If you’ve worked in marketing operations for any length of time, you’ve heard the acronyms: POPs, COPs, MIOPs, DevMOPs. The Four Pillars of Marketing Operations framework has been adopted across the MOps community, cited by analysts, vendors, and practitioners alike, and it started here.

Etumos founder Edward Unthank introduced the Four Pillars in 2019 to answer a question that still trips up executives today: what does a complete marketing operations function actually look like? This is the official Etumos answer: what each pillar means, who does the work, and how the framework holds up in the age of AI agents.

What Is Marketing Operations?

Marketing operations is the specialized discipline of running the systems, processes, and data that let a marketing strategy actually execute. It’s embedded technology management: choosing and operating the marketing automation platform, getting campaigns into market, measuring what worked, and building the infrastructure that makes all of it repeatable.

It is not a one-person job, and that’s exactly what the Four Pillars framework makes visible. The responsibilities of marketing operations divide into four distinct specializations, each with its own skill set. All companies need some level of support from each pillar; the mix depends on the scale and complexity of your marketing.

Pillar 1: Platform Operations (POPs)

Platform Operations is the foundation layer: the management of the marketing technology platforms themselves. POPs work includes:

• Marketing automation platform administration (Marketo, HubSpot, MCAE, Eloqua)
• System integrations and the CRM sync
• Lead lifecycle architecture, scoring models, and data management
• Platform implementations and migrations

POPs professionals thrive in the technical guts of the stack: field mappings, sync errors, deduplication logic, and governance. When the platform is healthy, nobody notices. When it isn’t, nothing else in marketing works. That’s why database hygiene and lifecycle architecture are the foundation of good marketing.

Pillar 2: Campaign Operations (COPs)

Campaign Operations is the execution engine: the hands-on creation of your campaigns within your MAP. COPs work includes:

• Email builds, landing pages, forms, and webinar programs
• Campaign QA and testing before anything goes live
• Templatized, repeatable program builds that scale
• Throughput: turning marketing’s calendar into launched campaigns

The hallmark of a mature COPs function is repeatability. The first webinar program might take days to build; with proper templates and a centralized intake process, the fiftieth takes an hour. Campaign Operations turns marketing strategy from a slide deck into something a prospect actually receives.

Pillar 3: Marketing Intelligence Operations (MIOPs)

Marketing Intelligence is how marketing proves, and improves, its impact. MIOPs work includes:

• Funnel and lifecycle reporting: conversion rates, velocity, cohort analysis
• Campaign attribution and ROI measurement
• Dashboards that executives actually use
• Data quality standards that make all of the above trustworthy

Marketing intelligence answers the questions every CMO gets asked: what did we get for the budget, and what should we do more of? In a world of complex customer journeys and disconnected data sources, MIOPs is often the hardest pillar to staff, and the one that earns marketing its seat at the revenue table.

Pillar 4: Marketing Development Operations (DevMOPs)

Marketing Development Operations is the engineering pillar: custom development and sophisticated integrations that extend what the platforms can do out of the box. DevMOPs work includes:

• Custom API integrations and middleware between systems
• Webhooks, custom objects, and advanced data orchestration
• Internal tooling that automates the repetitive work of the other three pillars
• Agent infrastructure: MCP servers, governed AI workflows, and the connective tissue between LLMs and the MarTech stack

Most marketing teams don’t employ a dedicated DevMOPs engineer. The work is often outsourced to consultants or borrowed from engineering. But as AI agents become part of the marketing stack, DevMOPs is shifting from “nice to have” to the pillar that determines how fast everything else can move.

How the Pillars Work Together

The pillars aren’t silos, they’re a dependency chain. Platform Operations keeps the systems trustworthy. Campaign Operations builds on those systems to get campaigns out the door. Marketing Intelligence measures what those campaigns did. Marketing Development extends and automates all three.

A common staffing mistake is hiring one “marketing ops manager” and expecting coverage across all four pillars. One person can be competent in all four; nobody is expert in all four. As marketing complexity grows, the pillars are how you scope roles, write job descriptions, and decide what to keep in-house versus bring in specialists for.

The Four Pillars in the Agentic Era

The framework was built years before LLMs entered the marketing stack, and it’s holding up well because AI agents don’t replace the pillars. They change how the work inside each pillar gets done:

• POPs: agents monitor data quality, flag sync anomalies, and assist platform audits, with humans approving changes to systems of record
• COPs: agents assist program builds and QA against your templates and naming conventions, compressing campaign turnaround time
• MIOPs: agents assemble recurring reports and surface anomalies, so analysts spend time on decisions instead of spreadsheet assembly
• DevMOPs: the pillar that builds the agent layer itself (MCP integrations, permission models, and evaluation frameworks)

The operational discipline the Four Pillars demands (governance, templates, naming conventions, QA) is exactly what makes agentic marketing operations safe to deploy. Teams that skipped the fundamentals are discovering that AI amplifies whatever operational state you’re in: mature operations get faster, messy operations get messier.

Frequently Asked Questions

What are the four pillars of marketing operations?

The four pillars are Platform Operations (POPs), Campaign Operations (COPs), Marketing Intelligence Operations (MIOPs), and Marketing Development Operations (DevMOPs). The framework was created by Edward Unthank, founder of Etumos, and has been widely adopted across the marketing operations community.

Who created the Four Pillars of Marketing Operations framework?

Edward Unthank, founder of Etumos, introduced the framework in 2019. It has since been referenced throughout the MOps community and by marketing technology vendors as the standard model for structuring marketing operations teams.

Does one person cover all four pillars?

In small teams, one marketing ops professional often covers all four at a generalist level. As complexity grows, the pillars become distinct roles or teams, and most organizations bring in specialists for the pillars they can’t staff, particularly Marketing Intelligence and DevMOPs.

How does AI change the four pillars?

AI agents accelerate work within each pillar rather than replacing the pillars themselves. Agents assist with data quality, campaign builds, and reporting, while DevMOPs expands to include agent infrastructure like MCP integrations and governance frameworks.

How do I know which pillar my team needs most?

Look at where work is stuck. Campaigns slow to launch points to COPs; unreliable data points to POPs; no credible ROI reporting points to MIOPs; manual work that should be automated points to DevMOPs. A structured tech stack health audit identifies the gaps quickly.

Work With the Team That Wrote the Framework

Marketing operations is what we do, across all four pillars, since before the framework had a name. Whether you need a tech stack health audit, campaign operations support, or a roadmap for agentic marketing operations, let’s talk.
