Best Popunder Ad Networks [2026]

Popunder ad networks connect two sides of the digital advertising ecosystem: advertisers looking to reach new audiences and publishers looking to monetize their website traffic. While both work with the same advertising format, their goals, priorities, and expectations are very different.

For advertisers, the focus is on reaching the right audience, generating conversions, and getting the best possible return on ad spend. Publishers, on the other hand, care about maximizing revenue while maintaining a good user experience and protecting the value of their website traffic.

In this guide, we’ll explain how popunder ad networks work from both perspectives, what advertisers and publishers should look for when choosing a network, and how the right approach can help each side get better results.

What is a Popunder Ad?

Unlike a popup, it never interrupts the browsing session in progress, which is why popunders tend to post higher engagement and lower perceived intrusiveness than popups, even though both fall under the broader “pop” ad category.

Why Do Popunder Ads Still Work in 2026?

Popunder traffic keeps its place in the media buying stack for a few concrete reasons:

• Guaranteed full-page visibility. Every impression is a 100%-viewability, full-screen exposure, there’s no “below the fold” problem.
• Low CPMs relative to other formats. Popunder inventory is typically priced well below native or in-page push, so it scales cheaply even on tight budgets.
• Ad-blocker resilience. With ad-blocker adoption estimated above 40% of internet users globally, popunders, which don’t rely on standard banner ad slots, see less blocking than conventional display formats.
• Strong fit for high-volume verticals. Gambling, betting, dating, sweepstakes, VPN/utilities, and finance offers convert well off a single, uncluttered full-page exposure, which is exactly what a popunder delivers.

How Do You Choose a Popunder Ad Network?

Before comparing specific networks, it helps to know what actually separates a good one from a mediocre one. Evaluate any popunder network against these criteria:

1. Traffic volume and GEO coverage: daily impressions, number of countries, and depth of coverage in the GEOs you actually target (Tier-1 vs. Tier-2/3 volume varies a lot between networks).
2. Targeting granularity: GEO, device, OS, browser, carrier, connection type, and dayparting all affect how tightly you can control spend.
3. Anti-fraud tooling: bot filtering and traffic verification, since popunder inventory has historically attracted more low-quality sources than other formats.
4. Pricing model and minimum spend: CPM, CPC, or automated bidding (e.g., target-CPA), and how low the entry deposit is for testing a new network.
5. Approval speed and support: how fast campaigns get moderated, and whether you get a dedicated account manager or ticket-queue support.
6. Payout terms (for publishers): minimum withdrawal, payment methods, and payout frequency, if you’re monetizing traffic rather than buying it.

Best Popunder Ad Networks in 2026

Volume and pricing figures are self-reported by each network and can shift; confirm current numbers on the network’s own site before budgeting a campaign.

Mondiad

Mondiad is a self-serve, multi-format ad network built by the original team behind PopCash, one of the earliest dedicated popunder networks. That popunder heritage is reflected in the platform today: alongside classic push, in-page push, native, and banner formats, Mondiad runs popunder as a first-class format aimed at high-volume, full-page campaigns, particularly effective for scaling into Tier-2 and Tier-3 GEOs.

For advertisers, campaigns run on CPM, CPC, or TargetCPA (automated bidding toward a target cost-per-acquisition), with a $50 minimum deposit and approval typically inside an hour. Targeting covers country, device, OS, browser, carrier, language, and traffic type, with direct integration into trackers like BeMob for campaign-level attribution.

For publishers, popunder tags require just a short code snippet with no layout changes, daily payment requests from a $10 minimum, and support available around the clock.

Best for: advertisers and affiliates who want to test popunder traffic without leaving a platform that also covers push, native, and banner, useful if you’re running the same offer across multiple formats and want unified reporting.

PopCash

PopCash has been running as a dedicated popunder network since 2012, which makes it one of the longer-standing names on this list, and the same team behind it went on to build Mondiad. Where Mondiad expanded into a multi-format platform, PopCash has stayed focused on a single format: popunder, for both advertisers and publishers.

For advertisers, campaigns run on CPM with a $5 minimum deposit, one of the lowest entry points among the networks here, making it an easy add to a testing rotation alongside larger platforms. Targeting covers geo, device, OS, browser, and traffic type, with a self-serve dashboard for setting up and monitoring campaigns.

For publishers, integration is a single code snippet with no layout changes required, and payouts are processed daily once a $10 minimum balance is hit, with support for PayPal, Skrill, Paxum, and several other payment methods. Traffic is checked for quality before each payout, which helps keep the publisher pool relatively clean for advertisers buying in.

Best for: advertisers who want a low-cost way to test popunder traffic outside their main platform, and publishers who want a simple, popunder-only setup with fast, frequent payouts.

Blockchain-Ads

Blockchain-Ads is the audience-based option in this list. It is an advertising platform built for crypto, iGaming, finance, and related industries, running on the NEXUS Ad Exchange with its own first-party data, so campaigns reach people by interest, on-chain behavior, and buying intent across display, native, video, and full-screen in-app placements.

Buying runs on CPM, CPC, and CPA, with inventory verified through DoubleVerify so budget reaches real users on clean placements. Campaigns are set up and scaled by in-house media buying teams, up to 500 live at once per account, and each one reports across 8 attribution dimensions with export and API into Voluum or AppsFlyer.

The outcomes hold up in regulated markets: Stake.com delivered 1,128 first-time depositors across 13 markets at 2.5x ROAS, and Coinbase brought in 8,214 new traders and $6.97M in trading volume.

Best for: advertisers in crypto, iGaming, finance, and related industries running full-page and high-impact formats who want every impression matched to a verified, high-intent audience.

PropellerAds

PropellerAds is one of the largest multisource ad platforms by volume, with popunder as one of several formats alongside push and native. Its AI-based bid optimization and geotargeting are frequently cited by publishers as delivering above-average eCPMs, particularly for mobile apps, e-commerce, and finance verticals.

Best for: advertisers prioritizing raw scale and automated optimization over a specialized popunder focus.

RichAds

Originally known for push traffic, RichAds expanded into popunder in 2019 and now runs 5+ billion daily impressions with AdScore-verified traffic. Its automation tools skew toward affiliates running performance campaigns who want the platform handling bid adjustments in real time.

Best for: performance marketers who want automated campaign scaling with a higher minimum deposit ($250) in exchange for tighter fraud filtering.

HilltopAds

HilltopAds pairs large-scale popunder inventory (270+ billion monthly impressions) with automated campaign checkups, reducing the need for manual bid management. Weekly publisher payouts start at $20.

Best for: publishers and advertisers who want to set optimization rules once and let the system handle ongoing adjustments.

Adsterra

Adsterra runs popunder as one of its core formats across 25+ billion monthly impressions, with one of the fastest publisher approval processes in the space (around 10 minutes) and a low $5 minimum payout.

Best for: publishers who want the fastest path from signup to live monetization.

ExoClick

Running since 2006, ExoClick is a long-standing name in adult and entertainment traffic, where popunder is consistently one of its top-performing formats.

Best for: advertisers and publishers specifically in adult verticals.

AdMaven

AdMaven has focused on popunder and push since 2010, with a particular strength in fill rates across Tier-3 GEOs where other networks sometimes struggle to deliver volume.

Best for: campaigns targeting utilities, sweepstakes, and finance offers in harder-to-fill geographies.

PopAds

PopAds is a popunder-only network, it doesn’t diversify into push, native, or other formats. That single-format focus is a limitation for publishers chasing higher blended eCPMs, but it remains a straightforward option for anyone who wants popunder exclusively and nothing else to configure.

Best for: publishers who want a no-frills, popunder-only setup.

Popunder Ad Networks Takeaway

Most of the networks above serve both sides of the market, but what “best” means differs depending on which side you’re on:

• As an advertiser, prioritize targeting granularity, minimum deposit, and how fast campaigns get approved, testing a new offer against multiple networks in parallel is common practice, so lower minimums let you test more networks at once.
• As a publisher, prioritize fill rate in your specific GEOs, minimum payout threshold, and payment method support, a network with excellent Tier-1 volume can still underperform for a site with mostly Tier-3 traffic.
