What it does
Email Validator checks whether email addresses are correctly formed and deliverable — free, right in your browser, with no sign-up required. Paste one address or a whole list (comma-, space-, or semicolon-separated), and the tool runs a thorough syntax check: exactly one @ sign, a valid local part and domain, a proper TLD, no spaces, and no illegal characters. It then looks up the domain's MX records to confirm the mail server actually exists. On top of that, a built-in typo engine detects the most common mistakes — gmial.com → gmail.com, hotnail.com → hotmail.com, .con → .com — and suggests the likely correction. Every check runs on your device; your email addresses are never sent to any external server.
How to use the Email Validator
- Type or paste one email address — or a list separated by commas, spaces, or semicolons — into the input field.
- The tool instantly checks the syntax of each address: the @ sign, local part, domain format, and TLD.
- For valid addresses, an MX lookup confirms the domain's mail server actually exists and can receive email.
- If a common typo is detected (such as gmial.com instead of gmail.com), the tool shows a suggested correction you can apply with one click.
Frequently asked questions
- Does a "valid" result guarantee the email address exists and belongs to a real person?
- No. The tool confirms the address is correctly formed and that the domain has a working mail server (MX record). It cannot verify whether a specific mailbox exists without attempting to send an email, which this tool does not do.
- What typos can the tool detect and fix?
- The built-in typo engine catches the most common provider misspellings (gmial, gmai, gmaill, gnail, gamil → gmail; hotnail, hotmial → hotmail; yaho, yahooo → yahoo; outlok, outloo → outlook) and mistyped TLDs (.con, .cmo, .ocm → .com; .nte → .net; .rog, .ogr → .org).
- Are my email addresses sent to any server?
- The syntax and typo checks run entirely in your browser. The MX lookup makes a DNS query to verify the domain's mail server — this query contains only the domain name, never the full email address or local part.
- Can I validate a list of addresses at once?
- Yes. Paste a list separated by commas, semicolons, spaces, or one address per line. The tool deduplicates them case-insensitively and shows a result row for each unique address.
