Clean Email: Batch Cleanup and Automation Rules

Agentys: Beyond Sorting — AI That Actually Replies

Picking the Right Tool for Your Inbox

SaneBox excels at ongoing AI filtering. Clean Email excels at batch cleanup and rules. Both are solid inbox organizers — but neither writes your replies. Agentys goes further by sorting your inbox and drafting complete responses overnight matching your tone. Agentys does not replace bulk cleanup (if you have 10,000 unread emails, Clean Email is genuinely the best first step). But if sorting is your ongoing problem, SaneBox or Clean Email will help. If writing is your problem, Agentys is the smarter choice. Both SaneBox and Clean Email have loyal user bases for good reason — they solve real problems. The limitation isn't quality; it's scope.
