MailAdx vs LiveIntent for newsletter advertising
LiveIntent is a demand network built on email identity. MailAdx is an ad infrastructure platform. Both serve email ads — here's the fundamental difference.
LiveIntent operates a large demand-side network that matches advertisers to email inventory using its LiveConnect identity graph. Publishers integrate LiveIntent's tag and receive demand from LiveIntent's advertiser pool. The value proposition is instant access to programmatic demand without managing direct advertiser relationships.
MailAdx is infrastructure: you own the ad stack, connect to demand sources you choose, and set the terms. The MailAdx open-time ad server handles direct-sold deals, PMP deals, and OpenRTB programmatic demand — including, potentially, LiveIntent as a demand source connected via OpenRTB.
If you already have demand through direct deals or want to control your own ad business, MailAdx gives you the infrastructure to do that. If you want to immediately monetise a large list with zero setup, LiveIntent's network is a faster starting point — though the eCPM and revenue share terms are set by LiveIntent.
LiveIntent's LiveConnect identity graph is genuinely differentiated. By matching hashed email addresses against a deterministic ID graph built from people-based login data, LiveIntent enables audience targeting that doesn't rely on third-party cookies. For publishers with large general interest lists where audience targeting is a meaningful selling point, LiveConnect can lift CPMs meaningfully versus contextual-only demand. MailAdx uses subscriber email hashes for frequency capping and basic identity management — not the same depth of audience graph as LiveConnect.
Revenue share is a meaningful structural difference. LiveIntent's publisher terms are not publicly disclosed, but network monetisation models typically retain 30–50% of gross advertiser spend. MailAdx charges a flat serving fee and pays the publisher the remaining advertiser spend minus that fee. A publisher generating $5,000/month in gross ad revenue on LiveIntent at a 40% network take-rate keeps $3,000. On MailAdx at $0.40 CPM serving fee with the same impression volume, the publisher keeps approximately $4,800. The exact numbers depend on your impression volume and negotiated terms, but the structural difference compounds at scale.
Publishers with audiences over 100,000 subscribers will find LiveIntent easier to activate for immediate demand than building out direct relationships from scratch. The question isn't which is better in isolation — it's which suits your current operational stage. LiveIntent works best as a plug-and-monetise solution for large general lists. MailAdx works best when you have direct demand to run alongside programmatic fill and want to optimize for publisher economics rather than publisher convenience.

Where MailAdx wins
Infrastructure you control vs network you join
LiveIntent is a demand network: you integrate their tag and they fill your inventory from their advertiser pool on their terms. MailAdx is infrastructure you own: you configure floors, approve advertisers, and connect to whatever demand sources you choose — LiveIntent included, via OpenRTB. The distinction matters when revenue share terms change or you want to negotiate direct deals.
Publisher portal and reporting
MailAdx gives publishers a dedicated portal with placement management, floor controls, and granular delivery reporting per placement, per send, and per advertiser. LiveIntent's publisher-facing reporting is focused on their network's aggregated metrics, not your individual placement economics.
Transparent pricing, no revenue share
MailAdx charges a per-impression serving fee; publishers keep 100% of advertiser spend above that. LiveIntent takes a revenue share from every impression — terms that can change and are not publisher-controlled.
Direct advertiser relationships
With MailAdx, advertisers can run campaigns directly against your inventory through the self-serve DSP. You build the relationship and set the rate. With LiveIntent, all advertisers go through LiveIntent's network, so you never build direct relationships with the brands spending on your audience.
When LiveIntent is the better choice
- You have a large, broadly-addressable email list (100k+) and want instant access to LiveIntent's advertiser pool without any sales work.
- You want identity-based audience targeting using LiveConnect's deterministic email ID graph.
- You're a pure publisher with no interest in also serving advertisers — you just want demand, not an ad platform.
- You need to be live tomorrow with zero configuration — LiveIntent's tag integration is simpler than running a full ad stack.

Frequently asked questions
Can I use LiveIntent as a demand source inside MailAdx?
Yes. MailAdx supports OpenRTB integrations, so LiveIntent can be connected as a programmatic demand tier in your waterfall alongside direct-sold deals and other exchanges.
Does MailAdx replace LiveIntent entirely?
Not necessarily. Many publishers use MailAdx as their ad infrastructure and connect LiveIntent as one demand source. MailAdx gives you control over floors, reporting, and direct deals; LiveIntent provides instant network demand.
Which platform has better publisher economics?
MailAdx charges a flat per-impression serving fee with no revenue share — publishers keep 100% of advertiser spend above the fee. LiveIntent takes a revenue share on every impression, with terms set by the network.
What is LiveConnect and how does it compare to MailAdx's identity approach?
LiveConnect is LiveIntent's deterministic identity graph, built from hashed email matches across publisher login data. It enables buyer-side audience targeting across LiveIntent's network. MailAdx uses subscriber email hashes for frequency capping and suppression within a single publisher's campaigns — useful for avoiding ad fatigue, but not a cross-publisher identity network. For publishers whose main goal is household-level frequency control across their own sends, MailAdx is sufficient. For publishers who want to sell 'audience segments' to buyers at a CPM premium, LiveConnect's deeper graph is a genuine advantage.
What list size do I need before MailAdx makes sense over LiveIntent?
MailAdx is viable from day one for direct-sold campaigns — list size doesn't determine whether the infrastructure works. For programmatic fill, meaningful CPM competition typically requires 2,000–5,000 monthly opens per placement. Below that threshold, LiveIntent's network demand can generate more revenue per send because their buyer pool fills small inventory at competitive CPMs. Above 50,000 monthly opens, the economics shift decisively toward owned infrastructure — the revenue share that's tolerable at $500/month becomes significant at $5,000/month.
