Polymail vs Superhuman Mail

Polymail

• Founders and salespeople who run their deals from the inbox
• Replacing separate tracking, scheduling and outreach add-ons with one app
• Managing several Gmail, Outlook or iCloud accounts in one inbox

Superhuman Mail

• People on Gmail or Outlook who work through a high volume of email
• Teams that want to share and comment on threads instead of forwarding them
• Sales teams on HubSpot, Salesforce or Pipedrive (Business plan and up)

Polymail

• There is no free plan: after the 7-day trial a paid plan is needed to keep using the app.
• Basic connects only 2 email accounts; sequences and up to 20 accounts need Premium at $24 per user / month, billed yearly.
• The download page offers Mac, Windows and iOS apps only, alongside the web app; no Android or Linux app is listed.
• Salesforce integration, SAML single sign-on and advanced analytics are limited to the custom-priced Enterprise plan.

Superhuman Mail

• There is no free plan, and the pricing page does not mention a free trial.
• Built for Gmail and Outlook accounts; the vendor lists no other email providers.
• Auto Drafts, Ask AI and the HubSpot, Salesforce and Pipedrive integrations are not included in Starter.
• Starter and Business stop at 25 seats; single sign-on and SCIM are Enterprise only.

Polymail

Email tracking

Per-recipient open tracking plus link and attachment tracking, with every open, click and download timestamped in a searchable activity feed.

Follow-up reminders and Read Later

A reminder returns a thread to the inbox if nobody replies within a set time, and Read Later moves non-urgent mail away until the date and time you choose.

Send later and templates

Schedule an email for later delivery, even while offline, and reuse message templates with placeholders. Premium lets a team share templates.

Sequences

Automated, personalized follow-up emails for outbound outreach, run from the inbox rather than a separate sales tool. Sequences are part of the Premium plan.

Calendar scheduling

Share your availability so contacts can book a time without back-and-forth, and send calendar invites from the app. Basic includes 1 calendar page and Premium 5.

Shared conversations

Comments and mentions let teammates discuss a thread privately, with permission controls, instead of forwarding it or adding people on BCC.

Superhuman Mail

Split Inbox

Divides the inbox into separate tabs, for example mail from teammates, VIPs or specific tools, so each stream can be worked through on its own.

Keyboard shortcuts and Snippets

Most actions have a keyboard shortcut, and Snippets insert saved phrases, paragraphs or whole emails as you type.

Superhuman AI

Write with AI, Instant Reply, Auto Summarize and Auto Labels are on every plan. Auto Drafts, Ask AI and the Mail MCP server need Business or Enterprise.

Reminders, snooze and send later

Set a follow-up reminder that fires if nobody replies by a chosen time, snooze threads until they are needed and schedule when a message is sent.

Shared conversations and comments

Share a live view of a thread with teammates, comment on it, work on shared drafts and see when a colleague is already replying.

Calendar and scheduling

See the day's or week's calendar next to an email, create events, share availability and send booking links, with Zoom, Google Meet and Microsoft Teams links.
