See what unknown-sender cover charges could net you. Plug in your traffic; we handle the math.
Each cover charge settles directly to your wallet. Rythm keeps a small safety buffer to cover routing fees on the payment rail; the rest is yours.
Math: senders per day x cover charge x pay-through rate, scaled to 30 days and 365 days.
All calculations happen in your browser. We don’t store inputs.
How many strangers email you a day, what cover charge you set, and what fraction of strangers you expect to actually pay.
Daily, monthly, and annual net dollars from cover-charge payments at that pay-through rate.
A realistic floor and ceiling for what unknown-sender traffic could turn into.
Use 12 senders a day and 25% pay-through if you have no idea where to start.
We do the multiplication in your browser. No traffic data leaves the page.
A directional answer: is this a meaningful sum or a rounding error.
Bump the cover charge to 25 cents or a dollar to see how the answer scales.
Higher cover charges discourage more strangers, so the pay-through rate drops at the same time. Most users keep four cents.
Permission to set whatever cover charge feels right for your inbox.
This is structural, not guaranteed. Most strangers will not pay, even at four cents. The pay-through rate slider is a guess, not a promise. The cover charge is not the main product value (the main value is the bouncer at the door, not the till behind it). Treat any number this tool returns as a directional estimate, not a forecast. The tool also assumes a steady inbox; in practice, traffic spikes around launches, press hits, and conference seasons. Numbers could swing 5x in either direction in a given month.
