Features
Everything you need to keep your list clean
From single-email checks to million-row bulk imports, VerifyKit covers every validation scenario your team will encounter.
Real-time Validation
Validate emails on-the-fly as users type. Catch typos, disposable addresses, and invalid domains before they enter your system.
Bulk Verification
Upload CSV files and validate millions of emails in parallel. Clean your entire list in minutes, not hours.
Spam Trap Detection
Identify known spam traps and honeypots that damage your sender reputation and deliverability scores.
Global MX Lookup
Deep DNS checks across 150+ countries. Verify MX records, SMTP handshakes, and mailbox existence globally.
Analytics Dashboard
Track validation trends, bounce predictions, and list health scores with real-time reporting and alerts.
Risk Scoring
Each email receives a confidence score from 0-100. Set thresholds to auto-accept, review, or reject addresses.
How it works
Three steps to cleaner data
Send a request
Pass any email address to our REST API or use one of our SDKs. A single HTTP call is all it takes.
We run 20+ checks
Syntax, MX records, SMTP handshake, disposable detection, spam trap matching, and risk scoring all happen in parallel.
Get a clear verdict
Receive a structured JSON response with a deliverability verdict, confidence score, and detailed check results.
