What Should I Look for When Choosing an Email Tool?

Here are the key insights you need to choose between Sanebox and Superhuman:

• Workflow Style: Do you need a complete email client replacement built for sheer speed (Superhuman)? Or do you prefer a background service that cleans up your existing inbox with smart folders (Sanebox)?
• Cost vs. Value: How much time do you save? Superhuman’s high price is only worth it if you process hundreds of emails daily and need the fastest email experience. Sanebox pricing is much gentler for budget-conscious users.
• Compatibility: Sanebox works with virtually any email provider (Gmail, Outlook, etc.). Superhuman only works with Gmail and Outlook.
• AI Focus: Do you want AI that writes and drafts (Superhuman AI features)? Or AI that sorts and organizes (Sanebox)?
• Keyboard vs. Drag-and-Drop: Superhuman relies entirely on keyboard shortcuts and the command bar. Sanebox relies on simply dragging and dropping unimportant emails into different smart folders.

Final Verdict

The winner is Sanebox.

We pick Sanebox because it offers easy access to a clean inbox.

Sanebox is winner for most people.

Superhuman work is best for power users who need every second of speed.

However, Superhuman’s high price and steep learning curve for features like calendar management and AI search are significant drawbacks.
