free email verifier
that actually works
Verify any email address instantly. Our free email verifier goes beyond simple pattern matching with real SMTP verification to confirm if a mailbox actually exists.
What our free email verifier checks
Every email you verify goes through multiple validation layers. Try verifying emails in the playground above, no signup needed.
Syntax Validation
Checks email format against RFC 5322 standards. Catches typos, missing domains, and invalid characters.
MX Record Lookup
Verifies the domain has valid mail servers configured. Filters out non-existent and parked domains.
Disposable Email Detection
Identifies throwaway email addresses from 100,000+ known disposable email providers, updated daily.
SMTP Mailbox Verification
Connects to the recipient's mail server to verify the mailbox actually exists. 97%+ accuracy.
Catch-All Detection
Detects wildcard domains that accept emails to any address, helping you identify risky contacts.
Deliverability Scoring
Every email gets a 0.0-1.0 confidence score and a quality grade: excellent, good, fair, or poor.
