How does email validation work?

The tool performs multiple checks on each email address: format validation (does it match the standard email pattern), domain format check (is the domain structure valid), TLD validation (does the top-level domain exist and have proper length), and common typo detection (does the domain match known misspellings of popular providers).

Can this tool verify if an email actually exists?

No, this tool validates the format and structure of email addresses, not whether the mailbox actually exists. Verifying actual existence would require sending a verification email or connecting to the mail server, which cannot be done entirely in the browser. The tool catches format errors and typos but cannot confirm that an address is actively receiving mail.

What typos does the tool detect?

The tool detects common misspellings of popular email domains, such as gmial.com (gmail.com), yahooo.com (yahoo.com), hotmal.com (hotmail.com), and many others. It checks against a comprehensive map of known typos for major email providers and suggests the correct domain.

How many emails can I validate at once?

The batch mode can handle hundreds of email addresses at once. The practical limit depends on your browser's memory, but most lists of up to several hundred addresses process instantly. For very large lists (thousands of emails), you may want to process them in batches.

Is my email data sent to a server?

No, all validation happens locally in your browser using JavaScript. Your email addresses are never transmitted to any server. This makes the tool safe for validating sensitive or confidential email lists without risking data exposure.

What makes an email address valid?

A valid email address follows the format local-part@domain.tld. The local part can contain letters, numbers, and certain special characters. The domain must have a valid structure with at least one dot. The TLD must be 2 or more characters. Common issues include missing @ signs, spaces, invalid characters, and missing TLDs.
