Inboxbid is a public leaderboard where newsletters are ranked by the total their owners have paid. Bids start at $1. Pay more than the newsletter above you to take its place, or make a smaller bid and join further down the board. Every payment adds to your running total, so moving up later costs only the difference.

The ranking formula and every listing's total are public. There are no editorial picks or a hidden algorithm. Your listing does not expire, and being outbid moves it down rather than removing it. Eligible listings also receive a public detail page and a place on a category leaderboard. We built Inboxbid after submitting our own products to directories where it was never clear why one listing appeared above another.
