Enterprise Marketing Platform for Omnichannel B2C Brands

There’s a hidden cost to treating your customers’ most-used channels as separate tools: the marketing coordination tax.

The marketing coordination tax amounts to every hour your team spends syncing data, reconciling attribution across vendor dashboards, and re-segmenting audiences in multiple tools instead of running marketing activations.

60% of marketing teams have 6–15 different tools in their tech stacks, according to Klaviyo’s 2025 State of B2C Marketing Report . Think about it: if your team spends an average of 5 hours a week on cross-tool coordination and martech administration, that's 260 hours a year—over 6 full work weeks—you’re spending on upkeep instead of strategy.

The No. 2 priority marketers have for their tech stack in 2026 is upgrading their ecommerce or customer experience infrastructure, according to Klaviyo’s 2026 B2C marketer research. When tech sprawl and channel fragmentation are making your customer experience more frustrating, an enterprise marketing platform with a built-in customer data platform (CDP) is a long-term fix that will help you meet your customers’ expectations.

The problems with disjointed enterprise marketing tech stacks

Most enterprise marketing stacks weren't designed. They accumulated.

As consumers shifted how and where they shopped, marketers and their supporting tech followed. First an email service provider, and then a text messaging point solution, a vendor supporting push notifications, followed by WhatsApp.

It’s not that these purchases weren’t intentional. Each tool made sense in isolation. The problem is the seams between them: separate data models, contact lists, attribution logic, and reporting.

As you scale, these seams start to show up in:

• Poor customer experience: 82% of global consumers shop across more than one channel, according to Klaviyo’s 2026 future of consumer marketing research. When each channel lives in a different system, has a different vendor, and is running on a different data model, it shows up in the form of redundant messaging, poor personalization, and inconsistent experiences across channels.
• Developer-dependent marketing: If your marketing team has to file a ticket every time they want a new segment, the experience isn’t modern even if the platform is. Most enterprise tech stack set-ups require external data syncs, a standalone CDP, and a team of dedicated solutions engineers to build segments and bring in behavior and preference data before you can personalize a single message. This leaves your marketing in the hands of developers rather than marketers.
• Wasted budget: If you have multiple dashboards reporting separately on your varied marketing metrics, it means you’re almost certainly double- or triple-counting conversions. These independent reports give you no sense for which channels are actually delivering impact to consumers. Without cross-channel attribution informing your omnichannel marketing, your reports lack context and aren’t accurate.

Omnichannel marketing relies on shared data

True omnichannel marketing requires a data model that can grow with you while supporting new and changing channels.

When you orchestrate all of your marketing channels from the same enterprise marketing platform with a built-in CDP, everyone encounters a more seamless experience: customers can shop exactly how they want without feeling friction or receiving disjointed or redundant messaging, and team members reference one data model to track and improve marketing efforts.

Klaviyo is the autonomous B2C CRM with a built-in CDP , which unifies email, text messaging, WhatsApp, mobile push, and social media alongside customer service and agentic AI in the same system that houses and analyzes your data.

Here’s how Klaviyo solves the problems created by a disjointed tech stack:

Sharper personalization for a better customer experience

With Klaviyo, segments, flows, and personalization span every channel. All of your messaging, across marketing and customer service, draws on the same unified customer profiles , in real time. That means every message reflects what you’ve learned about each customer anywhere they interact with you, such as:

• Predictive analytics like predicted customer lifecycle value, churn risk, and anticipated next order dates to support personalized, proactive marketing
• Channel affinity , which tells you which channel a customer is most likely to engage on
• Personalized product recommendations based on order history, behavior, and customer preferences
• Personalized send times based on exactly when each subscriber is most likely to open, click, and convert

Intimates brand Thirdlove moved to Klaviyo to consolidate their text message and email marketing in one place. Now, they can build personalized cross-channel flows and campaigns more easily. Their abandoned cart flow, for example, uses channel affinity to make sure multi-channel subscribers get the message where they’re most likely to engage. In Q2 2025, Thirdlove saw substantial QoQ growth in revenue from flows .

Marketer-led marketing

Klaviyo lets marketers work autonomously, from building flows to launching campaigns to tracking results. With no-code tools like customizable templates , a flexible web form builder , and live dashboards, you can make decisions without waiting on developers or IT.

That’s one of the reasons grooming and personal care brand Dollar Shave Club switched to Klaviyo. Before, pulling customer data for segmentation could take a month or more, and their lifecycle team used to work with 4 developers. Now, they work with one at most. Since switching to Klaviyo, they’ve seen over a 60% reduction in campaign set-up time .

Cross-channel, customizable attribution

While last-click or first-touch attribution models are popular, they ignore the influence of the majority of customer touches. With cross-channel attribution, you can see the complete customer journey, better gauge where your messaging lands, and iterate in real time to land even more conversions.

That’s especially important for enterprise brands. Here’s how Klaviyo helps you get attribution right :

• An omnichannel, linear multi-touch attribution model that helps you better understand each step of the complex modern customer journey, from discovery to purchase
• Customizable attribution windows depending on your unique business needs
• The flexibility to adjust settings retroactively, select which success metrics matter to you, and exclude bot clicks and opens

What to ask any enterprise marketing vendor before purchase

If you're ready to switch to an omnichannel marketing platform, ask the following questions before committing to one:

1. What channels are included (email, text messaging, WhatsApp, push notifications)?
2. Can my marketing team build segments without engineering?
3. Do all channels share a single customer record?
4. Is cross-channel attribution native or stitched together?
5. What’s the real implementation timeline?
6. Is segmentation logic real-time or scheduled?
7. What’s the TCO including services?

What you’re looking for is a single platform backed by powerful AI that can plan and run personalized campaigns and flows across every channel your customers touch and catch every attribution.

With Klaviyo's powerful enterprise omnichannel marketing capabilities, you can avoid the coordination tax, know your customers better, and make every interaction more meaningful at scale.
