How It Works

What this tool checks

This validator checks that an email address follows correct formatting rules (a username, an @ symbol, and a domain with a valid structure), and flags common typos in popular email domains like gmail.com or yahoo.com.

What this tool doesn't check

This tool checks format only, it does not verify whether the mailbox actually exists or is currently active, since that would require server-side domain and mailbox verification beyond what a browser-based tool can safely or appropriately perform.

Frequently Asked Questions

Does this confirm the email address is real and active?

No, this tool only checks formatting and common typos. It cannot confirm whether a mailbox actually exists or is currently receiving mail.

Is my email address sent anywhere?

No, all checking happens directly in your browser, the email address you enter is never transmitted or stored anywhere.
