Key Takeaway
Gmail's built-in spam filter misses up to 45% of AI-generated cold outreach emails because they use legitimate domains, proper formatting, and AI-written content that avoids spam trigger words. Email Ferret enhances Gmail by analyzing 15+ behavioral signals—including domain trust, sales intent, and automation tool fingerprints—to catch what Gmail misses. Setup takes under 2 minutes, costs $5/month, and never stores your email content.

Why Does Gmail's Spam Filter Miss AI Cold Outreach?

Real Domains

Cold outreach uses legitimate domains and proper email formatting. According to industry research, 45% of cold outreach now uses AI-warmed domains with clean sender reputations, so Gmail's reputation checks pass.

AI-Generated Content

Nearly half of all cold outreach is now AI-generated using tools like ChatGPT, avoiding spam trigger words while sounding human. Gmail's keyword-based filters miss these sophisticated messages.

Behavioral Patterns

Gmail doesn't analyze behavioral patterns like automation tool fingerprints, sales intent, or thread engagement that reveal cold outreach.
