Free Email Verifier Tool
Verify email addresses in real-time to reduce bounce rates and protect your sender reputation. Check if an email is valid, active, and can receive messages before adding it to your campaign.
Why Email Verification Matters for Deliverability
Invalid email addresses cause bounces, which damage your sender reputation and hurt deliverability. Our email verifier checks addresses in real-time to ensure you're only sending to valid inboxes. This is critical for maintaining high deliverability rates and protecting your domain reputation.
- Reduce bounce rates by verifying emails before sending campaigns
- Protect sender reputation and domain health from invalid addresses
- Save time and resources by catching invalid addresses early
- Improve deliverability rates across all email campaigns
- Maintain clean email lists and reduce spam complaints
How Email Verification Works
Our email verification tool uses multiple validation methods to ensure accuracy:
- Syntax validation: Checks if the email address follows the correct format (e.g., user@domain.com)
- Domain verification: Validates that the domain exists and has valid MX (Mail Exchange) records
- SMTP connection: Attempts to connect to the mail server to verify the mailbox exists
- Disposable email detection: Identifies temporary or disposable email addresses
- Role-based detection: Flags generic addresses like info@, support@, or admin@ that may have lower engagement
This comprehensive approach ensures you're only sending to valid, active email addresses that can receive your messages.
