SaneBox

What Is SaneBox?

SaneBox is an AI email filtering service that works at the server level, between your email provider and your inbox. It analyzes your email history, learns which senders and threads you actually engage with, and automatically routes low-priority messages out of your main inbox into separate folders.

Because it works via IMAP rather than as a plugin, SaneBox is compatible with every email client: Gmail, Outlook, Apple Mail, Spark, Superhuman, and any mobile app. You don’t change how you use email. It just gets quieter.

How It Works

SaneBox creates a set of smart folders in your existing email account:

SaneLater holds emails that are probably not urgent: newsletters, notifications, promotional messages, and anything from senders you rarely reply to. You review it when convenient, not constantly.

SaneNews captures email newsletters specifically, keeping them separate from other low-priority messages.

SaneBlackHole is permanent unsubscribe by drag-and-drop. Drag any email there and SaneBox automatically deletes all future messages from that sender before they reach you.

SaneReminders lets you snooze emails back to your inbox at a specific time. Forward an email to tomorrow@sanebox.com or 2weeks@sanebox.com and it reappears when relevant.

SaneNoReplies tracks emails you sent that haven’t received a response, so follow-ups don’t fall through the cracks.

The AI Learning Loop

SaneBox gets smarter over time. Every email you move from SaneLater back to your inbox is a training signal: this sender is important, prioritize them. Every email you leave in SaneLater confirms the classification was correct. After a few weeks, misclassification becomes rare for most users.

Who It’s For

• Executives and founders receiving hundreds of emails daily who need their inbox to surface only what matters
• Knowledge workers who have tried inbox zero and abandoned it because the maintenance overhead was too high
• Anyone in customer-facing roles who needs to distinguish client emails from internal noise instantly
• Remote workers managing communication across time zones who need async email to be less overwhelming

Pricing

• Snack: $7/month, 1 email account, core folders
• Lunch: $12/month, 2 accounts, all features
• Dinner: $36/month, 4 accounts, full feature set

All plans include a 14-day free trial. Annual billing reduces costs by roughly 20%.

Verdict

SaneBox solves email overload without requiring you to change your tools, build complex filters, or adopt a new system. The AI does the sorting, you do the actual work. For anyone whose inbox is a source of daily stress, the trial will convert you in the first week. The SaneBlackHole alone is worth the subscription for most people.

Frequently Asked Questions

Does SaneBox work with Gmail? Yes. SaneBox works with Gmail, Outlook, iCloud, Yahoo Mail, Fastmail, and any IMAP-compatible email provider. It is also compatible with all email clients since it operates at the account level.

Is SaneBox safe? SaneBox accesses your email via IMAP to read subject lines and sender data to classify messages. It does not read email body content for filtering purposes. The company has been operating since 2010 with a strong privacy track record.

What is SaneBlackHole? SaneBlackHole is a special folder that acts as a permanent unsubscribe. Drag any email into it and SaneBox automatically deletes all future emails from that sender before they reach your inbox.

Can SaneBox misclassify important emails? Occasionally, especially in the first few days. If an important email lands in SaneLater, moving it back to your inbox trains SaneBox to prioritize that sender. Most users report accurate sorting within 1-2 weeks.

Does SaneBox replace email unroll tools like Unroll.me? SaneBox is more comprehensive. It handles newsletters, notifications, low-priority senders, snoozing, and follow-up tracking, while Unroll.me only handles newsletter subscriptions.
