# Email Ferret

> Email Ferret is a Gmail AI/BDR spam filter. It detects AI-generated cold outreach and sales emails using heuristic scoring plus LLM checks, then labels them in Gmail so your inbox stays clear. Privacy-first, works across multiple accounts, and costs $5/month after a 14-day free trial (no credit card required).

## Key facts

- What it does: automatically detects and labels AI-generated cold outreach, BDR/sales sequences, and spam in Gmail.
- How it works: heuristic scoring (sales intent, automation fingerprints, BDR phrasing, new-sender signals) combined with LLM checks. It targets cold outreach behavior, not the sending platform, so it catches rotating domains and AI-personalized email.
- Allowlist/blocklist: trusted contacts always pass through; specific senders can be blocked.
- Pricing: $5/month after a 14-day free trial. No credit card required to start.
- Privacy: privacy-first; designed to analyze email for filtering without selling data.
- Platform: Gmail (web app + Chrome extension).
- Scale: scans over 1 million emails per month and flags tens of thousands of unwanted emails.
