📖 About Email Validation
Email validation is crucial for maintaining clean mailing lists, preventing fraud, and ensuring your messages reach real recipients. Our validator performs multiple checks to give you comprehensive results.
What We Check
- Format Validation - RFC 5322 compliant email format check
- Domain Existence - Verifies the domain has valid DNS records
- MX Records - Checks if the domain can receive emails
- Disposable Detection - Identifies temporary email services
- Typo Detection - Catches common domain typos
💡 Pro Tip: Use "Full Analysis" mode for the most comprehensive validation. It performs all checks including DNS verification and disposable email detection.
❓ Frequently Asked Questions
Our validator checks email format (syntax), domain existence through DNS lookup, MX records to verify the domain can receive emails, and screens against known disposable email providers.
We can verify that a domain exists and can receive emails, but we cannot 100% confirm if a specific mailbox exists without sending a test email. Our "existence check" gives you a probability based on available data.
MX (Mail Exchange) records are DNS records that specify which mail servers are responsible for receiving email for a domain. If a domain has no MX records, it cannot receive emails.
Disposable emails are temporary email addresses from services like Mailinator or 10MinuteMail. They're often used to avoid spam but can also indicate low-quality leads or potential fraud.
Yes! All validation happens in your browser. We don't store, log, or transmit your email addresses to any server. DNS lookups are made through public DNS services (Google DNS).
