Is there any tool that can validate an email ? Like the email entered should be valid and existing. (More than regex). It should be an actual email. (Should work with either front-end or backend (React Native/React or Php laravel)) If this can be done without sending verification email ? Thank You.

the only guaranteed method is to actually send an email

You can only validate that an email address is of the correct form. Whether the email exists on the said mail server and is indeed under the control of a user can only be verified by sending a confirmation email https://datatracker.ietf.org/doc/html/rfc2822#section-3.4.1
