What is Supafax
Supafax is an AI agent for email and calendar that “lives” directly in your inbox, helping individuals and teams handle email faster with less manual sorting and back-and-forth. It focuses on core productivity tasks—writing responses, organizing messages, and coordinating meetings—without requiring a new app or complex setup. Users connect their Gmail or Outlook once, then use Supafax to manage day-to-day inbox work through simple requests, including custom rules and recurring digests or recaps.
Key Features of Supafax
Supafax is an AI agent that works inside Gmail and Outlook to reduce time spent on email by drafting replies in your personal tone, scheduling meetings end-to-end, prioritizing and organizing the inbox, and automating recurring workflows. You can create rules and routines in plain English (no settings pages or code), ask your inbox questions to find next steps or documents and summarize unread threads/newsletters, and manage or adjust automations simply by replying—aimed at turning hours of daily email into minutes with minimal setup.
Reply drafting in your voice: Learns your tone from past emails and generates draft responses that sound like you, ready for review and sending.
Automated meeting scheduling: Handles the back-and-forth by being CC’d on threads—finds times, confirms details, and sends calendar invites.
Inbox prioritization and organization: Prioritizes emails based on sender, content, or custom rules and can organize messages with labels to keep the inbox manageable.
Plain-English automation rules: Create new inbox rules by describing what you want in natural language; Supafax confirms the rule and activates it immediately, running continuously until edited or removed.
Ask-your-inbox Q&A and summarization: Email yourself questions like “what are the next steps?” or “where is that doc?” and get answers; can also summarize unread newsletters or threads.
Scheduled routines (digests, recaps, reminders): Creates recurring email routines such as morning briefs or weekly recaps, delivered on a cadence you specify; pause/change/cancel by emailing yourself.
Use Cases of Supafax
Sales and customer success follow-ups: Drafts consistent replies to prospects/customers, prioritizes urgent accounts, and automates follow-up rules to prevent leads or renewals from slipping.
Recruiting and HR coordination: Schedules interviews by handling availability checks and calendar invites, and drafts candidate communications while keeping threads organized.
Executive assistant workflow for leaders: Triages and prioritizes inbound email, drafts responses in the exec’s tone, and runs daily/weekly digests to reduce inbox overload.
Professional services (legal, consulting, agencies): Summarizes long client threads, surfaces next steps and requested documents, and automates routing/labeling of client communications.
Operations and internal IT request handling: Uses rules to categorize and prioritize internal requests, send standard responses, and produce periodic recaps of open items.
Pros
Works directly inside Gmail and Outlook (no separate app), with minimal setup.
Natural-language rules and routines make automation accessible without technical configuration.
Time-saving bundle: drafting, scheduling, prioritization, and inbox Q&A/summaries in one tool.
14-day free trial with no credit card required (lower friction to evaluate).
Cons
Requires access to email content and history to learn tone and operate, which may be a concern for privacy-sensitive users/orgs.
Best results may depend on having sufficient past emails for tone learning and clear patterns for automation.
Automation behavior may need occasional oversight/adjustments to avoid mis-prioritization or incorrect handling of edge cases.
