Email Validator

Validate single or bulk email addresses instantly. Paste, type, or upload a CSV/TXT file. Get detailed valid/invalid breakdown with one-click export.

This email validator checks addresses against RFC 5322 syntax rules, catching problems like missing @ symbols, invalid domains, missing top-level domains, and overly long local or domain parts. Validate a single address as you type, paste a bulk list with one email per line (commas and semicolons work too), or upload a CSV or TXT file and preview its contents before checking. Results are broken down into valid, invalid, and duplicate counts with a pass rate percentage, and you can filter the list to see only valid or only invalid entries. Export clean lists for your email marketing platform or CRM, or copy just the valid addresses to your clipboard. It's useful for marketers cleaning signup lists, developers testing forms, and anyone who needs to catch typos before sending mail.
