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.
AdPlugg
Ad serving that starts free and bills by impression
AdPlugg serves and reports on ads you sold yourself, with a WordPress plugin for sites that live there and tags for everything else. The free tier runs a hundred thousand impressions a month, which covers a small site outright. Above that the monthly fee is small and the real cost is metered per thousand impressions, published as a table rather than quoted. Nobody here is finding you advertisers.
Our note
Work out your monthly impressions before comparing this against AdButler or Broadstreet, because the flat-fee servers cost more at the bottom and stop surprising you at the top. AdPlugg wins for a site under a hundred thousand impressions by a distance, and the arithmetic reverses somewhere in the millions.
SparkLoop
Get paid for recommending other newsletters
SparkLoop turns a newsletter's own audience into revenue by paying it to recommend other newsletters, either inside the email or on the page somebody lands on after subscribing. The same network runs the other way, so a publisher can buy subscribers from it as well as sell them. Both sides sit on the free plan. It works with the mainstream sending platforms rather than replacing one.
