Email
Validation
Multi-signal email verification — MX record checks, syntax validation, disposable email detection, and catch-all identification. Know if an address will deliver before it enters your system.
MX Record Verification
Checks mail exchanger records exist and are configured to accept mail. Catches domain-level issues before sending.
Syntax Validation
RFC 5322 compliant syntax checking. Catches common typos — missing @ symbols, invalid characters, malformed domains.
Disposable Email Detection
Identifies temporary and throwaway email services. Block fake signups and protect sender reputation.
Catch-All Detection
Identifies domains accepting all mail regardless of mailbox existence — a common source of bounce-hidden failures.
Deliverability Score
A single confidence score combining all signals into an actionable deliverability indicator for each address.
Real-Time & Bulk
Validate at point of capture via API or cleanse existing lists in batch. Both modes available on all plans.
