Product Overview
What is Supafax?
Supafax is an email assistant that plugs directly into Gmail and Outlook without requiring a separate app or dashboard. It observes how a user writes and works, then drafts replies in their voice, auto-labels incoming messages, and manages back-and-forth scheduling by CC on a thread. Users can also set custom automation rules and recurring routines like morning digests simply by emailing instructions in plain English. The company launched publicly on Product Hunt in mid-2026 after raising a $1.5M seed round led by Y Combinator.
Key Features
Voice-Matched Reply Drafts
Learns a user's tone from past correspondence and generates ready-to-send replies that read naturally in their own writing style.
Smart Inbox Labeling
Automatically sorts and prioritizes incoming mail into labels like Clients, Billing, or To-do based on sender and content.
Autonomous Meeting Scheduling
Handles the entire back-and-forth of finding times, confirming slots, and sending calendar invites when CC'd on a thread.
Plain-English Automation Rules
Lets users describe custom rules for labeling, starring, or routing emails in everyday language, no triggers or settings menus required.
Scheduled Digests and Routines
Delivers recurring inbox summaries, such as a daily 9am recap of overnight threads, on a cadence the user defines.
Zero-Footprint Privacy Design
Operates read-only where possible and stores no email content, since it never sends or deletes anything without explicit instruction.
