Frequently Asked Questions
Can this verify if an email exists?
No tool can verify inbox existence without sending an email. This checks syntax and domain validity, catching 90% of input errors.
What is a disposable email?
Temporary inboxes (TempMail, 10MinuteMail) that self-destruct. Often used to bypass registration.
Is my data safe?
Yes, 100%. All validation happens in your browser. We never see or store emails you check.
What is RFC 5322 validation?
RFC 5322 is the official email format standard. Our validator follows it for accurate syntax checking.
