Smart Email Filter Add-on for Gmail

A Gmail Workspace add-on designed to streamline your inbox by automatically filtering and organizing incoming emails based on sender recognition, domain history, and user-defined safe lists. Ideal for users who want a cleaner, distraction-free Gmail experience.

Core Features

• Automatic Labeling & Archiving: Messages from unfamiliar senders are labeled and archived without cluttering your inbox.
• Public & Private Domain Filtering: Filters emails from public domains (e.g., gmail.com, yahoo.com.*) and unknown private domains.
• Safe Sender Management: Automatically whitelists users you’ve previously emailed. Allows manual management via the Gmail add-on panel.
• Spam-Aware: Does not interfere with Gmail’s native spam detection—already-spam-labeled emails are excluded from processing.
• Freemium Support: Free users are allowed up to 250 filtered emails/month, with upgrade prompts once the limit is reached.

User Interface
