What is Supafax?

Supafax is an email-native assistant that works inside Gmail and Outlook to handle your inbox end-to-end. It learns how you communicate, drafts replies in your voice, prioritizes messages, schedules meetings, and even answers questions about past emails—all without leaving your inbox. Think of it as a personal executive assistant that runs on email itself.

Who it's for

• Busy professionals who spend hours each day managing email and need a faster way to triage, reply, and stay on top of commitments.
• Founders and executives who juggle high-volume inboxes with client, investor, and internal threads and want to cut email time from hours to minutes.
• Remote and async teams who rely on email as their primary communication channel and need reliable automation for labeling, reminders, and daily digests.

Key features

Replies drafted in your voice

Supafax learns your tone from past emails and writes replies that sound like you. It can draft a response to a client meeting request, attach relevant files, and even send a calendar invite—all in one go. You just review and hit send.

Your inbox auto-labeled

Supafax prioritizes your inbox based on sender, email content, or any custom rule you define. It automatically labels messages as "Clients," "Billing," "To do," or "Newsletters," so the important stuff rises to the top without manual sorting.

Ask your inbox anything

You can email yourself a question—like "When did Sarah send the Acme contract?"—and Supafax replies with the answer, pulling key terms, dates, and related threads from your inbox. It's like having a search engine trained on your own email history.

Automate your inbox with rules

Describe a rule in plain English—for example, "label anything from Y Combinator as Investors and star it"—and Supafax confirms, saves, and activates it instantly. No settings pages, no code, just a natural language instruction that runs forever.
