The Inbox Zero Stack That Actually Works
Superhuman for replies. Readless for newsletters. SaneBox for filtering. Inbox Zero without the relapse.
3 focused tools, one clean workflow. No more newsletters clogging your action inbox or “read later” guilt.
Why Traditional Inbox Zero Fails
Newsletters Kill Inbox Zero
30-50% of inbox volume is newsletters you plan to “read later.” They block triage and pile up guilt.
Mixed Intent
Actionable emails live next to FYI content. You lose the thread, miss replies, and never read the research.
Context Switching
Every time you open a newsletter, you abandon the inbox-zero flow. Regaining focus takes 23 minutes.

Your Inbox Flow After the Stack
Action Inbox
Superhuman handles replies, scheduling, and collaboration. Every email left inside is actionable.
Newsletter Lane
Newsletter subscriptions go directly to Readless. AI compresses TLDR, Morning Brew, industry memos, and long-form essays into one digest.
Noise Sandbox
Cold outreach and promos skip both inboxes. Process them weekly or never—without hurting Inbox Zero.
