PerkZilla

PerkZilla runs the kind of campaign where a subscriber gets something for referring others: a tiered reward ladder, a share link per person, and a leaderboard if the audience responds to one. It sits on a landing page or inside an email sequence and reports who actually brought somebody. Rewards can be digital goods, discounts or access. The pricing is flat rather than metered on list size, which is unusual in this category.

Three tiers at $29, $49 and $99 a month, separated by campaign and participant volume rather than by mechanism. Each card carries a line about paying for itself after one, two or three leads, and the page footnotes that as arithmetic against an average cost per lead of $33.40 taken from named third parties, which is a comparison rather than anything charged here. No free plan or trial is stated on the page.

Somebody running a launch, a waitlist or a newsletter push who wants the audience doing the sharing and needs to know who actually delivered. The flat price makes it predictable for a list that is growing fast, since nothing reprices as subscribers arrive. A business wanting referrals tied to purchases rather than signups needs affiliate software instead, which is a different mechanism.
