Marketing: In-house or external through an agency? A comprehensive and neutral review

Why does this question even arise?

This question regularly preoccupies marketing managers and CEOs. Should marketing be developed internally or outsourced to an external agency? The discussion is legitimate, as both approaches have their advantages and disadvantages. But as with many decisions, there is no one-size-fits-all solution. The answer depends on many factors, but above all on one: the people who implement the marketing.

What makes choosing one model or the other sensible? First, the company's goals must be clarified. Are they looking for continuous marketing measures or project-based campaigns? What budgets are available? How important is direct control over marketing activities?

The discussion is often conducted on a superficial level, overlooking the fact that both in-house teams and agencies are only as good as the people who work there. A motivated, passionate employee can achieve extraordinary things in both a company and an agency. An employee who simply goes through the motions will not achieve the desired success either.

What are the advantages of in-house marketing?

The advantages of the internal solution

An internal marketing team offers several undeniable advantages. First, there's a deep connection to the company. In-house employees often know the corporate culture, products, and target audiences better than external service providers. They interact with the brand on a daily basis and, over time, develop an intuitive understanding of the right communication.

Communication channels are significantly shorter. When quick decisions need to be made, internal teams can react immediately. There's no need to prepare briefings, coordinate external appointments, or go through lengthy coordination loops. This agility can be a decisive advantage, especially in dynamic markets.

Complete control is another key aspect. The company determines how resources are allocated, what priorities are set, and the direction of marketing. This control also extends to costs. Instead of project-related agency fees, predictable fixed costs arise from salaries and infrastructure.

The challenges of internal teams

But an in-house team also brings challenges. Building a competent marketing team is time-consuming and costly. Qualified marketing specialists are highly sought after in the job market. Many consciously choose the creative environment and variety offered by agencies.

The costs are often higher than initially estimated. In addition to salaries, social security contributions, office equipment, software licenses, and training costs are added. A full marketing team with all the necessary specializations can quickly become expensive.

Another problem is limited expertise. An internal team can't be equally strong in all marketing disciplines. Specialized knowledge in areas like SEO, performance marketing, or creative design is often limited. This can lead to suboptimal results or the need for additional external support.

What are the advantages of external agencies?

The strengths of external service providers

Agencies bring specialization. They have experts in various marketing disciplines – from strategy and creation to performance marketing. This expertise has been built up over years and is continuously developed. Agencies invest in the latest tools and technologies that a single company often cannot or does not want to afford.

Industry experience is another advantage. Agencies work with diverse clients from different industries. They are familiar with best practices, have solved various challenges, and can leverage this knowledge. This external perspective can lead to innovative solutions that internal teams might not have developed.

Flexibility in resource planning is particularly attractive for smaller companies. Instead of maintaining a full in-house team, resources can be scaled as needed. Costs are lower during quieter periods, and larger projects can be expanded quickly.

The disadvantages of the agency solution

External agencies also have weaknesses. Their distance from the company can be problematic. Agency employees often don't know the internal processes, corporate culture, or specific challenges as well as internal staff. This can lead to misunderstandings or less targeted measures.

Longer communication channels are unavoidable. Briefings must be prepared, deadlines coordinated, and feedback loops completed. This takes time and can be a hindrance in fast-moving situations.

Dependence on external service providers carries risks. If an agency changes its working practices, loses key personnel, or the partnership is terminated, the company may be left without a functioning marketing structure. The knowledge and experience it has built up are lost.

The decisive factor: The human

Passion versus service by the book

The decision between in-house and agency work is often made at the wrong level. It's not primarily about structures or cost models, but rather about the people who implement marketing. A passionate employee will achieve excellent results both in an in-house team and in an agency. An employee who just goes through the motions will perform disappointingly in both environments.

Passion in marketing is more than just a fancy word. It's expressed in the willingness to go beyond the bare minimum, develop creative solutions, and continuously improve. Passionate employees identify with their tasks and the company. They are intrinsically motivated and work not just for the salary, but for the success of the cause.

The opposite pole is the "jobber" – an employee who puts down their pen at 5 p.m. sharp and only does what's necessary. Recent studies show that 78 percent of German employees are just doing their work by the book. This mental resignation is a problem for both companies and agencies.

How do passionate employees emerge?

Passion doesn't happen automatically. It must be nurtured and maintained. Both companies and agencies have a responsibility here. Leadership plays a crucial role. Employees need appreciation, clear goals, and the opportunity to develop further.

Intrinsic motivation is more sustainable than extrinsic incentives. While bonuses and rewards can provide short-term motivation, long-term enthusiasm comes from meaningful tasks, autonomy, and opportunities for personal development. Employees want to understand why their work is important and how it contributes to overall success.

The work environment is also crucial. A supportive, appreciative environment promotes motivation. Micromanagement, a lack of perspective, or poor leadership, on the other hand, can demotivate even passionate employees and lead them to work by the book.

The third component: Artificial Intelligence

AI as a game changer in marketing

In recent years, a third component has entered the marketing conversation: artificial intelligence. AI is fundamentally changing the way marketing is conducted. It can automate processes, analyze data, create content, and optimize campaigns. Both in-house teams and agencies must grapple with this technology.

AI offers enormous potential. It can analyze large amounts of data in seconds, identify patterns, and make predictions. Personalized advertising, automated content creation, and dynamic pricing are just a few examples of AI applications in marketing. The efficiency gains can be significant.

At the same time, AI also poses risks. Data protection, bias in algorithms, and the danger of generic content are challenges that must be addressed. AI can provide creative stimulus, but it cannot completely replace human creativity and emotional intelligence.

The initiator makes the difference

This demonstrates once again: humans remain the decisive factor. AI is only as good as the person who drives it. A passionate marketing expert will use AI tools creatively and strategically. They will ask the right questions, critically evaluate the results, and incorporate human elements where necessary.

An employee without passion may use AI only superficially. They will use standardized prompts, accept results without reflection, and fail to utilize the technology's full potential. AI will then become just another tool for doing things by the book, rather than a lever for exceptional results.

Providing impetus is crucial. AI requires clear objectives, well-thought-out strategies, and creative approaches. It can support marketers in generating ideas, creating variations, and accelerating processes. But the strategic direction, creative vision, and emotional connection with the customer must still come from humans.

Which solution is the right one?

It depends on the circumstances

There's no simple answer to the question of whether to go in-house or with an agency. Both models can be successful – if the right people are involved and the framework is right. For continuous marketing activities and long-term brand management, there's a lot to be said for an in-house team. For specialized projects or when in-house expertise is lacking, an agency may be the better choice.

Many successful companies rely on a hybrid model. A small in-house team takes on strategic leadership and ongoing tasks. An agency is brought in for special projects, creative campaigns, or technical implementations. This creates the best of both worlds.

Company size also plays a role. Larger companies are more likely to be able to afford a full in-house marketing team. Smaller companies often rely on external support or gradually build up internal capabilities.

The importance of leadership

Regardless of the chosen model, leadership is crucial. Both internal teams and external agencies need clear goals, regular feedback, and appreciation for their work. Leaders must understand that marketing is a creative process that requires time and freedom.

Sustainable employee management means maintaining motivation over the long term. This isn't achieved through constant motivational events or superficial benefits, but rather through a work environment that fosters intrinsic motivation. Employees want to see meaning in their work, be able to develop further, and be valued as people.

Micromanagement is the enemy of motivation. Both internal teams and agencies need trust and freedom to work creatively. Excessive control leads to a "do-it-yourself" approach and hampers exceptional results.

The future of marketing

Technology and humanity

The future of marketing will be shaped by the combination of technological capabilities and human creativity. AI will take over many routine tasks and open up new possibilities for data analysis and personalization. At the same time, human skills such as empathy, creativity, and strategic thinking will become more important than ever.

Both in-house teams and agencies must adapt to these changes. They must learn how to use AI tools effectively without losing the human element. The trick is to use technology as an amplifier of human capabilities, not as a replacement.

The most successful marketing organizations of the future will be those that are both technologically savvy and human-centric. They will strategically use AI to drive better results, but always with a focus on authentic, emotional connections with their audiences.

Continuous learning as a success factor

The marketing landscape is changing rapidly. New platforms, technologies, and consumer habits are constantly emerging. Both internal teams and agencies must be prepared to constantly learn and adapt. This requires a culture of continuous learning and experimentation.

Continuing education is becoming a critical success factor. Marketing professionals need to not only expand their professional skills but also develop technical proficiency in using AI tools. At the same time, soft skills such as communication, collaboration, and critical thinking are becoming increasingly important.

Companies and agencies that invest in the development of their employees will be more successful in the long run. They create an environment where passion and competence can flourish – regardless of whether marketing is organized internally or externally.

People decide

The discussion about in-house marketing versus external agencies is often conducted with the wrong focus. Cost comparisons and organizational structures are important, but not crucial. Success depends primarily on the people implementing the marketing – their skills, motivation, and passion for the cause.

A passionate employee will excel both in an in-house team and at an agency. They will leverage AI tools creatively, continuously learn, and go above and beyond the required minimum. A disengaged employee will perform mediocrely in both environments – no matter how good the structure or available tools.

The trick lies in finding the right people, managing them properly, and creating an environment where passion and creativity can flourish. Both companies and agencies have a responsibility here. They must understand that sustainable motivation doesn't come from incentives or pressure, but from meaningful tasks, appreciation, and development opportunities.

AI will continue to transform marketing and open up new possibilities. But here, too, the technology is only as good as the people who control it. A strategically thinking, creative driver will drive AI to exceptional results. An unmotivated user will only achieve mediocre results, even with the best tools.

The decision between in-house and agency work should therefore not be based primarily on cost separation or organizational models, but rather on the question: Where can I find the best people for my marketing? And how can I ensure that they can work motivated and successfully in the long term?

In a world where technology is becoming increasingly important, people remain the key to success. Companies and agencies that understand this and act accordingly will achieve more successful marketing results in the long run – regardless of their chosen organizational structure.
