PopCash

PopCash is a popunder advertising network established in 2012. It sells one format, popunder advertisements, through a self-serve platform where the advertiser has full control over a campaign: create it, manage and edit it, pause it or delete it.

The network reports more than four billion monthly visitors and over ten thousand running campaigns, with worldwide coverage and what it calls a vast traffic inventory. New campaigns go through review, and the site states that pending campaigns are usually approved in one hour or less.

Targeting covers GEOs, devices, operating systems, carriers and browsers, plus additional custom parameters.

The entry threshold is low. The minimum deposit is $5, made through PayPal, Paxum or wire transfer, and the advertiser page lists PayPal, Paxum, Skrill, wire transfer, Payoneer and Capitalist among the accepted funding methods.

The site does not name a pricing model or preferred verticals, so those fields are left empty in this profile.
