Kaiju vs Competitors: A Technical Deep Dive

The email verification market is crowded. You have giants like ZeroBounce and Hunter.io charging premium rates. Then you have Kaiju. How do we compare?

1. The Pricing Disruption

Most competitors charge between $0.002 and $0.008 per email. Kaiju charges a flat $0.001 per email. That's 50-80% cheaper.

How? We don't have a massive sales team or expensive headquarters. We are a lean, engineering-first team focused on one thing: efficiency.

2. The Technology Stack

Many older verifiers rely on cached data that can be weeks old. Kaiju uses a real-time, distributed worker architecture.

• Concurrent Processing: We verify multiple emails in parallel using non-blocking I/O.
• Smart Caching: We cache MX records (DNS) but perform fresh SMTP handshakes for every mailbox.
• Disposable Detection: We maintain a constantly updated list of disposable domains.

3. Privacy First

Competitors often store your data for "analytics" or to enrich their own databases. Kaiju has a strict Zero Retention Policy. Your data is processed in RAM and wiped instantly.
