Here are five of the best email clients for macOS right now, plus commentary on their strengths and trade-offs:
Spark
- The Standout Feature: Smart Inbox and collaborative tools. It automatically sorts your emails (Personal, Notifications, Newsletters) so you only focus on what matters. Its team-focused features are excellent for small businesses or groups working together on email.
- The Trade-off: The best collaboration features and unlimited use are behind a subscription, and some users report occasional sync delays with certain providers.
Canary Mail
The Standout Feature: A strong blend of security and modern AI. It’s perfect if you handle sensitive information and want the assurance of PGP and other encryption, while also using AI to speed up drafting and summarizing emails.
The Trade-off: The most powerful AI and security features are often only available in the paid tiers, making the free version less compelling than Spark or Apple Mail.
Mimestream
- The Standout Feature: The ultimate client for control and integrations. Designed for Gmail with good sync for google ecosystem.
- The Trade-off: Subscription based only supports Gmail accounts. Not universal with other IMAP clients.
Mailspring
- The Standard Feature: Open Source / Free Features lightweight
- The Trade-off: Pro version you have to pay for it. Free version limited
Microsoft Outlook
- The Standout Feature: Best for a professional, all-in-one hub. It’s ideal for those deeply embedded in the Microsoft ecosystem (Exchange servers, OneDrive, Teams). The integrated calendar and task manager make it a true productivity suite.
- The Trade-off: Can feel too feature-heavy and complex for casual users, and its full potential is only realized with a Microsoft 365 subscription.
My Recommendation (2025)
- Best for productivity and collaboration: Spark — if you want a modern, team-friendly app.
- Best for security and privacy: Canary Mail — strong encryption + AI.
- Best for Gmail users: Mimestream — for a native Gmail-API-based experience.
- Best cross-platform power user option: Mailspring — flexible, clean, very capable.
- Best for business / work use: Outlook — especially if you’re already using Microsoft services.
