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.
AdvertiseCast
Podcast ad marketplace with published rates
AdvertiseCast is the rare ad network that prints its rate card in public, so a podcaster can work out what an episode is worth before talking to anybody. Shows list, advertisers book, and host-read spots are matched against downloads. Its rates are an industry average rather than an offer, and a small show will be quoted under them.
Our note
The rate table is worth reading whether or not you list here, because it is the clearest public benchmark for what podcast advertising is worth. Use it to sanity-check any sponsorship offer you get directly.

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.
