Inboxbid is a permanent bidding leaderboard for email newsletters. One number decides every rank: the total that listing has paid. Bid more than the newsletter above you, and you take its seat. Bid less, and you land wherever your number falls — a smaller bid is a lower seat, not an error.

How the bidding works

Bids start at $1. No plan, no subscription, no minimum spend to get on the board.
Passing a seat costs $1 more than the total it holds. Matching isn't passing — on a tie, the older listing keeps the higher rank.
Your bids accumulate. Every payment adds to one running total, so climbing later costs only the gap between what you've already paid and the seat you want. You never pay the full amount twice.
Nothing expires. A rank is not a rental. The only way to lose a seat is to be outbid.

What a listing gets you

A ranked spot on the main board and in one of 47 category leaderboards — AI, Finance, Design, Real Estate and 43 more, each ranked by what its listings have paid.

Who it's for

Newsletter operators who want a durable, public signal of where they stand — one that keeps standing after the campaign budget runs out.
