Newton Mail vs Superhuman Mail

Newton Mail

• People who want the same mail app on Mac, Windows, iPhone and Android
• Knowing whether a sent email was opened, and by which recipient
• Small teams that share a thread or a support@ address

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)

Newton Mail

• The Free plan is limited to 2 email accounts, 15 read receipts a month, 3 templates and 20 AI actions a day.
• Shared inboxes need the Team plan, which has a 2-seat minimum and is offered through a Request Access button.
• There is no webmail: the web portal is for account and settings management only.
• A Linux build is linked from the homepage, but the pricing page lists apps for Mac, Windows, iPhone and Android only.

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.

Newton Mail

Read receipts

Sent emails are tracked without any extra step, with per-recipient open tracking. The Free plan includes 15 read receipts a month and Pro makes them unlimited.

Snooze and send later

Snooze takes an email out of the inbox until a time you choose and syncs across devices. Send Later schedules a message to arrive at a set time.

Shared threads

Share a whole conversation with teammates, comment privately beside it and let authorized people reply from your address, with an activity log. Creating shared threads needs Pro.

Newton AI

The Today view triages the inbox by priority and Compose helps write emails. Usage is capped at 20 AI actions a day on the Free plan and 200 on Pro.

Connected apps and MCP server

Save an email to Todoist, Evernote, OneNote, Trello or Asana in one click, and use the MCP server to search, read, draft and schedule email from Claude and other AI assistants.

One inbox for Gmail, Outlook and IMAP

Works with Gmail and Google Workspace, Outlook and Microsoft 365, and IMAP accounts such as iCloud, Yahoo and Fastmail, with full-text search across every account at once.

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.
