Marketers are under more pressure than ever to deliver personalized, high-performing campaigns—while navigating tighter budgets, shifting privacy expectations, and fragmented tech stacks. Despite an explosion of tools and data sources, the fundamentals of marketing haven’t changed.
Every great campaign still starts with a simple question: Who are we trying to reach?
The answer depends on how well you understand your customers. Increasingly, that understanding is hampered by data silos, inconsistent identity signals, and disconnected workflows between planning, activation, and measurement. When those pieces don’t align, it leads to inefficient spending, incomplete insights, and missed opportunities.
To move forward, marketers need more than better tools—they need a more connected approach.
Start with a complete view of the customer
The foundation of effective marketing is understanding your audience—not just who they are, but what they care about and how to reach them across devices and platforms.
That starts with building a complete customer profile. For many marketers, this means linking persistent offline data—such as name and address—with fresh digital signals like device IDs and online behaviors. When combined, these elements provide a high-fidelity view of the customer that can be enriched with attributes like demographics, purchase behavior, and lifestyle interests.
This kind of profile doesn’t just help you understand people—it helps you build audience segments that actually perform. Whether you’re working with your own CRM data or third-party sources, the ability to create addressable segments that are both accurate and scalable is what separates good campaigns from great ones.
🛳️ That’s exactly what MMGY did for Windstar Cruises. By layering first-party data with behavioral and demographic insights, they built custom audiences that more than doubled campaign benchmarks.
🎮 Gaming platform Unity tapped into Experian audiences to understand player behaviors across web, mobile, and connected TV (CTV). These insights helped their advertisers reach gaming audiences more effectively—tailoring creative and delivery to real-world preferences, not assumptions.
Activate with precision, not just volume
Knowing your audience is only half the battle. The next challenge is reaching them—consistently and efficiently—across multiple channels.
This is where fragmentation can creep back in. All too often, marketers build audiences in one system, but activate in another, causing data loss and targeting mismatches. A more connected strategy uses the same identity and audience spine across planning and activation, reducing signal loss and improving accuracy.
👉 Curated private marketplaces (PMPs), for example, allow marketers to match high-quality audiences with premium inventory in a targeted, transparent, and efficient way. These deals let marketers align their spending with their goals—whether that’s lowering cost-per-acquisition or boosting reach in a key vertical.
Performance results are bearing this out:
When identity, audience, and inventory are aligned, everyone benefits—marketers, publishers, and consumers.
Measure what matters
Too often, measurement is treated as an afterthought. But in a connected campaign, it’s built in from the beginning.
By using consistent identity across planning, activation, and measurement, marketers can connect ad exposure to real-world outcomes—whether that’s an online conversion, an in-store visit, or a new customer relationship.
This kind of closed-loop measurement turns marketing into a learning engine. You don’t just see what happened—you understand why it happened and can use that information to improve the next campaign.
🛳️ In the case of Windstar Cruises, MMGY used Experian identity to precisely measure how digital ad exposures translated into bookings. That kind of visibility gives marketers more than a report card. It gives them the feedback they need to optimize smarter next time—and prove ROI every time.
The future is connected
To meet today’s demands, marketers need a new way of working—one that starts with a complete understanding of the customer, builds addressable audiences on a strong identity foundation, activates them precisely across channels, and measures impact in real time.
The marketers embracing this approach are already seeing results: stronger performance, more efficient spending, and deeper insights that power what comes next.
The future won’t be built on more tools—it will be built on more connection.

Email hashing was originally intended to be used as an email security feature that has ended up being a very powerful marketing tool. A hashed email is a cryptographic function that changes an email address to a random code which can be used as an anonymous customer identifier. This code is privacy-safe and cannot be traced back to the customer’s email address. However, this hashed email can function like a digital passport that traces every behavior and action a customer takes when logged into an account that is authenticated with an email, making hashed emails a goldmine for customer data. Today emails are used across traditional publishers and within the CTV ecosystem; tying them to more consumer touch points than ever before. Why the emphasis now? Cookies are on their way out the door and have been the primary way that many marketers have tracked their existing and potential customers. In order to replace this granular level of data, marketers are likely going to need multiple solutions. With so many cookieless solutions and IDs appearing in the marketplace, the mapping of the customer journey is bound to be fragmented. Relying on first-party data, such as hashed email, is just one way to reduce that fragmentation; as it can serve as an authenticated starting point for cross-device identity resolution that can be leveraged for targeting, personalization and measurement. How can Tapad + Experian help? Tapad + Experian's Hashed Email Onboarding is a privacy-safe way to connect consumer email addresses to their related digital devices and other digital identifiers through high precision probabilistic identity. By onboarding hashed emails and incorporating them within your Tapad Graph file you can: Build a more holistic view of individuals and households and their relationship to email addresses in your first-party data set Leverage these relationships for increased cross-device scale for targeting Employ personalization tactics at the household or individual level across devices Create new audience segments and look-alike models for cross-channel activation Design more inclusive measurement and attribution for customer journey mapping Tapad, a part of Experian has built a hashed email onboarding product feature that works with the existing flexibility of The Tapad Graph to deliver the most holistic consumer view, combined with the attributes you need, in the structure that works best for your business objectives.

The result of epic shifts from traditional cable to streaming television, the CTV ecosystem is experiencing compounded fragmentation, making it challenging for marketers to leverage in the most effective way for both activation and measurement. Heralded as the hot new household level device for highly engaged viewers, CTV brings massive opportunities for brands to move users down the funnel and incorporate CTV into their attribution modeling post-campaign. Leveraging CTV IDs within a cross-device identity resolution strategy can yield big benefits if you know how to do it right. Check out our breakdown of today’s CTV landscape to help you better understand how and what you can leverage for activation and measurement in the streaming-verse today. CTV Ecosystems as identifiers (for illustrative purposes only) This is just a small peak at the players and complexities of CTV IDs available for marketers today, but it illustrates the need to understand what IDs can benefit your strategies and where you can use them. Addressability and attribution Not all CTV devices and IDs are addressable; or have ad slots for biddable inventory for advertisers. For example, Apple TV devices and Apple TV + are not ad supported, but could still appear within an identity graph for measurement purposes; helping understand customer behavior and habits, which can inform marketing strategies. Having a household to individual view that's as inclusive as possible can provide valuable insights. CTV identity strategy Whether or not CTV devices or apps are addressable for advertisers, they can bring immense value when leveraged as part of a holistic identity resolution strategy. As a household level device with user authentication it can provide marketers a top-down view; unlocking household:individual targeting opportunities and unification of IDs at both levels for frequency management and customer journey mapping Get started with us Tapad, part of Experian, offers CTV ID onboarding and extension to our CTV ID Universe as a part of The Tapad Graph suite of products.
