Canary Mail vs Newton Mail

Canary Mail

• One mail app across Mac, iPhone, Windows and Android devices
• People who want PGP-encrypted email without a separate tool
• Buyers who prefer a one-time lifetime license to a subscription

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

Canary Mail

• It is a mail client, not a provider: it connects to existing accounts and does not create addresses or host mail.
• Apps are listed for macOS, iOS, Windows and Android only. There is no web or Linux version.
• AI Copilot, the calendar and Send Later need Growth, while PGP, SecureSend and phishing protection need Pro+ at $100 per year.
• There is no monthly billing. Paid plans are yearly or lifetime, bought inside the app, and the Free plan is limited to 2 devices.

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.

Canary Mail

Unified inbox for every account

Reads Gmail, Outlook, iCloud, Exchange, Yahoo Mail and other IMAP accounts in one inbox. Unlimited mail accounts are included on the Free plan.

AI Copilot

Drafts replies, suggests subject lines, rewrites messages in a chosen tone and summarizes long threads. It is part of Growth, and Canary says email is not used to train AI models.

Read receipts, snooze and Send Later

Lite read receipts, snooze, pinning and templates are free. Full read receipts and Send Later need Growth. A Chrome extension offers read receipts only.

PGP encryption and SecureSend

Pro+ adds PGP end-to-end encryption and SecureSend, which sends password-protected messages that can be set to expire.

Phishing and impersonation protection

Pro+ alerts you to suspicious links and spoofed senders and adds impersonation detection and misdirection prevention.

Calendar and scheduling

Growth includes a built-in calendar with scheduling tools, so meetings are handled in the same app as mail.

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.
