Hindered Personalization: The Hidden Cost of Marketing Siloes

Why disconnected marketing tools make personalization nearly impossible—and what businesses can do to bridge the gap.

In our previous blog post, we explored the many ways fragmented marketing technology can harm businesses—from wasted budgets to inefficiencies and lost revenue opportunities. In this second installment of our series on marketing siloes, we’re taking a closer look at one of the most damaging impacts: Hindered Personalization.

Personalization is no longer optional. According to McKinsey’s Next in Personalization 2021 Report, companies that excel at personalization generate 40% more revenue than those that don’t (source). Meanwhile, 70% of consumers say they are likely to switch brands for a better personalized experience, as noted in FTI Consulting’s 2023 Online Retail Report (source).

Despite this, most businesses struggle to deliver effective personalization at scale. The reason? Marketing technology siloes prevent organizations from fully understanding, segmenting, and acting on customer data—resulting in generic, one-size-fits-all messaging that falls flat.

Why Siloed Tech Stands in the Way of Personalization

Effective personalization requires marketing teams to:

• Unify customer data across multiple channels (email, SMS, website interactions, purchase history).
• Segment customers dynamically based on behavior, intent, and demographics.
• Create tailored content variations for different audiences.
• Optimize message timing and delivery to reach customers at the right moment.
• Analyze and refine messaging strategies based on real-time feedback.

But in a fragmented marketing tech stack, each tool captures and stores customer data in isolation. Your email platform might track open rates, your SMS tool might monitor click-throughs, and your eCommerce system might log purchases—but these insights rarely talk to each other. The result? Personalization becomes an uphill battle, riddled with manual workarounds and inefficiencies.

Marketers often find themselves manually exporting and importing data, trying to stitch together customer profiles across disconnected platforms. Creating personalized messaging requires hand-built segments, custom rules, and constant intervention—making personalization slow, reactive, and error-prone.

How Marketers Try to Personalize Without a Unified System

For brands stuck in this fragmented reality, some strategies can help improve personalization—though they require significant effort:

1. Manually Centralizing Data – Using customer data platforms (CDPs) or spreadsheets to consolidate cross-channel insights.
2. Behavior-Based Automations – Setting up basic if-then workflows in email and SMS platforms to trigger messages based on user actions.
3. Static Segmentation – Creating predefined customer personas based on broad demographic or transactional data.
4. A/B Testing and Iteration – Running manual experiments to optimize subject lines, images, and CTAs over time.
5. First-Party Data Collection – Prioritizing owned data sources to build a clearer picture of customer behavior.

While these tactics offer incremental improvements, they don’t scale easily. Marketers still bear the burden of manually segmenting, personalizing, and optimizing their campaigns—a process that takes time, resources, and constant monitoring.

The Shift from Manual to AI-Powered Personalization

Instead of relying on manual segmentation and rule-based automations, modern AI-driven platforms are removing friction from personalization by:

• Automating Customer Segmentation – AI continuously refines dynamic segments based on real-time behavior and intent.
• Generating Personalized Content Variations – AI creates tailored messaging for different customer groups without manual intervention.
• Predicting the Best Timing for Engagement – AI analyzes customer behaviors to optimize when to send messages for the highest engagement.
• Unifying Customer Data Across Channels – AI-powered platforms break down siloes, enabling true cross-channel personalization.

This transition from rule-based marketing to AI-driven personalization is critical for brands that want to stay competitive. Yet, most existing marketing platforms still operate in siloes—forcing marketers to juggle multiple disconnected tools and leaving the promise of AI-powered personalization largely out of reach.
