Synthetic email address generator

Use synthetic addresses for test fixtures, QA forms, demos, and local development. Domains such as example.com and test.org are reserved or clearly non-production choices.

Format options

Format	Example
first.last	`alex.smith@example.com`
first_last	`alex_smith@test.org`
first+number	`alex123@example.com`
random	`alexsmi123@demo.dev`

const email = `${first}.${last}@example.com`;

fake_email = f"{first}_{last}@test.org"

Generated addresses are not mailboxes and should not be used to impersonate people or send messages. Use a controlled test domain for automated systems.
