first.last, initial+last, keyword, or random local-parts with configurable domains and separators.

✉️ Email Generator
Generate fake/test email addresses with flexible formats, domains, separators, count, and seed support.
Why it is useful
It helps developers and QA teams fill signup forms, seed fixtures, and demo UIs without inventing addresses by hand.
How it works
The browser combines name banks or keywords with separators, optional numbers, plus-tags, and a chosen domain to build local-part@domain addresses.
Formats
first.last and initial+last mimic common corporate patterns. Keyword mode is good for role-based demos. Random mode is useful when uniqueness matters more than realism.
Domains
Prefer example.com, test.test, or other reserved/test domains so generated addresses are obviously not production contacts.
Reproducibility
Enter a seed with the same settings to regenerate the same list for shared fixtures.
Privacy note
Email generation happens locally in your browser.
Important limitation
Generated addresses are synthetic. They may collide with real mailboxes if you use public domains—stick to example/test domains for safety.
Quick answers
Which domain should I use?
example.com and test.test are safe choices for documentation and demos. Avoid real consumer domains unless you control delivery.
What is a plus tag?
Some providers treat user+tag@domain as an alias of user@domain. Useful for filtering test signups when a real mailbox is intentionally used.
Can I export the list?
Yes. Copy plain text, copy JSON, or download CSV for spreadsheets and fixtures.
Are results unique?
With Prefer unique enabled, the tool retries within a run. Uniqueness is not guaranteed across separate generations without careful seeding.
Common Use Cases
Fill signup form test cases
Generate first.last emails on example.com to exercise client and server validation without real mailboxes.
Seed demo user fixtures
Use a fixed seed and JSON export so every environment loads the same synthetic accounts.
Create role-based QA addresses
Switch to keyword format with demo/qa/staging tags for readable addresses in test reports.
Stress uniqueness constraints
Generate a larger random set and import CSV to check uniqueness rules and conflict handling.
