SaneBox review

SaneBox is a sorting tool, not a writing tool, and that is its appeal. It connects to your email account on the server side, so it works with any email client, and filters messages by importance, moving low-priority mail into SaneLater and learning where to file things as you correct it. Email Deep Clean purges thousands of old messages in minutes, SaneBlackHole stops a sender for good, SaneNoReplies tracks unanswered threads and a Daily Digest shows what was filtered. The Snack plan costs $4.54 per month billed every two years and covers one account with two power features; Lunch at $7.46 covers two accounts and six features; Dinner at $22.04 covers four accounts and every feature. The gap for busy professionals is drafting: SaneBox does not write replies or summarize threads with generative AI, so it pairs best with Gemini, Copilot or a writing tool if you want both.
