Verify, clean, and send with confidence

A complete email verification toolkit for developers and marketing teams.

Real-Time Verification API

Validate any address in milliseconds. We check syntax, domain and DNS, MX records, and the mailbox SMTP response — all without sending an actual email.

Bulk List Verification

Upload a CSV, XLS, or XLSX file and verify an entire list at once. Track progress in the dashboard and export clean, ready-to-send results.

Disposable Email Detection

Flag temporary and throwaway domains like Mailinator and Guerrilla Mail so junk signups never reach your list.

Role & Catch-All Detection

Identify role-based addresses (info@, sales@, support@) and catch-all domains that accept any address, so you can send with full context.

Domain Authentication Checks

Verify MX, SPF, DKIM, and DMARC records for any domain to diagnose deliverability problems and spoofing risk before they cost you.

Deliverability Scoring

Every verification returns a confidence score from 0 to 1 and a clear verdict — Valid, Invalid, or Risky — so you can decide with certainty.

Contact & List Management

Organize, tag, and segment contacts and lists right in the dashboard, and keep your data clean over time.

Email Sending & Domain Verification

Send from your own authorized, verified domains with built-in domain authentication for better inbox placement.

Developer API & Webhooks

A RESTful API with Bearer-token authentication, rate-limit headers, webhooks, and copy-paste examples in JavaScript, Python, PHP, and cURL.

Built for developers

Verify a single address with one request. Authenticate with a Bearer token, get back a structured JSON verdict and score, and integrate in minutes.
