MX Record Check

Risk Assessment

Detects role-based addresses (info@, admin@) and free providers (Gmail, Yahoo).

How Email Verification Works

Email verification is the process of confirming that an email address is valid, deliverable, and safe to send to — without actually sending a message. Our free tool performs real-time checks across multiple validation layers.

When you enter an email address, we first validate the syntax against RFC 5321 standards. Then we perform a DNS lookup to verify the domain exists and has properly configured MX (Mail Exchange) records. We also check our database of 60+ known disposable email providers and identify role-based addresses that are less likely to be individual recipients.

Why Email Verification Matters

Sending emails to invalid addresses damages your sender reputation. High bounce rates (above 3%) trigger spam filters at major email providers like Gmail, Outlook, and Yahoo — causing even your valid emails to land in spam folders.

Email lists naturally decay at approximately 2% per month as people change jobs, companies close, and providers recycle addresses. Regular verification is essential for maintaining deliverability.

Free vs. Paid Email Verification

This free tool is perfect for checking individual emails before sending. For bulk verification, API integration, and advanced features like SMTP verification, webhook support, and SLA guarantees, upgrade to FatihAI Email Verify starting at $29/month with flat monthly pricing.

Email Verification Best Practices

  • Always verify emails before adding them to your outreach campaigns
  • Re-verify your email lists monthly to account for natural decay
  • Remove hard bounces immediately — never retry invalid addresses
  • Set up SPF, DKIM, and DMARC authentication on your sending domain
  • Keep bounce rates below 1% for optimal deliverability
