Outsourced Marketing Services: What B2B Companies Should Expect in 2026

Outsourced Marketing Services: What B2B Companies Should Expect in 2026

More than half of UK B2B companies now outsource part or all of their marketing function, according to Full Mix Marketing. That figure will only grow. The global outsourced marketing market is projected to reach $74.76 billion by 2034, up from $25.4 billion in 2024, based on data from Flowium. But the reasons companies buy outsourced marketing services have changed significantly, and the models available in 2026 look very different from those offered even two years ago.

This guide covers the current state of outsourced marketing, the five main delivery models now available, what services a competent provider should include, and how to evaluate whether an outsourced marketing agency is worth the investment.

The Market Has Shifted from Cost to Capability

For years, the primary appeal of outsourced marketing was simple: it saved money. Deloitte's 2025 Global Outsourcing Survey found that brands outsourcing saved up to 38% in operational costs. That still matters. But as Deloitte also noted, "cost is a deteriorating value proposition" for outsourcing, with organisations now prioritising skilled talent and agility over savings alone.

Several forces are driving this shift. Marketing budgets have flatlined at 7.7% of revenue according to Gartner, and 63% of CMOs cite budget constraints as their top challenge. At the same time, 39% of CMOs are cutting agency budgets. The result is a squeeze: companies need more marketing output with fewer resources, and they need it delivered by people who actually know what they are doing.

The skills gap makes this worse. Research from the Chartered Institute of Marketing and Hays found that 88% of UK marketing employers experienced skills shortages. CIM also reported that 78% of CMOs expect budgets to remain stable or grow but lack cross-functional AI and digital skills internally. As Christy Ferguson of Gartner put it, "CMOs are under increasing pressure to deliver measurable growth in 2026, despite budget constraints".

This is why 80% of executives plan to maintain or increase outsourcing investment, according to Deloitte. The commercial logic has moved from "we can't afford a team" to "we can't build the right team fast enough".

Five Outsourced Marketing Models Available in 2026

Not all outsourced marketing services work the same way. The model you choose should match your commercial stage, internal capability, and growth ambitions.

Retained Monthly Retainer

The most common arrangement. You pay a fixed monthly fee, typically between £1,000 and £8,000, for a defined scope of work. This suits companies that need consistent output across content, SEO, or digital marketing but have internal leadership to direct the work. The limitation is that retained arrangements often lack strategic depth. You get execution, but not always someone asking whether the execution is aimed at the right objectives.

Embedded Outsourced Marketing Department

An outsourced team operates as a full marketing function within your business. Monthly investment ranges from £5,000 to £10,000, covering strategy, planning, and production. This model works for growth-stage B2B companies that need senior thinking and hands-on delivery without hiring a full department. At Forge Together, this is how we work with clients: the team sits inside the business, attends leadership meetings, and owns the marketing plan alongside the founders.

Project-Based

Ideal for defined campaigns, product launches, or market entry work. You scope, price, and deliver against a fixed brief. The advantage is clarity. The risk is that marketing rarely operates in isolation, and project-based work can miss the broader commercial context.

Performance-Based

According to IMS Nhance, 58% of brands are shifting towards performance-based models, where fees are tied to measurable outcomes such as leads generated, pipeline influenced, or revenue attributed. This model demands mature tracking infrastructure and clear agreement on what counts as a result. Without that, disputes follow quickly.

Hybrid In-House and Outsourced

Research from Bruce Clay indicates that 46% of B2B organisations plan to adopt a hybrid model by 2026. This blends internal marketing staff with an outsourced marketing team that fills capability gaps. It is often the most practical option for companies with one or two marketers who need specialist support in areas such as SEO, PR, or marketing automation.

What Outsourced Marketing Services Should Include

A credible outsourced marketing department should cover the full spectrum of B2B marketing, not just the bits that are easy to productise.

• Strategy and Planning: Market positioning, audience segmentation, messaging frameworks, and quarterly planning cycles. Without this, everything else is activity without direction.
• Content Marketing: Blog content, thought leadership, case studies, and sales enablement materials. Content should be tied to a keyword strategy and mapped to the buyer journey, not produced as a volume play.
• SEO and AI Visibility: Technical SEO audits, on-page optimisation, link building, and structured content for AI search. HubSpot found that 61% of marketers believe marketing is experiencing its biggest disruption in 20 years due to AI. Any provider ignoring AI visibility in 2026 is already behind.
• Digital Marketing: Paid search, paid social, email marketing, and conversion rate optimisation. These channels need continuous management and budget discipline, which is where outsourced specialists often outperform generalist in-house hires.
• PR and Communications: Media relations, press releases, contributed articles, and awards programmes. B2B PR is a long game that requires established journalist relationships, something most companies cannot build in-house quickly.
• Marketing Automation: CRM integration, lead scoring, nurture sequences, and reporting dashboards. Automation without a strategy behind it just creates noise faster.

How to Evaluate an Outsourced Marketing Agency

Before signing a contract, apply these filters to any outsourced marketing services provider.

• Ask for their strategic process. If they jump to tactics before understanding your market position, competitive set, and commercial goals, they are an execution shop, not a marketing partner.
• Check for B2B-specific experience. B2B marketing has longer sales cycles, multiple decision-makers, and complex propositions. Agencies that primarily serve consumer brands will struggle with this, regardless of how polished their pitch deck looks.
• Demand transparency on who does the work. Many agencies sell senior expertise in the pitch and then hand delivery to junior staff. Ask who will attend your meetings and who will produce the work.
• Look at reporting rigour. Monthly reports should tie marketing activity to commercial outcomes: pipeline generated, conversion rates, and cost per lead. Vanity metrics such as impressions and follower counts should be context, not headline numbers.
• Assess cultural fit. The best outsourced marketing arrangements feel like an extension of the internal team. If the agency does not invest time in understanding your business, products, and customers, the output will always feel generic.

What Comes Next

Outsourced marketing services in 2026 are defined by capability, not cost savings. The UK outsourcing services market alone is expected to reach $387.3 billion by 2030 at a 10.2% CAGR, according to Grand View Research. The trend is clear, and the companies that benefit most will be those that choose the right model and the right partner.
