Omnichannel marketing: The path to more connected campaigns

Marketers aren’t thinking in channels anymore: they’re thinking in audiences.

As consumer media habits have scattered across devices, platforms and formats, brands have shifted their focus from managing one channel at a time to delivering a connected experience. That’s the core of omnichannel marketing: meeting people where they are and making each touchpoint feel like part of a larger narrative.

However, most brands still encounter the same roadblocks: siloed data, fragmented planning and tools that don’t integrate. And while the industry talks a great deal about omnichannel marketing, few are actually doing it well. The brands that figure it out won’t just reach more people; they’ll improve brand perception while improving the customer journey, achieving better outcomes, and optimizing their media spend more efficiently.

Why omnichannel is no longer optional

Omnichannel marketing has long been a goal, but recent shifts in media and technology now make it a necessity. According to Forrester, 21% of global B2C business and tech professionals identified enhancing omnichannel or cross-channel customer experiences as a top priority for their organization today.

Connected TV (CTV) and commerce media networks are emerging as dominant channels, necessitating the coordination of messaging across an expanding ecosystem of streaming, programmatic display, and commerce-driven environments in addition to the multitude of other addressable (and non-addressable) channels. Fortunately, identity solutions continue to evolve, enabling marketers to maintain audience addressability in digital channels even as traditional signals decline and privacy regulations intensify.

Consumers expect this kind of cohesion. They don’t see “channels” – they just see a brand. A member of your loyalty program might browse a product online, see the exact item later on their socials, and then receive an email offer. If those messages feel disconnected or out of sync, this will not be a good customer experience, and a brand risks wasting impressions and losing conversions.

Omnichannel isn’t about showing up in more places. It’s about showing up with a consistent message.

The opportunities inherent in true omnichannel execution

Despite the industry’s movement toward omnichannel marketing strategies, there are a few untapped opportunities brands would benefit from pursuing.

Break down planning silos to optimize performance

Many marketers still plan and measure media in silos: programmatic display, CTV, commerce media, search, social, email, SMS, and each might have their own budgets, strategies, and KPIs. This disjointed approach leads to inconsistent messaging, inefficient spend, and overexposure or underexposure to key audiences.

The opportunity? Shift toward integrated media planning and measurement. By aligning teams and KPIs across channels, marketers can optimize frequency, coordinate creative sequencing, and better attribute business outcomes. Breaking down internal silos improves the customer experience and drives more effective performance. With two-thirds of North American CMOs naming siloed data as their biggest obstacle, those who solve it stand to gain a clear advantage.

Encourage interoperability to activate audiences consistently

Omnichannel success depends on defining an audience once and reaching them everywhere. But in today’s ecosystem, where walled gardens control inventory and many tools remain disjointed, this is easier said than done. Just under a third of marketers say the tools they use don’t work well together.

The opportunity? Invest in interoperable systems that give you control over your data and privacy-safe solutions like clean rooms or universal IDs that enable consistent audience activation across platforms.

Advocate for a unified identity framework

Audience data remains fragmented: commerce media networks control shopper data, TV platforms hold viewership data, and walled gardens provide limited data transparency and determine which data they will share, making it difficult to recognize, reach, and follow the customer journey across digital touchpoints. Without a unified view, campaigns remain disconnected and cross-channel attribution is difficult.

The opportunity? Advocate for a centralized, privacy-conscious identity framework that bridges fragmented data sources. This would allow marketers to recognize consumers across platforms and deliver cohesive messaging.

Marketers need solutions that enable connected audience activation while respecting privacy requirements and platform-specific constraints. Without this, omnichannel remains an aspiration rather than a reality.

Data and identity: The tools you need in your toolkit to make omnichannel work

Implementing omnichannel right starts with establishing identity. Brands need a foundation that lets them connect the dots: across data, platforms and channels. Here’s how:

Build a unified identity foundation

“A single view of the customer is the foundation of a successful omnichannel program,” says Forrester in a December 2023 report on omnichannel. This begins by connecting disparate data sources, including persistent offline information, such as addresses, emails, names, and phone numbers, with digital signals, in a privacy compliant way. And this, in turn, creates a strong identity foundation. Solutions that integrate hashed email addresses (HEMs), mobile ad IDs (MAIDs), IP addresses, CTV IDs, and universal IDs enable brands to resolve customer identities across different platforms, ensuring that campaigns remain addressable as users transition between channels.

Activate audiences everywhere, without the hassle

Brands should be able to define an audience once and activate it across all addressable channels without unnecessary complexity. Interoperability between demand-side platforms (DSPs), supply-side platforms (SSPs), clean rooms, and private marketplaces (PMPs) ensures that high-quality audiences are matched with premium inventory in a targeted, transparent, and efficient manner. This connectivity helps maintain consistent audience targeting—even as consumers engage in different environments. By working with a partner that seamlessly integrates with major platforms, marketers ensure that data quality and identity resolution remain intact throughout campaigns, avoiding data loss that occurs when data is transferred between different, disparate platforms.

Measure across channels, and the customer journey

Effective omnichannel marketing isn’t just about reaching audiences—it’s about understanding how different touchpoints contribute to conversions. Advanced attribution models, incrementality testing, and cross-platform frequency management enable brands to use consistent identity across campaign planning, activation and measurement so they connect ad exposures to real-world outcomes. Achieving this requires a strong identity resolution partner—one that can unify audience data across environments and power accurate, privacy-compliant measurement at scale.

The future of omnichannel marketing

Omnichannel is becoming the baseline expectation for modern marketing. The brands that figure out how to connect the dots across the increasingly disparate media landscape will drive better performance and build stronger customer relationships.

By working with a partner that can offer you an end-to-end data and identity solution focused on consumers, not channels, you can better understand your best customers (and your next customers), reach them across channels, and measure cross-channel campaigns more effectively, making true omnichannel execution more achievable.
