Stack Struggles: The Totally Tangible Benefits Of A Unified — And AI-Powered — Marketing Platform

Marketing Manager has long prided itself on being an all-in-one CRM and marketing automation platform. And with an ever-growing number of AI tools built right in, that kind of unified platform is arguably all the technology a marketer could need to thrive in 2025.

But don’t take our word for it. 

Marketers in a new report say the top three technology investments their companies are prioritizing this year are AI tools (47%), CRM platforms (44%), and marketing automation platforms (39%), all tools that Klaviyo says “hold significant potential to personalize customer experiences, automate processes, and boost engagement.”

“Most marketers are working with bloated tech stacks that limit their view of the customer and diminish ROI,” says Klaviyo’s 2025 State of B2C Marketing report, which found that 60% of marketing teams are using between 6 and 15 marketing tools.

In addition, 14% blame data silos as their biggest barrier to comprehensive, real-time views of their customers. Those brands with aligned and integrated silos, on the other hand, saw “major gains in performance, satisfaction, and profitability,” including being 156% more likely to exceed their marketing goals.

“Marketers using Al are 46% more likely to exceed their goals in 2025 than those not using Al,” the report says. “Brands can deliver relevant experiences at scale, optimize performance in real-time, and make smarter decisions across the funnel.”
