Shaded rows are where the two answers disagree and both listings have answered. A row where one side has not stated a fact is left plain, because silence is not a difference.
AdButler
Run your own ad server and keep the whole sale
AdButler is the software behind a direct ad sale rather than a network that finds the advertiser for you. You upload the creative, set the targeting and the flight dates, and the server counts what was delivered so both sides are looking at the same numbers. That matters to a publisher who has already sold the slot and does not want a third party taking a cut of it. The trade is obvious: nobody is filling your inventory, so the sales job stays yours.
Our note
Buy this when the sales conversation is already happening and the only question is how to serve and count what you sold. If you are still hoping somebody fills the space for you, an ad network costs nothing up front and this costs $179 a month before a single advertiser exists.
Swapstack
Newsletter sponsorships with a published fee
Swapstack introduces newsletter writers to the brands that want to advertise in them, and it is unusually direct about what it takes for doing so. A publisher joins for nothing and keeps everything on a deal they source themselves; the fee applies to campaigns Swapstack brought. Advertisers pay a share of spend instead. For a writer with a few thousand subscribers and no interest in cold email, that is the whole pitch.
