Let’s assume that in your Laravel application, you have a form in which you use a Form Request to validate several fields, including the email.

Generate valid email addresses with Faker
If you are using
Faker to generate fake email addresses, make sure to use

$faker->freeEmail() generates an email address using a list of allowed domains, so we can assume those emails are valid.
