Email Ferret vs Gmail Spam Filter

Gmail checks for authentication (SPF, DKIM, DMARC), sender reputation, and known spam patterns. AI-generated cold outreach passes all these checks because it comes from authenticated domains, is sent one-to-one (not bulk), and uses AI to avoid spam trigger words. To Gmail, a cold sales email looks identical to a legitimate business email.

No. Email Ferret works alongside Gmail spam filter, not instead of it. Gmail continues to handle phishing, bulk spam, and known malicious senders. Email Ferret adds a layer on top that catches the AI-generated cold outreach and BDR/SDR emails that Gmail misses, then organizes your remaining email into smart folders.

Email Ferret uses 15+ heuristic signals including LLM-powered sales intent detection, domain trust assessment, BDR phrase fingerprinting, automation tool header detection (Outreach, Salesloft, HubSpot), and thread engagement analysis. These signals specifically target the patterns of AI-generated cold outreach.

Yes. Email Ferret is Google API compliant, never stores your email content (analyzed in real-time and discarded), uses AES-256-GCM encryption, and has row-level security isolation. It only adds Gmail labels and folders — it never modifies or deletes your emails.

Yes. Email Ferret offers a 14-day free trial with no credit card required. All features are included during the trial. After that, it costs $5/month per mailbox.

Gmail Priority Inbox uses basic engagement signals (how often you read/reply) to sort email into Important and Everything Else. Email Ferret uses advanced heuristic analysis to detect AI-generated cold outreach specifically, then organizes legitimate email into 10+ smart folders (Important, Calendar, Billing, Recruiting, etc.). Email Ferret catches emails Priority Inbox considers "important" because they look like real business correspondence.
