Features

Everything you need to clean a list

Ten verification layers, bulk processing, a developer API, native GoHighLevel, and a Chrome Extension — one platform, agency pricing.

The engine

10 layers on every email

Each address runs the full pipeline — the same depth as the premium tools.

Syntax (RFC 5322)

Strict format validation and length limits before anything else runs.

Typo detection

Catches gmial.com-style mistakes with one-click suggested fixes.

Disposable domains

Checked against a 74,000+ disposable/temporary-mail domain list.

Free & role detection

Flags free providers and role addresses (info@, sales@) that hurt deliverability.

MX records

Live DNS lookup confirms the domain can actually receive mail.

SMTP mailbox probe

Real-time handshake to the mail server to check whether the mailbox exists.

Catch-all detection

Identifies accept-all domains so you know when a "valid" is uncertain.

Blacklist (Spamhaus/SURBL)

Domain-level blocklist checks against industry sources.

Gateway awareness

Detects Proofpoint, Mimecast, Microsoft 365 & Google and labels results honestly.
