?Frequently Asked Questions
Does it check if the email actually exists?
No — this tool validates the email format and syntax only. Verifying whether an inbox actually exists requires sending a test email or using an MX lookup service.
Can I validate multiple emails at once?
Yes! Switch to Bulk mode and paste a list separated by newlines, commas, or semicolons.
Can I export the valid emails?
Yes — in Bulk mode, click "Copy valid emails" to copy all passing addresses to your clipboard.
