Marketing and communications have always shared common ground. Today, the overlap is even greater. Brand, content, reputation, executive visibility, and digital channels all touch both functions, making it increasingly difficult to draw clear lines around who owns what. For organizations with both a Chief Marketing Officer (CMO) and a Chief Communications Officer (CCO), the challenge isn’t simply defining responsibilities. It’s making sure two critical functions work together without duplicating efforts, competing for influence, or sending conflicting messages.
The solution isn’t necessarily to combine the roles. It’s to establish clear ownership, shared priorities, and a strong working relationship between the two leaders.
Where Marketing and Communications Overlap
Some responsibilities are relatively straightforward. Marketing typically focuses on customer acquisition, demand generation, brand positioning, and revenue growth. Communications generally focuses on corporate messaging, stakeholder engagement, media relations, and protecting organizational reputation. But the lines get blurry in several important areas:
Brand and reputation – Marketing often leads brand positioning, identity, and the customer experience. Communications helps shape how the organization is perceived by employees, investors, the media, and other stakeholders. Both influence the company’s reputation, but from different perspectives. Marketing may focus on building preference and loyalty among customers, while communications considers the broader factors that influence trust and credibility.
The two functions need to align on what the brand stands for and how those values show up across audiences. A compelling marketing campaign won’t overcome a disconnect between what a company promises and how it behaves.
Content and messaging – Both teams create content, develop messaging, and tell stories about the organization. Marketing may focus on campaigns, product launches, and customer engagement. Communications focuses on corporate narratives, executive messaging, thought leadership, media materials, and internal communications.
The distinction isn’t always about who writes the content. It’s about the audience, objective, and potential implications of the message. Without coordination, organizations risk producing competing narratives or repeating work across departments. A shared content strategy and clear approval process can help ensure that every communication supports the broader business story.
Executive visibility and thought leadership – Who owns the CEO’s voice? Communications is typically responsible for positioning executives as industry experts through thought leadership, digital content, and speaking opportunities. The CCO also often manages executive messaging, media interviews, public appearances, and relationships with key stakeholders.
Both functions have a legitimate role here though. The CEO shouldn’t have to navigate two separate strategies. Executive visibility works best when marketing and communications agree on the message, the audience, and the desired outcome.
Crisis response and reputation management – This is where unclear ownership can become especially problematic. Communications typically leads media response, corporate statements, stakeholder updates, and counsel to senior leadership. Marketing may be responsible for customer-facing messaging and campaign adjustments during a crisis. In a general sense, the CCO should lead corporate crisis communications and reputation response, working closely with the CEO, legal team, and other relevant leaders. Marketing should be integrated into the response when customers, products, or brand campaigns are affected.
So, Who Should Own What?
There is no universal organizational model, and responsibilities will vary by company. However, a practical starting point is to establish a primary owner for each area while identifying where collaboration is essential.
Brand strategy: Marketing leads brand positioning and customer-facing brand development; communications helps ensure alignment with corporate identity and reputation.
Corporate reputation: Communications leads reputation strategy and stakeholder messaging, with marketing contributing customer and market insights.
Content and storytelling: Each function owns content for its primary audiences, supported by shared messaging and editorial planning.
Executive visibility: Communications leads executive messaging and media strategy; marketing supports thought leadership, digital distribution, and audience engagement.
Crisis response: Communications leads corporate crisis communications, with marketing responsible for coordinated customer and brand-related actions.
Internal communications: Often led by communications or HR, depending on the organization, with marketing contributing when employee brand or culture initiatives are involved.
Measurement: Marketing tracks metrics tied to customer engagement, pipeline, and growth. Communications measures outcomes such as stakeholder engagement, message effectiveness, trust, and reputation, using metrics appropriate to the business.
The goal isn’t to create rigid boundaries around every activity. It’s to eliminate uncertainty about who makes decisions, who needs to be consulted, and who is accountable for the outcome.
How CMOs and CCOs Can Work Better Together
Even the clearest organizational chart won’t solve the problem if the leaders operate independently. The relationship between the CMO and CCO needs to be intentional.
1. Establish shared business priorities. Both leaders should understand the organization’s most important objectives, whether that’s entering a new market, managing a leadership transition, strengthening reputation, or driving growth. Their strategies should support those priorities rather than compete for resources and attention.
2. Agree on decision-making authority. Collaboration doesn’t mean every decision requires consensus. Define who has final authority over key areas, where consultation is necessary, and how disagreements will be resolved. This becomes particularly important when reputational risk and commercial objectives pull in different directions.
3. Create regular opportunities to coordinate. The CMO and CCO shouldn’t meet only when a problem arises. Regular planning conversations can help them anticipate announcements, align messaging, coordinate content, and identify potential risks before they become larger issues.
4. Build complementary teams. The two leaders don’t need identical skill sets or overlapping departments. They need teams with distinct expertise that can work together effectively. That requires understanding each function’s capabilities, avoiding unnecessary duplication, and identifying where shared resources make sense.
5. Measure success without losing sight of the bigger picture. Marketing and communications will have different performance metrics, and they should. But both leaders should recognize that their work contributes to the organization’s overall success. Strong marketing can build awareness and demand; strong communications can strengthen trust and protect the reputation that makes long-term growth possible.
The Leadership Question Behind the Org Chart
When marketing and communications responsibilities overlap, the instinct may be to reorganize the departments or reconsider whether both executive roles are necessary. Sometimes structural change is the right answer. Often, the bigger issue is a lack of clarity about leadership, accountability, and expectations.
A strong CCO understands that reputation and stakeholder trust are closely connected to business performance. A strong CMO understands that growth depends on more than campaigns and customer acquisition. Both need to see beyond their individual functions and understand how their decisions affect the organization as a whole.
When evaluating either role, companies should consider not only a candidate’s functional expertise but also their ability to collaborate across the C-suite, navigate competing priorities, and build productive relationships with other senior leaders. The question isn’t whether marketing or communications owns the gray areas. It’s whether the organization’s leaders have agreed on how to manage them.
