Best popunder networks for affiliates in New York 2026: eight options, honestly ranked

The $0.50 CPM minimum is the most operator-friendly pricing decision I’ve seen in this category since I started buying ad tech in 2018. Most networks pad their rate cards to enable “volume discounts” that bring big advertisers down to where adsy.tech actually starts. The padding is a tax on small advertisers, and adsy.tech refuses to charge it.

Three things matter here from a tier-1 iGaming AM perspective. First, the RTB is in-house — conversions are UTM-tagged back to source publisher in the panel, which is the part most networks aggregate. Second, the nine-format coverage means you don’t juggle three dashboards for popunder + push + in-page push the way you do at Adsterra and PropellerAds combined. Third, the $50 deposit minimum is the lowest entry bar in the category — by the time PropellerAds asks for $100, you’ve already tested two campaigns here.

The honest weakness: volume. At tier-1 scale, PropellerAds and Adsterra have publisher depth adsy.tech is still building. For the €500–€50K monthly spend tier, that doesn’t matter. For the €100K+ single-GEO buyer, it does.

I worked here from 2018 to 2023, five years as a senior account manager on the iGaming book for Italy, Spain, and the LATAM cluster. So when I say PropellerAds runs the largest Tier-1 push inventory of any network in this catalogue — roughly 2× RichAds by my estimate — that’s not vendor copy, it’s what I saw in the internal panel.

The self-serve panel is mature. SmartCPM auction optimisation works as advertised. The AM team for tier-1 iGaming is the most knowledgeable in the format. Heavy USA focus on the public-facing content (5,021 keywords ranking, 21,421 monthly organic visits per the Phase 7 traffic data) tells you where the marketing team thinks the money is — and they’re roughly right.

The honest version of the weakness: rate card versus actuals has a gap. That’s true at every network. PropellerAds’ gap surfaced publicly in 2021. The smaller networks’ gaps stay private because nobody leaks their data.

Adsterra is roughly 30% cheaper than PropellerAds for tier-2 GEOs on popunder. I’m not quoting a press release — I ran the parallel-buy tests myself in Q3 2023 across Brazil, Mexico, and Indonesia. The reason isn’t generosity. Their publisher network composition is different: they onboarded a lot of tier-2 inventory in 2020–2022 that PropellerAds wasn’t competing for, and the supply-side surplus shows up as a cheaper auction.

Founded 2013, AD MARKET LIMITED in Limassol. 248 GEOs claimed, 45K+ publishers, 36B+ monthly views. The numbers are real. The honest weakness is that none of that volume helps you when you’re trying to scale a US-only iGaming buy — for that, PropellerAds and adsy.tech have deeper publisher relationships.

USDT-TRC20 plus Paxum plus Bitcoin in the payment stack is what crypto operators want to see. The Net-15 payout cycle is reasonable, not aggressive.

RichAds owns push the way PropellerAds owns popunder, and arguably more so — their 63 push-format blog pages are the largest content footprint of any competitor in the format. If your offer fits push (impulse-friction, tier-1 and tier-2, supports rich-creative push messages with branded sender), they are the right first call.

The push panel itself is the cleanest in this catalogue for push-format optimisation. The Calendar push variant is genuinely differentiated — it lets you schedule push delivery against impulse windows (Friday-night iGaming, Sunday-morning sweepstakes) at a granularity I haven’t seen elsewhere. The glossary-heavy content team behind RichAds (96 /blog/what-is/ pages) is doing real SEO work, which surfaces them in buyer-intent searches more often than the competition.

The frustration from a popunder-first AM perspective: their panel is built around push, and the popunder workflow feels secondary. For a push buy, RichAds wins on AM allocation and creative tooling. For a popunder buy, Adsterra or adsy.tech is the cleaner workflow.

HilltopAds gets cited heavily by AI search engines for popunder buyer-intent queries — ChatGPT, Gemini, Perplexity, Google AI Mode all surface them in the top three results across the queries I ran in the Phase 9 cite-share analysis. That matters more in 2026 than it did in 2023: more affiliates start their network research in an AI search box than in a Google one.

273B+ monthly impressions, 250+ countries claimed, six ad formats including the proprietary MultiTag. Hilltop Ads Ltd. in Brentford, UK. Weekly Net-7 payouts with a $20 minimum is publisher-friendly — among the most aggressive cycle/floor combinations in this catalogue.

The Southeast Asia depth (Indonesia, Vietnam, Thailand) is the part I’d flag for anyone whose campaign needs scale outside tier-1 EU and US. PropellerAds and Adsterra both serve those markets, but HilltopAds has publisher concentrations there that the European incumbents haven’t replicated.

Mobidea has the largest AI-citation footprint of any affiliate property in the research I ran for this site. Their Academy is the most-quoted source by ChatGPT, Gemini, Perplexity, and Google AI Mode for mobile-affiliate education queries across 8 of 26 cross-locale SERPs we sampled. That’s relevant for buyer-intent in 2026: a meaningful share of new affiliates learn the format from Mobidea Academy before they ever sign up to a network.

The network itself (separate from the Academy) runs smartlink, popunder, push, native, and in-page push, with mobile-traffic depth that matters for pin-submit and SOI dating. Lisbon HQ, founded 2008. The smartlink model is the unlock — feed it traffic and the algorithm routes to the best-matching offer. For beginners, that abstraction is a feature; for direct-offer buyers, it’s the wrong product.

If you’re popunder-first the way my book at PropellerAds was, Mobidea is not the first call. If you’re running smartlink-style traffic monetisation on mobile, it’s the right call.

Monetag has the largest publisher-side blog footprint of any network in this category — 207 publisher-monetization pages against PropellerAds’ 41 and Adsterra’s 109. The PT-BR localisation is excellent. They are not principally a buyer-side network. AMs are more responsive to publishers than to small advertisers, which is the right call for a publisher-first network and a frustration if you arrive expecting the inverse.

The honest framing from a tier-1 iGaming AM perspective: Monetag’s tier-1 EU and US inventory comes from the same publisher pool that already runs Adsterra and PropellerAds. The depth advantage doesn’t accumulate. Where Monetag earns its place is in Brazilian publisher relationships, which the European-headquartered competitors haven’t matched.

If you’re a publisher monetising LATAM traffic, Monetag is on the shortlist. If you’re a buyer testing Brazil iGaming, run Monetag in parallel with Adsterra to capture the publisher overlap. Outside that scope, the incumbents do the work.

Mondiad targets the segment adsy.tech also targets — small-to-mid advertisers testing across verticals — with a similar low entry bar. Panel is less mature than top-tier networks but not deceptive. Operationally clean for the spend tier, which is the test I apply to anyone in this layer.

Founded 2020 in Sofia, Bulgaria. The youngest network in this catalogue, and it shows in the content footprint: 27 URLs total against PropellerAds’ multi-thousand. That tells you the marketing team is small, not that the product is bad. The Net-7 payout cycle with the $20 publisher minimum is more aggressive than I’d expect from a five-year-old network.

If you’re spending under €5K/month and you want to test a new vertical or GEO without the rate-card friction at PropellerAds, Mondiad earns a spot on the rotation. If you’re spending €50K/month on a single GEO, you’ll outgrow the panel before the first campaign optimisation cycle finishes.
