Superhuman and Polymail both sell a polished email client, but they serve opposite halves of the workday. Superhuman is built for triage: getting through an inbox fast. Polymail is built for outbound: tracking opens, chasing replies, and running sequences. Pick wrong and you either pay $300/year for speed when what you actually need is read receipts, or shell out for sales features you’ll never use. After three weeks, here’s how they split.
The One-Sentence Verdict
Go with Superhuman if your problem is inbox overload and you want AI plus keyboard speed. Go with Polymail if you’re in outbound sales and need read receipts, follow-up reminders, and automated sequences on a schedule.

What Each One Actually Is
Superhuman
Superhuman is a VC-backed email client out of San Francisco that rebuilt the Gmail and Outlook experience from scratch. It bills itself as the fastest email experience in the world, and after three weeks of daily use I kept landing on the same word: instant. The Mac and iOS apps are mature; Windows and Android are newer but catching up. It’s not a team help desk and not a calm-inbox reset tool—it’s a precision instrument for people who plow through hundreds of emails a day.
- Split Inbox auto-separates team, VIP, and tool mail
- Built-in AI: Auto Summarize, Instant Reply, Auto Drafts, Auto Archive
- Command palette and keyboard-first flow (n, e, r, s)
- Integration sidebar: Slack, Notion, Linear, Figma, GitHub, Calendly
- Read receipts, scheduling, recurring reminders, snooze
| Plan | Price |
|---|---|
| Starter | $25/mo annual ($300/yr) or $30 monthly |
| Business | $33/mo annual ($396/yr) or $40 monthly |
| Enterprise | Custom pricing (SSO, security, dedicated success) |
Polymail
Polymail is a polished email client aimed at salespeople and founders who live in outbound. Its core weapons are Email Tracking (see who opened your email and when), Follow-up Reminders, and Automated Sequences on Premium. The design is clean and onboarding is quick, but recurring complaints on G2 and Capterra center on sync gaps and thin support.
- Email Tracking and read receipts in real time
- Follow-up Reminders on every thread
- Automated Sequences chase non-responders (Premium)
- Calendar Scheduling drops a booking link
- Send Later, templates, and unified inbox
| Plan | Price |
|---|---|
| Basic | $10/user/mo annual ($13 monthly) — 2 mailboxes, tracking, reminders, Send Later, templates, 1 Calendar Page |
| Premium | $24/user/mo annual ($29 monthly) — 20 mailboxes, Automated Sequences, Calendar Scheduling |
| Enterprise | Custom — Salesforce integration, SSO, advanced analytics, phone support |
Where Superhuman Wins
I ran both on the same inbox for three weeks. Superhuman cleared 120 emails in 11 minutes using keyboard shortcuts and Split Inbox. Polymail’s interface is clean, but without a shortcut model I was reaching for the mouse on every message. The bigger gap was AI: Superhuman summarized a 40-message thread in one tap and drafted a reply I could lightly edit. Polymail has no AI at all—you’re on your own for every draft.
On G2, Superhuman’s recurring praise is speed and the concierge onboarding. The recurring complaint is price: one Capterra user called it ‘a bit expensive considering it is basically a front-end for Gmail.’ If you’re not a power user, that critique lands.
Where Polymail Wins
Polymail won on outbound. I sent 30 cold emails from the test account and watched the tracking dashboard show who opened, when, and how many times. One prospect opened the email six times over two days and never replied—Polymail’s Follow-up Reminder nudged me to send a follow-up, which got a reply. On Premium, Automated Sequences would have handled that chase on a schedule. Superhuman has read receipts, but no tracking dashboard and no sequence engine.
The recurring complaints on G2 are sync and support. One user reported ‘Not all emails are synced,’ and another described support plainly as ‘Poor Customer Support.’ Search is weak—one user said you have to ‘type in the WHOLE name’ to find a contact. The product works; it just doesn’t work reliably at scale.
The Price Math
Solo user (1 person, 1 year)
Superhuman: Superhuman Starter annual: $300/yr. AI, shortcuts, integrations, read receipts — $300/yr.
Polymail: Polymail Basic annual: $120/yr. Tracking, reminders, Send Later, templates. Sequences require Premium at $288/yr — $120/yr (Basic) / $288/yr (Premium).
Verdict: Polymail Basic is $180/year cheaper than Superhuman. If you only need tracking and reminders, that is a clear win. If you need sequences, Polymail Premium ($288) is almost the same price as Superhuman but with no AI.
Team of 5 (1 year)
Superhuman: Superhuman Business for 5: $33/mo × 5 × 12 = $1,980/yr — $1,980/yr (Business x5).
Polymail: Polymail Premium for 5: $24/user/mo × 5 × 12 = $1,440/yr. Includes sequences and Calendar Scheduling — $1,440/yr (Premium x5).
Verdict: Polymail Premium is $540/year cheaper than Superhuman Business for a five-person outbound team. But Polymail has no AI, no shared inbox, and weak support—so the savings come with real trade-offs.
