Email, Phone & Format Validator
Checks whether a value is well-formed and, for emails and phone numbers, whether it is plausibly real. JSON and IP validation run locally in your browser; email and phone checks use a validation service that can also assess deliverability.

What the Email, Phone & Format Validator does
Format validity and real-world validity are different things. An address can be perfectly formatted and still bounce because the domain has no mail server or the mailbox does not exist — which is why the email check looks beyond the syntax.
