Email Validator

NewText

Paste one or many email addresses and check their format, top-level domain and role-based prefixes in one pass. The validation is fully client-side and private.

Email addresses (separate by comma or new line)

This checks format and top-level domain only. It cannot confirm that an address exists in a mailbox or that mail is received.

What does this validator check?

It checks the format (name@domain.tld), that the top-level domain is a real and common one, and whether the local part looks role-based such as info@ or admin@.

Can it prove an email exists?

No. A server-side check would be needed to confirm a mailbox exists, and this tool stays fully private and local.
