inboxbid

InboxBid is a permanent newsletter leaderboard where operators bid for ranked visibility. Spots are never removed, so your listing stays live indefinitely once you've claimed a position.

The bidding model is straightforward: new spots start at $1, and you only pay the difference between your current bid and the position you want to take. This means climbing the rankings costs less than starting from scratch each time.

For newsletter operators looking for low-cost, persistent exposure, this offers a simple alternative to paid ads or sponsorships. Your listing includes a description, link, and timestamp — giving potential subscribers a quick snapshot of what you publish.

Already listed? You can restore your listing and pay only the incremental difference to move up. This makes it easy to maintain or improve your ranking without paying the full amount again.

The competitive format creates a natural incentive to stay visible — if someone outbids you, they take your spot. This keeps the leaderboard active and gives smaller newsletters a genuine shot at top placement for just a few dollars.
