What Is Composable Architecture and Why Should Marketers Care?

Ever felt trapped by your marketing technology stack? You're not alone. Marketers need flexibility, speed, and precision to deliver exceptional customer experiences. Have you heard of composable architecture — a modern solution to some of the biggest marketing challenges?

Published January 21, 2025

What Is Composable Architecture? 

Think of composable architecture as your ultimate marketing LEGO set. Instead of being stuck with a rigid, one-size-fits-all platform, you can pick and choose the best tools for each specific need. Want the most powerful analytics engine? Add it. Need a cutting-edge personalization tool? Plug it in. The magic lies in how these pieces work together seamlessly through APIs. 

But what makes it truly special? Here are MACH principles: 

  • Modular: Independent pieces that can be mixed, matched, and replaced without affecting the whole system. 
  • API-Driven: APIs act as the glue, ensuring smooth communication between tools. 
  • Cloud-Native: Designed to take advantage of the flexibility and scalability of the cloud. 
  • Vendor-Agnostic: Pick and choose the best tools for your needs without being tied to a single provider. 

 

Example: A retail company might use a headless CMS like Contentful for managing content, a CDP to unify customer data, and an AI-driven personalisation tool. These systems communicate via APIs to deliver personalised, consistent experiences on the website, mobile app, and in-store kiosks—without relying on one monolithic platform.

How Does Composable Architecture Address Marketing Challenges? 

Let's get practical. Imagine you're running a professional services firm. Your current setup includes: 

  • A CRM for client management 
  • An email marketing platform 
  • A content management system 
  • Analytics tools 

With traditional architecture, these systems might operate in silos. But with composable architecture? They work in perfect harmony. When clients interact with your website, their behaviour automatically updates their CRM profile, triggers personalised email campaigns and feeds into your analytics – all in real-time. 

 

1.Personalisation at Scale

Personalisation is a demand nowadays. But delivering real-time, tailored experiences across channels is no easy feat with traditional platforms. Composable architecture lets you integrate tools like a Customer Data Platform (CDP) with a headless Content Management System (CMS) to create hyper-personalised experiences. 

Example: For a law firm or consultancy, composable architecture could combine a CRM like Salesforce to track client interactions, a document automation tool like HotDocs to generate personalised legal documents, and a headless CMS like Contentful for client-facing portals. When clients log in, the system dynamically pulls personalised resources based on their case or contract status. 

 

2. Rapid Adaptability

New social platform? Industry shift? Composable systems let you pivot quickly by adding or swapping tools without overhauling your entire tech stack. 

Example: A professional services firm might want to quickly deploy a new knowledge-sharing platform for its internal teams. By integrating a cloud-based tool like SharePoint with Slack via APIs, they can launch the platform swiftly. If they decide to move to Teams or another collaboration tool later, the modular architecture allows the switch with minimal disruption.

 

3. Omnichannel Consistency

Maintaining consistent messaging across web, mobile, and social media is critical but challenging. Composable architecture makes this easier by syncing tools through APIs. The result is unified data and consistent messaging, regardless of the channel. 

Example: A media company uses a video content platform, another tool for email marketing, and a bespoke app for mobile users. APIs ensure that content updates on the CMS automatically populate across email campaigns and the mobile app, ensuring consistency across channels without manual intervention.

 

4. Breaking Down Silos

Traditional systems often lead to silos between IT and marketing. With a composable approach, marketing gains the flexibility to manage its tools, while IT ensures everything remains secure and scalable. 

Example: A B2B software company uses a CRM like HubSpot, a marketing automation tool, and a data visualisation platform. APIs allow these tools to share data seamlessly, giving both marketing and IT teams a holistic view of campaign performance.

When Should Marketers Push for Composable Architecture? 

How do you know it’s time to opt for composable architecture? Here are some tell-tale signs: 

  • Your Current System Feels Restrictive: If slow updates and limited integrations block your growth, it’s time to change. 
  • Personalisation Isn’t Working: If your campaigns aren’t meeting customer expectations, your tech stack might not be pulling its weight. 
  • Data and Tools Don’t Sync: Siloed systems make it hard to get a unified view of your customer journey. 
  • Scaling Is a Struggle: Growing your business shouldn’t mean battling your technology. 
  • Competitors Are Winning: If others in your industry deliver better digital experiences, composable architecture might be their secret weapon.

How to Get Started 

The beauty of composable architecture lies in its flexibility. You don't need to transform everything overnight. Start with your biggest pain point: 

  1. Replace your rigid CMS with a headless one 
  1. Integrate it with your existing tools 
  1. Add new capabilities as needed 

Each step brings immediate benefits while building towards a more flexible future.
