What Is a Martech Stack?
A martech stack (marketing technology stack) is the set of software tools an organization uses to plan, execute, measure, and improve its marketing — from the CMS and email platform through to analytics, CRM, and advertising tools. The word "stack" implies the tools work in layers that build on each other. In practice, many stacks are less a stack than a pile: tools acquired one campaign at a time, each holding its own copy of customer data.
The average mid-market company runs dozens of marketing tools, and the industry's tool landscape has grown past 15,000 products. The strategic question has shifted from "which tool should we add?" to "which tools should we remove — and what should sit at the center?"
The Layers of a Martech Stack
Most stacks resolve into five functional layers:
- Experience and content — the CMS or digital experience platform that runs your website, landing pages, and content operations.
- Data and identity — the CRM and customer data layer that stores who your customers are and what they've done.
- Engagement and delivery — email, marketing automation, social, and advertising platforms that carry messages to people.
- Measurement — marketing analytics, attribution, and reporting tools.
- Integration — the connective tissue: native integrations, webhooks, APIs, and iPaaS tools that move data between everything else.
The Real Cost of Stack Sprawl
- Data fragmentation. When six tools each hold a version of the customer, no report agrees with another and personalization runs on stale data.
- Integration tax. Every added tool multiplies connections to maintain. Integration work quietly becomes a permanent engineering cost.
- License overlap. Sprawling stacks routinely pay for three tools that share one job — audits regularly find 20–30% of martech spend going to redundant or unused seats.
- Slower campaigns. Launching anything requires touching five systems, so the stack that promised agility becomes the bottleneck.
How Core dna Works With Your Martech Stack
Core dna's approach to martech is consolidation at the core, openness at the edges. The platform combines the experience, content, commerce, and automation layers in one system — a digital experience platform — so the jobs that most commonly fragment (CMS, landing pages, forms, personalization, workflows) run on one customer record and one content repository instead of four subscriptions.
For everything that rightly lives outside the core — your CRM, ERP, email platform, analytics — Core dna ships native integrations plus webhooks and APIs, so data flows both ways without custom middleware. The result is a smaller stack with fewer seams: fewer licenses to reconcile, fewer copies of the customer, and campaigns that launch from one place.
