Built for Deliverability

Anti-Ban Engine

Full SOCKS4/5 & HTTP proxy support with user:pass auth. Auto-drops dead proxies to keep hits high. Randomizes HELO & Sender Identity per check.

True Catch-All Detection

We don't guess. V3 actively probes servers with randomized ghost accounts to mathematically prove Catch-All domains. Identifies hidden enterprise setups (O365, Workspace).

Smart Rate Limiting

Never trigger temporary blocks from strict providers again. Set global speed limits AND precise per-domain speed limits using our intelligent Token Bucket algorithm.

Combo Deduplication

Automatically strips Gmail dot-tricks and plus-aliases so you don't waste bandwidth verifying the same inbox 50 times. Auto-extracts emails from messy combo lists.

Greylisting & 4xx Bypass

Intelligently handles temporary 4xx blocks and greylisting. By analyzing real-time SPF and DMARC DNS records, V3 requeues and verifies strict domains instead of dropping them.

Multi-Format Auto-Export

Never sort your results manually again. V3 automatically categorizes your checks into Live, Dead, Risky, and Catch-All, exporting to clean TXT, CSV, or structured JSON folders instantly.

High-Concurrency Engine

Built natively in Go to leverage thousands of lightweight threads. Maximize your VPS hardware to scan multi-million line databases simultaneously without memory leaks.

Instant Syntax Validation

Before even making a network request, V3 drops malformed emails, typo domains, and invalid syntax. Stop wasting valuable proxy bandwidth on structurally broken targets.

Real-Time Domain Count

Track your scanning progress with precise live metrics. The dashboard categorizes emails by provider (Gmail, Workspace, Yahoo, etc.) to give you real-time insights into your list's domain composition.
