Looking for a SaneBox alternative? Here’s the short list.
SaneBox is useful for sorting. You point it at your inbox; an AI tries to predict what matters. When the prediction is right, the inbox feels clean. When the prediction is wrong, real email gets buried in SaneLater or SaneBlackHole and you miss it.
Rythm takes a different approach. Rythm doesn't try to guess what matters. It checks your guest list. If you're not on the list, you're asked to put a small cover charge on the line (about four cents) that goes straight to the recipient's wallet. A simple gate at the door instead of a second pile to sort.
SaneBox sorts your noise. Rythm prices it.

Why Rythm is worth considering
- About four times cheaper per year than SaneBox, and the subscription can pay for itself through cover charges.
- Nothing gets buried. The guest list is a list you can see and edit; no AI decides for you.
- Works with the Gmail or Outlook inbox you already use.
- When a stranger pays the cover charge, the money settles to your wallet, not to us.
Frequently asked
Does Rythm do everything SaneBox does?
No. SaneBox has multi-folder sorting (SaneLater, SaneBlackHole, SaneNoReplies, snooze). Rythm is a single gate: on the guest list, or pay the cover. If what you want is sorting subscriptions you opted into, SaneBox is a better fit.
Can I run SaneBox and Rythm together?
Technically yes; they run at different layers. Most people pick one. Start with Rythm if your problem is strangers finding your address. Add SaneBox only if you also need newsletter triage.
Why is Rythm so much cheaper?
Rythm is structurally lightweight. A fast, deterministic, in-memory check (paid, or on your guest list?) replaces AI inference, threat-intel feeds, and model training. Less compute, less infrastructure, less cost. One plan, no upsells, no seat model.
Does Rythm read my email like SaneBox does?
Rythm checks unknown-sender messages for one thing (a valid cover-charge payment proof) then discards the content. It does not train a model on your mail.
What about AI-written cold outreach?
Rythm is a bouncer, not a lie detector. If the sender cared enough to pay the cover charge, the email gets through, whether a human or AI wrote it. Rythm filters for intention, not content.
