Email Validator: Verify Email Addresses
Our email validator checks if email addresses are valid and deliverable. Validate syntax, verify MX records, detect disposable emails, identify role-based addresses, and check for common typos. Perfect for cleaning email lists and improving deliverability.
Email validation is essential for marketers, sales teams, and anyone who collects email addresses. Invalid emails cause bounces, hurt sender reputation, and waste resources. Our validator helps you maintain a clean, high-quality email list.
What We Check
Syntax Validation: Checks if the email follows the correct format (user@domain.tld).
MX Record Check: Verifies the domain has mail servers configured to receive email.
SMTP Verification: Confirms the mailbox actually exists on the server (premium).
Disposable Detection: Identifies temporary email services like Mailinator, Guerrilla Mail.
Role-Based Detection: Flags generic addresses like info@, support@, admin@.
Free Provider: Indicates if email is from Gmail, Yahoo, Outlook, etc.
Why Email Validation Matters
Reduce Bounces: High bounce rates damage your sender reputation.
Improve Deliverability: Clean lists have better inbox placement rates.
Save Money: Don't pay to send to invalid addresses.
Prevent Fraud: Disposable emails are often used for abuse.
Better Analytics: Accurate lists mean accurate metrics.
Email Types Explained
Free Provider: Gmail, Yahoo, etc. Common for B2C but may indicate lower intent for B2B.
Disposable: Temporary emails that expire. Often used for sign-ups without intent to engage.
Role-Based: Generic departmental emails (info@, support@). Typically managed by teams, not individuals.
Catch-All: Domains configured to accept any email. Makes verification harder.
FAQ
How accurate is email validation?
Syntax and MX checks are nearly 100% accurate. SMTP verification is highly accurate but can't catch catch-all domains. No validator can guarantee 100% delivery, but validation significantly reduces bounces.
Should I remove all role-based emails?
Not necessarily. Role-based emails are legitimate for business contact but may have lower engagement. Consider your use case—they're fine for transactional emails but risky for marketing campaigns.
