How do you use an identity graph for omnichannel marketing?
An identity graph powers omnichannel marketing by giving your brand a unified, persistent view of each customer across every channel and device they interact with. Instead of treating the same person as a different user on mobile, desktop, and in-store, an identity graph connects those touchpoints into a single resolved profile. The sections below unpack how this works in practice, how it compares to other tools, and where it fits in your marketing stack.
What can an identity graph actually do across channels?
An identity graph enables marketers to recognize the same individual across every channel, device, and interaction, whether they are browsing anonymously, clicking an email, or walking into a store. By linking identifiers like email addresses, device IDs, and cookies to a single resolved profile, it makes consistent, coordinated messaging possible at scale.
In practical terms, this means a customer who browses a product on their phone in the morning can receive a relevant follow-up display ad on their laptop that afternoon and a personalized email that evening, all without the experience feeling disjointed. The identity graph is what makes those connections invisible to the customer but powerful for the marketer.
The most meaningful capabilities identity graph marketing unlocks include:
- Suppressing ads to existing customers to avoid wasted spend
- Sequencing messaging across channels based on where someone is in the buyer journey
- Measuring true cross-channel attribution rather than crediting the last touchpoint
- Personalizing experiences for anonymous visitors by resolving their identity in real time
How does an identity graph connect online and offline customer data?
An identity graph connects online and offline customer data by matching shared identifiers, such as an email address captured in-store or a loyalty ID tied to a digital account, to the same underlying person. This matching process bridges the gap between what a customer does in the physical world and how they behave across digital channels.
Offline data sources, including point-of-sale records, loyalty program sign-ups, and event registrations, often contain strong identifiers like full names, postal addresses, and phone numbers. Online data sources contribute device signals, browsing behavior, and authenticated logins. An identity graph ingests both, resolves the overlapping identifiers, and produces a single customer record that reflects the full relationship.
This matters most when a significant portion of your customers interact with your brand in both environments. Without a connected identity layer, a retailer might send a promotional email for a product the customer already purchased in-store, or fail to recognize a high-value loyalty member when they arrive on the website. The identity graph eliminates those blind spots by keeping the profile current across every data source feeding into it.
What’s the difference between an identity graph and a CDP?
An identity graph and a customer data platform (CDP) serve different but complementary functions. A CDP is a system that collects, stores, and organizes customer data from multiple sources into unified profiles. An identity graph is the resolution layer that determines which data points belong to the same real person, making those unified profiles accurate and persistent over time.
Think of it this way: a CDP is where customer data lives, and an identity graph is what makes that data trustworthy. A CDP without strong identity resolution can create duplicate profiles, merge the wrong records, or lose track of a customer when they switch devices. An identity graph solves that problem by continuously matching and resolving identifiers, regardless of where they originate.
Many organizations use both together. The identity graph feeds resolved, de-duplicated profiles into the CDP, which then uses those profiles to power segmentation, automation, and analytics. Neither replaces the other. The key distinction is that an identity graph is purpose-built for resolution and matching, while a CDP is purpose-built for activation and storage.
