Powerful Features

Email Ferret uses AI to automatically categorize legitimate emails (those that pass the spam check) into custom folders like Important, Calendar, Collaboration, Updates, Recruiting, Billing, and more. You can enable or disable folders based on your needs. Messages are automatically archived after categorization (except the Important folder, which stays in your inbox).

You can add senders or domains to your allowlist from the Rules page or directly from any message. Allowlisted senders receive a strong trust signal that reduces their spam score. Blocklisted senders are always flagged regardless of other factors. Both lists are specific to each Gmail account you connect.

Email Ferret uses heuristic analysis to score emails based on multiple factors: domain validation, sender behavior, content patterns, and authentication results. Primary indicators (domain issues, missing avatar) are weighted heavily. Secondary indicators (reply-to mismatch, BDR phrases, sales intent) have reduced weight. Trust signals (allowlist, previous contact, same domain) reduce the score. The default threshold is 3, but you can customize it per Gmail account.

Yes! You can enable or disable any of the standard folders (Important, Calendar, Collaboration, Updates, Recruiting, Billing, Finance, Socials, Notetakers, News, Shopping) from the Settings page. When you enable or disable folders, Email Ferret automatically manages the Gmail labels with sequential numbering to keep them organized.

When an email is flagged (score above your threshold), Email Ferret automatically applies a label in Gmail. You can configure whether flagged emails are archived or kept in your inbox. You can review flagged emails in the Messages page, see the detailed score breakdown, and add senders to your allowlist or blocklist if needed.

Email Ferret analyzes email content in real-time and immediately discards it. We only store encrypted email subject lines and IDs to enable the user interface. Your email content is never stored, sold, or shared. All stored data is encrypted using AES-256-GCM and isolated per user with Row-Level Security. We comply with Google API Services User Data Policy.

Yes! Email Ferret supports multiple Gmail accounts. Each account has its own settings, allowlist, blocklist, folder configuration, and message history. Each Gmail account is billed separately at $5 per mailbox per month. You can switch between accounts easily from the dashboard.

Email Ferret uses advanced heuristic analysis to identify behavioral patterns that indicate AI-generated cold outreach. The system is designed to catch sophisticated sales pitches that traditional spam filters miss. You can improve accuracy by maintaining an allowlist of trusted senders and adjusting your spam threshold. The system learns from your preferences over time.
