When an omnichannel campaign hits just right, it feels a little like magic. The customer browses a pair of boots on their phone in the morning, spots an ad for them on Instagram over lunch, and gets a text with a store discount as they’re walking past your shop downtown.
To the customer, it feels like you’re reading their mind. But really, it’s just interconnected data working behind the scenes. Most marketers already have access to the information they need to pull this off. The problem is that it’s sitting trapped in separate silos.
To make omnichannel work for your bottom line, you need to bring those data streams together. Here’s a look at the exact data stack driving those hyper-relevant moments and the steps to connect it all into a clear view of each customer.
Why data is the foundation of omnichannel marketing
Customer data fuels omnichannel marketing by telling you who your customers are, what they’ve done, and what they’re likely to do next. Every customer interaction, from opening an email to making a purchase, creates new data you can use to personalize future experiences.
For example, if a customer adds an item to their cart but doesn’t check out, that action can automatically trigger an abandoned cart email. If they open the email but still don’t complete their purchase, that opens the door for an SMS discount or retargeting ad on social media.
The more customers interact with your business, the more data you collect. Each interaction builds on the last, creating a richer customer profile. You can then use that data to deliver more relevant messages, better product recommendations, and automated journeys across every marketing channel.
Multichannel vs. omnichannel marketing data
While they sound similar, multichannel and omnichannel marketing handle customer data in completely different ways:
- Multichannel marketing focuses on expanding your reach across multiple platforms. However, each channel operates independently, managing its own customer info in a vacuum.
- Omnichannel marketing connects all your platforms together. Data flows freely between tools, creating a single, continuous conversation no matter where the customer finds your brand.
When you look at them side by side, it becomes obvious fast. Multichannel is about showing up everywhere, while omnichannel allows you to create connected customer experiences.
Benefits of connecting customer data across channels
The benefits of omnichannel marketing show up fast once you get all your data working together. Instead of treating every interaction as a separate event, you can create connected experiences that improve the customer experience, strengthen loyalty, and drive better campaign results.
Create a seamless customer experience
Connecting your data creates a smooth, interconnected experience through online and offline channels. For example, Sephora brings its iconic in-store experience into the digital realm with augmented reality. Shoppers can try on their products virtually at home, with their saved shades syncing directly to their profile for an effortless transition from screen to store.
Build stronger customer relationships
Deep personalization is the key to building customer loyalty. When you use connected customer data to deliver relevant messages and offers, it’s often easier to exceed customer expectations and keep people engaged. According to McKinsey’s 2025 research, 65% of customers say personalized promotions greatly influence their choice to buy. This means personalized experiences can help customers choose your brand more often and keep coming back.
Improve marketing campaign performance
Unifying your customer data allows various channels to support each other and guide buyers naturally toward a sale. In fact, 2024 research by Wisernotify shows that using at least 3 channels in a campaign can increase purchase rates by 287% compared with single-channel marketing efforts. So, it just makes sense to build an omnichannel marketing strategy, learn to connect your data, and let every channel work together.
4 data types every omnichannel strategy needs
An omnichannel approach is only as good as the data behind it. To meet customer needs and appear at the right moment, you need 4 types of data working together. Here’s a quick breakdown of each.
Identity data
Identity data connects every piece of data to a real human. It’s what turns a random click into “Sam clicked.” Within this category, you’ll find all the basic information that tells you who your customer is, such as:
- Name
- Location
- Birthday
- Contact info
- Customer ID
This data creates the foundation for unified, cross-device customer profiles. Creating the identity layer ensures every other piece of data you collect has something to attach to.
Customer behavior data
Customer behavior data tracks real-time interactions across your owned touchpoints. It reflects what users do on their own as they browse your online store, website, or mobile app, such as:
- Web pages viewed
- Products clicked
- Videos watched
- Searches run
- Carts abandoned
Every click, scroll, and search becomes a signal you can act on. With this data, you respond to what your customer wants in the moment, not what they told you months ago.
Transactional data
Transactional data is a living record of what your customer has bought. This category includes data like:
- Product preferences
- Purchase amounts
- Average order value
- Return history
- Order dates
Transactional data is your most reliable source of truth. Behavior data tells you what your customer might want. But transactional data tells you what they are actually willing to pay for.
Customer engagement data
Engagement data captures how people interact with your brand across all your customer touchpoints, including:
- Email opens and clicks
- SMS opens and replies
- Ad views and clicks
- Social likes and comments
- Push notification taps
If behavior data is what your customer does on their own, engagement data is how they react to your outreach. Together, they tell you what to say and where to say it.
Key sources of online and offline customer data
Many marketers find personalization difficult because they don’t know where to source the right data, and they don’t have a good way to link it all together. The fact is you need to consolidate data from multiple online and offline touchpoints to create a complete customer view.
That’s easier said than done, especially as businesses shift toward privacy-first marketing and rely more heavily on zero- and first-party data. But it’s doable, if you know which types of data to use and where to find them.
Zero-party data
Zero-party data comes directly from your customer, shared willingly and on purpose. It’s the info they hand over when they interact with a customer preference center, take a quiz or survey, or tell you what they want through social media interactions. This is the most reliable data you’ll ever have because the customer is literally telling you what they want.
First-party data
First-party data is information you collect directly from your customers as they interact with your brand. It builds accurate customer profiles by pulling things together like browsing behavior, purchase history, and marketing engagement. Your brand likely already has a lot of this data, though it might be scattered across different tools.
Second-party data
Second- party data is basically someone else’s first-party data, shared with you through a trusted partnership. For instance, your brand might team up with an app or content partner to share engagement data on shared audiences, like mobile app usage or activity across digital channels. Both sides walk away with a fuller picture of their customers.
Third-party data
Third-party data comes from outside providers who collect information from various marketing channels and public sources, then sell or share it with brands. This might include ad networks, data brokers, and demographic databases. It used to be the go-to for reaching new audiences, but privacy changes have made it less reliable and a lot harder to use.
Tools for collecting and managing omnichannel data
Knowing what data to collect is only half the equation. The other half is having the right tools connected to each other. That’s what turns scattered data from your digital channels and brick-and-mortar store into a unified customer view. Let’s explore the tools you can use.
Customer data platform (CDP)
A CDP is the central hub of your omnichannel data. It handles the heavy lifting of data integration by pulling customer information from every tool you use, like your website, marketing platform, and point-of-sale system. Then, it builds a unified profile for each customer, making it possible to recognize people across channels, including multiple device owners who switch between phones, tablets, and computers.
Customer relationship management (CRM) system
A CRM system is where your customer relationships live. It stores the identity and history side of your data, including contact info, past purchases, support conversations, sales notes, and account details. Sales, Marketing, and Customer Service teams can access the shared customer records, helping everyone work from the same information through the buyer’s journey.
All-in-one marketing automation platform
An all-in-one marketing automation platform pulls data in from various places and uses it to build campaigns across email, SMS, social media channels, and more. On many platforms, you can even build automated workflows targeting different customer segments created by predictive analytics. That way, you can deliver personalized experiences at scale and spend more time on strategy rather than letting execution consume your day.
Social media tools
Social platforms are goldmines of engagement data, from likes, comments, and shares to direct messages. A social media management tool brings all that data together into a single place. Add social listening tools to go a step further by tracking brand recognition data, industry conversations, and brand sentiment across the wider social web.
Digital ad platforms
Digital ad platforms like Meta, TikTok, and LinkedIn constantly generate valuable data, including impressions, clicks, conversions, and audience behavior. Connecting this information with your other customer data helps you understand which campaigns drive meaningful results.
Ecommerce platform
Your ecommerce platform is where the real buying signals live, such as product views, cart activity, and order history. When plugged into the rest of your stack, every purchase helps drive what happens next, whether it’s a smarter recommendation, a better follow-up email, or a well-timed loyalty perk.
Website analytics
Google Analytics and other website analytics tools show you exactly how visitors move through your site. You get to see the pages they view, how long they stay, and where they drop off. This is how you catch things like a product page with tons of traffic but no clicks or a checkout flow losing people at step 3.
Point-of-sale (POS) system
Your POS system connects physical transactions to your digital customer profiles. When someone buys in-store and scans a loyalty card or hands over their email, your POS ties that purchase back to their profile. It can also synchronize operational data, including inventory, pricing, and fulfillment, helping online and in-store experiences stay consistent.
Customer support tools
Customer support tools capture the moments when things go wrong or when a customer just needs a hand. Within these tools, every support ticket, chat conversation, and returned product generates valuable data. Connected to the rest of your stack, it helps you fix recurring issues and gives your Support team the context to solve problems faster.
How to connect customer data across multiple channels
Connecting your customer data is a process. But the good news is that it breaks down into 3 clear steps. Here’s how to get your data working across every channel.
Step #1: Choose your data hub
Every omnichannel marketing strategy needs a home base. You can choose either a CDP or an all-in-one marketing platform. A CDP pulls in data to build unified customer profiles, but you still use your other tools to run the campaigns. If you want to simplify your stack, an all-in-one marketing platform bundles your data and marketing channels together, so everything runs from the same system.
Step #2: Connect your marketing tools
Once you’ve picked your hub, it’s time to connect your marketing tools. The setup process depends on your data hub. With an all-in-one platform, many of your core marketing channels are already built in, leaving only third-party tools to connect. A CDP acts as the data layer, so you’ll also connect all the platforms that execute your omnichannel marketing campaigns. In most cases, native integrations make setup quick and easy.
Step #3: Confirm data syncs in real time
Once your tools are connected, run a quick test to confirm the data flows between them instantly. Simply update a test customer’s profile in a single tool and check if the change hits your central data hub within a few seconds. If there’s a delay, your platform might be defaulted to batch or scheduled syncs. In that case, you’ll want to switch that setting to real time to avoid delayed messaging.
Omnichannel journeys powered by customer data
With your data flowing freely across channels, you’re ready to start triggering personalized journeys. To help you get started, here are 7 classic omnichannel customer journeys powered by real-time data.
Welcome series
A welcome series sets the tone for new subscribers. When someone signs up online or in-store, your platform greets them across email or SMS in 3 parts. First, send a friendly welcome, then a quick intro to your brand, and finally a nudge to shop, complete with a new customer promo code.
Abandoned cart
An abandoned cart journey triggers when a logged-in user leaves items in their digital cart. A quick email reminder goes out, followed by a mobile notification or targeted social ad if they don’t convert right away.
Browse abandonment
A browse abandonment journey reaches shoppers who spent time looking at specific product categories but never added anything to their cart. Using multiple channels, you can follow up with tailored recommendations or helpful buying guides related to the exact items they viewed.
Buy online, pick up in-store (BOPIS)
BOPIS bridges your digital experience with physical operations. A great example of this is Starbucks, which seamlessly integrates its mobile app with in-store operations for effortless ordering, automated pickup alerts, and instant loyalty credits.
Post-purchase journey
A post-purchase journey helps you coordinate your pre- and post-purchase messaging, so customers never get ads for items they just bought. Instead, it triggers order tracking updates, product care tips, and timely cross-sell suggestions.
Customer winback
A customer winback campaign re-engages quiet customers before they churn. By tracking purchase frequency and engagement, your system automatically detects when a customer goes dark and reaches out on their preferred channels with a special incentive.
Loyalty program
A loyalty program keeps top customers engaged by syncing rewards across every touchpoint. For instance, Walgreens combines its loyalty program with digital tools, allowing shoppers to clip digital coupons, track rewards in the app, and redeem their savings seamlessly at the register.
Gauge your success with omnichannel data analytics
Once your omnichannel marketing campaigns are running, regularly review your key performance indicators (KPIs) to see what’s working. Depending on your tech stack, you may need to check reports on several platforms or view everything from a single dashboard in an all-in-one marketing platform.
Either way, keep a close eye on these KPIs:
- Cross-channel attribution: Reveals the full mix of touchpoints behind every conversion so no channel gets too much (or too little) credit
- Engagement rate across different channels: Measures how customers interact with your brand across every channel, so you can spot where you’re truly connecting
- Conversion rate by journey: Tracks conversion across the entire customer journey, so that you can compare your welcome series to your winback flow and everything in between
- Customer lifetime value: Measures the long-term value of each customer so you can see if your omnichannel efforts are building real relationships
- Repeat purchase rate: Shows how often customers return for another purchase, giving you a quick read on loyalty
Make every touchpoint count with connected data
Omnichannel marketing is a promise: No matter where a customer runs into your brand, the experience will feel seamless and rewarding. Connected data is what keeps that promise. It gives every channel a shared memory, so your customer never has to repeat themselves, start over, or feel like a stranger. So don’t wait another moment to connect your data and start delivering the seamless experiences your customers expect.
