Email field

Use Email for an email address; it provides email-format validation.

Example: confirmation email

1. In Fields > Contact, select Email.
2. Select the field and open Edit.
3. Set the label to Email address for confirmation and Name to confirmation_email.
4. Set the placeholder to name@example.com.
5. In Validation, retain the email accepted-data format.
6. Turn on Required Field only when you need an address to complete the task.
7. Use Unique Value only for a deliberate one-email-per-submission rule.
8. Set Custom error text to Enter an email address in the format name@example.com.
9. Preview with name@example.com, then with name@.

Format validation does not prove ownership of the mailbox or that it can receive email.
