Ask HN: Monetizing a mailing list

[j_lagof]

Hi HN,

I run a few popular mailing lists (in their respective areas) and I was thinking on adding small ads at the bottom of every post (related to the topic of the list).

Is there such a service anywhere? Something like adsense for emails? ( not necessarily mailing lists) Maybe another ideas on how to monetize it?

Do you know CPA? This should convert well for you.

But is there any company offering that? Tracking that via a mailing list is much harder...
