Agencies can be a brand’s biggest growth accelerators—or its most frustrating roadblocks. For marketing leaders, the challenge isn’t just choosing the right agency but knowing how to manage the relationship effectively.

Many brands struggle with agencies that overpromise and underdeliver, misalignment between internal goals and agency execution, and a lack of transparency on performance. But when managed well, agency relationships can drive better marketing outcomes, unlock new growth opportunities, and free up internal teams to focus on strategic priorities.

This article explores how marketing leaders can build stronger, more productive partnerships with their agencies—from selection and onboarding to collaboration, accountability, and knowing when it’s time to move on.

Choosing the Right Agency: More Than Just a Good Pitch

The team that sells you an agency’s services isn’t the team you’ll actually work with. Yet, too many brands make hiring decisions based on impressive pitches rather than assessing the day-to-day team responsible for execution.

Before signing any contract, marketing leaders should insist on meeting the core team—account managers, strategists, and execution leads—who will be responsible for the work. Cultural fit, industry experience, and a clear understanding of your brand’s growth stage are just as critical as a strong pitch deck.

Red Flags to Watch Out For:

• Unrealistic promises: If an agency guarantees specific KPIs, be wary—marketing performance is never a guarantee.
• Lack of category experience: If they don’t understand your industry, they’ll struggle to craft high-performing campaigns.
• Rigid pricing models: Look for flexibility, especially if your needs evolve over time.
• Transactional mindset: The best agencies act as long-term partners, not just vendors.

A strong agency fit goes beyond expertise—it’s about shared values, aligned incentives, and a team that works as an extension of your brand.

Setting Clear Expectations for Success

A great agency relationship starts with clear expectations. Without well-defined goals and benchmarks, even the best agency can struggle to deliver meaningful results.

Key Areas to Align on From Day One:

1. Performance Metrics: Establish KPIs that truly reflect business objectives, not just vanity metrics like impressions or clicks.
2. Reporting & Insights: Define how often reports will be delivered, what they should include, and how performance will be evaluated.
3. Scope of Work: Clearly outline what’s included (and what’s not) to prevent scope creep and unexpected costs.
4. Collaboration Expectations: Set communication cadences, feedback loops, and escalation processes upfront.

One common pitfall? Incentive misalignment. Some brands push for performance-based contracts, but these can create short-term thinking and misaligned priorities. Agencies should be accountable for driving results, but they also need the flexibility to test, optimize, and execute long-term strategies without constant pressure to justify their existence.

Building a Collaborative & Transparent Partnership

The best agency relationships feel like true partnerships, where both sides share knowledge, insights, and a commitment to success. Yet, too often, brands treat agencies as external vendors rather than integrated team members.

How to Build a Stronger Agency Relationship:

• Create shared accountability. Agencies perform best when they understand the bigger picture, not just their assigned channel.
• Foster open communication. Regular check-ins, collaborative planning, and transparent discussions lead to better outcomes.
• Provide strategic context. Agencies need to know how their work fits into broader business objectives to make informed decisions.
• Empower, don’t micromanage. Trust your agency to execute—while ensuring they remain aligned with your goals.

Agencies do their best work when they feel valued, trusted, and fully integrated into your team’s success.

The Power of Knowledge Sharing & Cross-Agency Alignment

Most brands don’t rely on a single agency. They work with multiple partners across different areas—paid media, PR, creative, SEO, and influencer marketing. But when these agencies operate in silos, valuable insights are lost, and performance suffers.

Common Problems with Disconnected Agency Teams:

• Redundant efforts: PR and paid teams targeting the same audience without coordination.
• Data silos: One agency uncovers a valuable insight, but it never reaches the others.
• Inefficiencies: Multiple agencies pulling in different directions instead of working toward a unified strategy.

How to Improve Cross-Agency Collaboration:

• Host regular all-agency meetings to align on strategy, learnings, and priorities.
• Use shared dashboards to track multi-channel performance in one place.
• Encourage agencies to work together rather than compete for influence.

The best brands build agency ecosystems where partners work together seamlessly, leading to more cohesive marketing strategies and better business outcomes.

Keeping Agencies Accountable Without Micromanaging

Accountability is critical, but too much oversight can stifle creativity and lead to an unproductive working relationship. The key is striking a balance—tracking performance while giving agencies the space to execute effectively.

How to Hold Agencies Accountable (Without Driving Them Crazy):

• Define clear success metrics. Set KPIs that reflect business impact, not just marketing outputs.
• Structure performance reviews. Regular evaluations should be constructive, with a focus on optimization rather than blame.
• Allow time for strategies to play out. Not every campaign will deliver immediate results—some require iteration and patience.
• Provide actionable feedback. Instead of saying “this isn’t working,” offer specific insights on what needs improvement.

Agencies thrive when they’re challenged to deliver results but are also given the flexibility to innovate and optimize.

Knowing When (and How) to Change Partners

No agency relationship lasts forever. Sometimes, despite best efforts, an agency isn’t the right fit. The key is recognizing the signs early and making a transition without disrupting performance.

Signs It’s Time to Move On:

• Lack of transparency in reporting
• Declining performance with no clear solutions
• Slow response times and poor communication
• Misaligned priorities or strategic disagreements

How to Transition Smoothly:

• Have a clear exit plan: Define timelines, handoff processes, and knowledge transfer expectations.
• Minimize disruption: Ensure the transition doesn’t negatively impact ongoing campaigns.
• Onboard the new agency with clarity: Set them up for success with detailed briefs, historical data, and strategic context.

Changing agencies isn’t a failure—it’s part of refining your marketing approach and ensuring you have the right partners to support your brand’s growth.

Conclusion

Managing agencies effectively is one of the most valuable skills a marketing leader can develop. When done right, strong agency partnerships lead to better marketing performance, greater efficiency, and a more scalable brand strategy.

Key Takeaways:

• Choose agencies based on real capabilities, not just a great sales pitch.
• Set clear expectations upfront to align on goals, KPIs, and collaboration processes.
• Foster transparency and open communication to make agencies feel like part of the team.
• Encourage knowledge sharing between agencies to create a unified marketing strategy.
• Hold agencies accountable while allowing space for creativity and long-term thinking.
• Recognize when it’s time to change partners, and manage transitions smoothly.

Marketing leaders who master agency management don’t just improve campaign performance—they build high-functioning ecosystems where agencies operate as true growth partners. If your agency relationships aren’t delivering the results you need, it may be time to rethink how you’re managing them.
