Is Identity Resolution the Future of Marketing?

Identity resolution has long been key to understanding the customer journey, traditionally enabling enterprise businesses to consolidate the many, many data points they have into a cohesive customer profile. 

However, with recent shifts in the digital space, notably the phasing out of third-party cookies and increased privacy regulations, marketers and businesses of all sizes are taking notice of this technology. 

In fact, a staggering 87% of marketers agree that identity resolution is key to future-proofing their campaigns! 

As tools like Google Analytics evolve and restrict access to once readily available data, marketers are leaning into identity resolution to navigate attribution.

It makes us wonder, “Is identity resolution the future of marketing?”.

The answer. It certainly feels like it.

Let’s dig a little deeper and find out just why identity resolution is so important to the marketing landscape and this new age where data is sacred and attribution feels impossible.

Understanding Identity Resolution

At its heart, identity resolution seems pretty simple. But there is a lot to it and understanding what it is and its role in business and marketing is important.

What is Identity Resolution?

Identity resolution is a data processing technique used by marketers to aggregate and analyze interactions and touchpoints from various sources to build a singular, cohesive identity of a consumer. 

This process involves matching customer data points, such as email addresses, social media profiles, and device identifiers, across different channels and platforms. 

By doing so, it allows businesses to understand and track an individual’s journey with their brand, enabling personalized marketing efforts and a more comprehensive understanding of consumer behavior.

Ok…that’s the boring definition. 

Identity resolution basically takes all the things you know about your customers and prospects and puts them into one place (think name, email, address, business role, family connections, hobbies, etc).

For marketers, this is GOLD!

What are the Two Types of Identity Resolution?

It’s important to note there are two types of identity resolution: deterministic and probabilistic.

Deterministic matching operates on the principle of exactness, linking customer records by pinpointing exact matches among identifiers such as email addresses, phone numbers, or usernames. This method is best when there’s a wealth of first-party data at one’s disposal.

On the flip side, probabilistic matching takes a more nuanced approach, estimating the probability that different identifiers—think IP addresses, device types, browsers, or operating systems—belong to the same customer. While this approach might not offer the certainty of deterministic matching, it opens doors when first-party data is scarce or when expanding reach is the goal.

While no one likes what essentially feels like “guesswork”, sometimes probabilistic is the only way to go.

What Technologies Are Used in Identity Resolution?

There are a lot of technologies that go into identity resolution. After all, to get a true picture of an individual, you need to track them both online and in real life. 

Here’s a breakdown of how to think about it:

​​The Collectors: Data Management Platforms (DMPs)

DMPs collect and organize data from a variety of sources, enabling marketers to better understand and segment their audiences. They are essential for targeting and personalization efforts in marketing campaigns.

The Organizers: Customer Relationship Management (CRM) Systems

CRMs store and manage customer interactions across different channels, providing a unified view of the customer journey. This helps businesses tailor their communications and improve customer relationships.

The Brainiacs: Artificial Intelligence (AI) and Machine Learning (ML)

AI and ML technologies analyze data to identify patterns and predict future behaviors. They enhance identity resolution by improving the accuracy of matching customer data across various sources.

The Connectors: Identity Graphs

Identity graphs compile data from multiple channels and devices to create comprehensive profiles of individual customers. They are key to understanding customer behavior and delivering consistent marketing messages.

The Protectors: Blockchain Technology

Blockchain offers a secure and transparent way to manage identity data. Its decentralized nature helps protect against fraud and ensures the integrity of customer information.

These technologies collectively empower marketers to achieve a holistic understanding of their customers, driving more effective and efficient marketing strategies.

The Benefits of Identity Resolution for Marketers

Over the past few years, marketers have seen more and more of their data disappear. 

In 2020, we saw iOS 14 wipe out ad audiences and in 2024, we are seeing cookies crumble to the wayside. 

Oh, and did I mention GA4? 

The result is an urgent need for a solution that gives us our data back and helps us make smarter marketing decisions. 

Let’s look at a few ways identity resolution benefits marketers.

1. Personalized Marketing at Scale

With identity resolution, marketers can move beyond broad segmentation and generic messaging to tailor their outreach with precision. 

This capability is only possible because of the rich, unified customer profiles that identity resolution provides – preferences, behaviors, interaction histories, and more. 

With this data, marketers can craft messages that speak directly to the needs and interests of each customer, enhancing engagement and fostering loyalty.

Additionally, the scale at which personalized marketing can be achieved with identity resolution is totally unprecedented. 

Automated technologies and sophisticated algorithms allow for the processing of huge amounts of data, ensuring that personalized experiences can be delivered to not just hundreds, but millions of customers simultaneously. 

This scalability ensures that businesses of all sizes can leverage the power of personalization to compete effectively in their markets.

2. Enhanced Targeting and Retargeting Campaigns

As we’ve discussed many times, one of the biggest victims of privacy changes is retargeting. 

Campaigns that used to perform unbelievably well now barely make a dent. Unless you have extremely targeted and segmented first-party lists, you might as well kiss retargeting success goodbye.

That’s where identity resolution comes in. It gives you the first-party data you need to retarget efficiently. 

That first-party data can be put directly into your retargeting campaigns, allowing you to reach the right people, with the right message, in the right place.

The real bonus is that by accurately identifying and understanding customers across devices and platforms, marketers can ensure that their advertising dollars are being spent on the most receptive audiences. 

3. Attribution and Customer Journey Mapping

Remember when Google Analytics would tell you which pages a user landed on, which pages they visited, and which channel they converted from?

That feels like a lifetime ago and I hate to tell you, it’s not getting any better. 


You guessed it – identity resolution!

Identity resolution gives us back some of the attribution and customer journey mapping data we used to have. 

If you are using the Website Visitor ID X-Ray pixel for example, you can see the pages each user visited, if they were sent an email, and if they made a purchase. Crazy right?!

By accurately linking each interaction to the same individual, we can map out the entire customer journey, from initial awareness through to conversion. 

This granular view allows marketers to attribute conversions and other key actions to the specific channels, campaigns, and messages that influenced them, providing invaluable insights into what works and what doesn’t.

Even better, understanding the customer journey at this level helps marketers to optimize their strategies in real time, reallocating resources to the most effective channels and touchpoints. 

The role of identity resolution in marketing cannot be overstated. By leveraging the comprehensive insights provided by identity resolution, marketers can deliver the right message, to the right person, at the right time, maximizing impact and driving sales.

Future Trends in Identity Resolution

Identity resolution may not be a new concept but it does feel like it’s starting to make waves in the marketing space.

Previously, CDPs and identity resolution platforms were only accessible to big companies with big budgets. 

Not anymore. 

Emerging trends and technologies, such as AI and blockchain, are making this technology more accessible and redefining how marketers understand and interact with their audiences. 

These advancements promise not only to enhance the accuracy and efficiency of marketing programs and reshape consumer experiences in exciting new ways. Let’s look at a couple trends impacting the future of identity resolution. 

The AI Revolution in Identity Resolution

AI is already taking identity resolution to new heights (hello….CUSTOMERS.AI). 

With its ability to process and analyze data at unprecedented scales, AI is improving the accuracy of matching algorithms, enabling more precise identification of individuals across devices and platforms. 

This leap in precision will allow for even more personalized marketing strategies, as businesses will be able to understand their customers’ needs and preferences in real time, responding with tailored messages that hit the mark every time.

Moreover, AI’s predictive capabilities are set to revolutionize customer journey mapping, forecasting future behaviors based on past interactions. 

Blockchain: Privacy and Security is a 100% privacy-compliant solution but we do understand people’s concerns when they hear about this groundbreaking technology.

As consumers become more aware of their digital footprint, the demand for transparent and secure data practices continues to rise.

Blockchain technology offers a promising solution to the growing concerns around privacy and data security in identity resolution. 

By creating a decentralized record of customer identities, blockchain can provide a secure framework that respects user privacy while still allowing for personalized marketing. 

This balance between personalization and privacy is the holy grail for marketers, and blockchain could be the key to achieving it.

Marketing Technology Integrations

The potential for identity resolution to integrate seamlessly with other marketing technologies is immense. 

The goal? A unified marketing ecosystem where every piece of customer data is leveraged to its fullest potential, delivering a cohesive and personalized customer experience across all touchpoints.

Such a connected ecosystem would not only streamline marketing operations but also provide deeper insights into customer behavior, enabling more strategic decision-making. 

As identity resolution becomes more intertwined with other marketing technologies, we can expect to see a more holistic approach to customer engagement, where every interaction is informed by a comprehensive understanding of the individual’s journey.
