What this validator checks
- Format — RFC 5322 simplified regex (covers 99% of real-world emails)
- Domain MX records — queries Cloudflare DNS-over-HTTPS to confirm the domain accepts email
- Common typos — detects misspellings like gmial.com, hotnail.com, yaho.com
- Disposable services — flags throwaway email domains (mailinator, tempmail, 10minutemail, etc.)
- Role accounts — flags generic addresses like admin@, info@, noreply@ that often don't reach individuals
Notes
- MX existence does not guarantee the specific inbox exists — that would require SMTP RCPT TO probing, which most servers no longer allow
- All checks happen in your browser; the email address is not stored or sent anywhere except DNS
