Product Overview
What is Supafax?
Supafax is an email assistant that plugs directly into Gmail and Outlook without requiring a separate app or dashboard [page:1]. 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 [page:1]. Users can also set custom automation rules and recurring routines like morning digests simply by emailing instructions in plain English [page:1]. The company launched publicly on Product Hunt in mid-2026 after raising a $1.5M seed round led by Y Combinator [web:11][web:10].
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 [page:1].
Smart Inbox Labeling
Automatically sorts and prioritizes incoming mail into labels like Clients, Billing, or To-do based on sender and content [page:1].
Autonomous Meeting Scheduling
Handles the entire back-and-forth of finding times, confirming slots, and sending calendar invites when CC'd on a thread [page:1].
Plain-English Automation Rules
Lets users describe custom rules for labeling, starring, or routing emails in everyday language, no triggers or settings menus required [page:1].
Scheduled Digests and Routines
Delivers recurring inbox summaries, such as a daily 9am recap of overnight threads, on a cadence the user defines [page:1].
Zero-Footprint Privacy Design
Operates read-only where possible and stores no email content, since it never sends or deletes anything without explicit instruction [web:7].
