Supafax is an AI email assistant that works directly inside Gmail and Outlook. The company's tagline is "Email, done for you," and its homepage says it drafts replies, schedules meetings and prioritizes emails. It positions the product as a way to turn two hours of email into two minutes.
Rather than asking users to adopt a new inbox, Supafax operates in the mailbox they already use. The company is backed by Y Combinator, and the site footer credits Veriad, Inc. The product is sold on a per-user subscription with a free trial.
Setup has three steps. The user connects their inbox and calendar with one click, choosing Gmail or Outlook. Supafax then learns how the user works, including who they respond to, how they write and which emails are important. After that, it starts handling mail in the background.
Day-to-day control happens through email itself. A user can send Supafax a plain-English instruction, and it replies to confirm the rule and activates it right away. Rules and routines can be edited, paused or canceled by replying to the same thread, so no settings pages or code are involved.
Supafax drafts replies in the user's own voice, based on tone learned from past emails. Drafts are marked ready for review, with Edit and Send options. It also labels and prioritizes incoming mail by sender, email content or custom rules, using categories such as Clients, Billing, To do and Newsletters.
For scheduling, users CC Supafax on a thread and it finds times, confirms and sends calendar invites. Scheduled routines can send a morning brief, a Friday recap or a weekday digest of important threads. The Professional plan also lists an ask-your-inbox function, custom automation rules and priority support.
