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.
