How it works

Clean your list in three simple steps.

01

Upload, paste, or call the API

Drop a CSV, paste addresses, or send a single API request. Bulk and real-time use the same backend.

02

We verify

Our engine checks syntax, domain, mailbox existence, and flags disposable, role-based, and catch-all addresses.

03

Download, integrate, or act

Export your clean list, push results back via API, or block invalid addresses at signup. Bounce rate drops, sender reputation stays intact.

Or skip the UI entirely and call our API. Same engine, same results, programmatically.

Features

Every check you need, in one API call.

Bounce detection

Identify hard bounces before your ESP does, so they never count against you.

Disposable email detection

Catch throwaway addresses from 30,000+ temporary email providers.

Catch-all verification

Go deeper than basic SMTP checks to determine whether catch-all mailboxes actually accept mail.

API access

Verify addresses programmatically with a clean REST API. Single calls or bulk jobs, same endpoint.

Role & free email flags

Know which addresses are info@, sales@, or from free providers like Gmail.

Deduplication & syntax cleanup

Automatic removal of duplicates, typos, and malformed addresses.

Use cases

Built for every team that sends email.

Marketing teams

Cleaning lists before campaigns to protect deliverability and improve open rates.

→ List hygiene

Development teams

Validating signups in real time at the form, so the database stays clean from day one.

→ Real-time API

Sales teams

Verifying leads from cold outreach and prospecting tools before pressing send.

→ Bulk verification

For developers

Built API-first. Drop it into anything.

A clean REST API with predictable JSON responses. No SDK lock-in, no proprietary formats — just one endpoint that works with whatever stack you're already using.
