Supafax Review (2026): Pricing, Features & Honest Verdict

Supafax Review: The TLDR

Supafax is an AI email assistant that lives inside Gmail and Outlook, drafting replies in your voice, sorting your inbox with labels, and scheduling meetings for you. It is a polished, YC-backed take on inbox automation. Best for busy founders and operators drowning in email. Price: from $35/mo per user (free plan: no, but a 14-day trial). Rating: 7/10.

What Is Supafax?

Supafax is an AI agent that handles your email and calendar so you spend less time in your inbox. It plugs into Gmail and Outlook, reads your incoming mail, drafts responses that sound like you, and keeps everything organised with labels. It can also book meetings, answer questions about your inbox, and run automation rules you set once.

We found Supafax through its Product Hunt launch, and it comes from Veriad, Inc., a Y Combinator company in the W26 batch. The founders, Rohan and Anton, previously built compliance software and sold enterprise deals, so they know the pain of an inbox that never empties. Supafax is their attempt to put a real assistant in front of it. This is a young product, launched in mid-2026, but it already feels considered rather than slapped together.

What Are Supafax’s Key Features?

Reply Drafting In Your Voice

The headline feature is drafting. Supafax reads an incoming email and writes a reply that matches how you actually write. It learns your tone from your sent mail, so the drafts are not generic AI mush. You review, tweak if needed, and send. For anyone who answers the same kinds of emails ten times a day, this is the part that saves real minutes.

Automatic Inbox Organisation

Supafax applies labels to incoming mail so your inbox stops being a single undifferentiated pile. It separates what needs a reply from what can wait, and it does this without you building a wall of manual filters. The promise here is a calmer inbox you can scan in seconds instead of dread.

Meeting Scheduling

When an email turns into “let’s find a time,” Supafax handles the back and forth. It checks your calendar, proposes slots, and books the meeting. This is the kind of grunt work that eats an afternoon in small chunks, and handing it to software is an easy win.

Inbox Queries And Custom Rules

You can ask Supafax questions about your inbox, like what you still owe a reply on, and it answers. On top of that, you can set custom automation rules so the same repeated decision happens automatically. Set it once, and Supafax applies it every time that pattern shows up.

How Much Does Supafax Cost?

Supafax starts at $35 per month per user on the Professional plan, which was recently reduced from $50. That single paid tier includes the reply drafting, inbox organisation, meeting scheduling, inbox queries, custom automation rules, and priority support. There is a 14-day free trial with no credit card required, but there is no permanent free plan.

An Enterprise tier exists with custom pricing for teams that need a dedicated account manager, custom integrations, and SSO or SCIM controls. Compared to rivals, $35 sits in the middle. Fyxer runs about $30 per month, Superhuman is roughly $25 to $33 per month, and Shortwave has a free tier with paid plans climbing toward $40. Supafax is not the cheapest, and the lack of a free plan stings when competitors offer one.

Who Is Supafax Best For?

Use Supafax if you are a founder, executive, or operator who lives in Gmail or Outlook and loses an hour or more a day to email. The drafting and scheduling features pay for themselves fastest when your inbox is high volume and repetitive.

Skip Supafax if you only get a handful of emails a day, if you are precious about an AI touching your mail, or if you want to try a tool indefinitely before paying. With no free plan and a brand-new company behind it, cautious buyers may want to wait a few months and watch how it matures.

What Are The Best Supafax Alternatives?

Fyxer is the closest competitor. It also drafts replies and organises your inbox across Gmail and Outlook, and at around $30 per month it is slightly cheaper. It is more established, which matters if you want a track record.

Superhuman is a faster, keyboard-driven email client with AI features baked in. At roughly $25 to $33 per month it is priced similarly, but it is a full client replacement rather than an assistant that sits on top of your existing inbox.

Shortwave rebuilds Gmail with an AI assistant and offers a genuine free tier, with paid plans reaching toward $40 per month. If a free plan is a dealbreaker, start here.

Final Verdict: Is Supafax Worth It?

Supafax does the boring parts of email well. The drafting actually sounds like you, the labels bring order, and the scheduling removes a chore most people hate. For a high-volume inbox, $35 a month is easy math against the time it gives back. The YC backing and a founding team that has shipped before are reasons to take it seriously rather than dismiss it as another AI wrapper.

The caution is age. This is a W26 company with one paid tier and no free plan, so you are buying into something early. If you want a calmer inbox today and your email volume justifies the cost, Supafax is worth the trial. If you would rather see it survive a year first, set a reminder and check back. We rate it 7 out of 10, with most of the missing points down to it being new and the absence of a free plan.
