The average marketing technology landscape now lists over 14,000 products. The average marketing team uses between 15 and 30 tools, depending on size and sector. And in the majority of organisations, the stack was never designed. It grew. A CRM was added in year one. An email platform in year two. A social scheduling tool when the social team was hired. A project management system when campaigns started running over deadline. An analytics platform when the board started asking for better reporting. Each addition made sense at the time. The cumulative result is a stack that is expensive, partially integrated, and largely underused.
Building a marketing tech stack that actually serves the team requires starting from a different place — not from the available tools, but from the activities the team needs to perform and the data the team needs to access to make good decisions.
Start with jobs to be done, not tools available
Before evaluating any marketing technology, define the jobs your team needs to do. Not in technology terms — "we need an email platform" — but in process terms: "we need to send personalised nurture sequences to segmented prospect lists, track email engagement, and connect that engagement data to our CRM so sales can prioritise follow-up." That description tells you what any email tool must do to earn its place in the stack. It also tells you what the tool must integrate with, which is where most technology decisions go wrong.
Integration is the most underweighted decision factor
Most technology buying decisions focus on features — what the tool can do in isolation. The more consequential question is what the tool can do in connection with the rest of the stack. A tool that does its specific job well but does not integrate reliably with your CRM, your analytics platform, or your content management system will create data silos that cost more in manual reconciliation than the tool saves in automation. The marketing teams with the most functional stacks have typically sacrificed some individual feature richness for significantly better integration across the set.
A tool that does not integrate reliably with your stack creates data silos that cost more to manage than the tool saves in automation.
The audit that reveals what you actually have
Before any new tool acquisition, run a technology audit that answers five questions about every tool currently in the stack. First, what specific problem was this tool purchased to solve, and is it solving it? Second, how many people on the team use it at least weekly? Third, does it integrate reliably with the tools it was supposed to connect to? Fourth, what does it cost in total — licence, implementation, and maintenance — and is that cost justified by what it delivers? Fifth, if this tool were unavailable tomorrow, how long would it take to replace it and what would break in the meantime?
This audit consistently produces the same revelation: between 30 and 50% of tools in the average stack are underused, poorly integrated, or solving a problem that has since been solved by another tool already in the stack. Removing them is not a compromise. It is a simplification that makes the remaining tools more powerful by concentrating usage and improving the quality of integration between the tools that remain.
The data layer is the foundation
The single most important infrastructure decision in marketing technology is not the tools at the top of the stack — the execution layers, the creative tools, the content management systems. It is the data layer at the foundation: where customer and prospect data lives, how it is structured, how it is maintained, and how it flows between the tools that need to access it. Marketing teams with a clean, well-maintained data layer get dramatically more value from every tool in their stack. Teams without one find that every new tool they add creates a new version of the same data quality problem.
How to make better technology decisions going forward
The most effective change a marketing team can make to its technology procurement process is introducing a mandatory integration test before any new tool is approved. Before purchase, the team must demonstrate that the tool can exchange data reliably with the two or three systems it must connect to. If it cannot do so out of the box and the integration cost is above a defined threshold, the tool is not approved regardless of its standalone feature set.
The second change is establishing a technology review cycle — at minimum annual, ideally quarterly — at which each tool in the stack is evaluated against current usage and current cost. Tools that are not meeting a usage threshold or delivering clear value are decommissioned. This prevents the gradual accumulation that turns a functional stack into an expensive collection of partially used platforms.
The goal is not to have the most advanced marketing stack. It is to have the smallest stack that reliably does what your team needs to do — and gets out of the way when they need to do it quickly.
