Job function and seniority targeting for B2B campaigns

Why two axes, not one?

Most B2B campaigns are built around a single targeting variable. "Target Marketing Directors." "Target IT decision-makers." The problem is that "Marketing Director" tells you two things at once: the function (Marketing) and the seniority (Director). When the campaign underperforms, it is often impossible to diagnose whether the function was wrong, the seniority was wrong, or both.

Splitting the two axes gives you a proper grid. If the Finance function produces twice the open rate of the IT function at Director level, you know it is a function effect. If Manager cells outperform Director cells across all functions, the seniority band was off. Without the grid, you are guessing.

The UK B2B data market broadly maps to seven functions and four to five seniority bands. That gives 28 to 35 cells, each representing a distinct type of contact. Most single campaigns should target no more than four to six cells, chosen specifically for the product and deal type.

The function taxonomy: seven standard categories

UK company structures vary enormously by size, sector, and ownership, but the following seven functions cover the vast majority of B2B buying committee members you will encounter in the UK market. The labels below are the data-file conventions; actual job titles mapped into each function can number in the hundreds.

CEO/MD (General Management)

Includes Chief Executive Officers, Managing Directors, and their equivalents (Chief Operating Officers at smaller firms, Executive Directors, Group MDs). This function is the final-authority node for most significant purchases in businesses below around 200 staff. Above that headcount, purchasing decisions fragment across functional leaders. Targeting CEO/MD at a 50-person firm makes sense for a £20,000-per-year contract; targeting the CEO of a FTSE 250 is rarely productive unless your product is genuinely board-level.

Finance (CFO, Finance Director, Financial Controller)

Finance contacts hold budget authority across almost every category. Even when they are not the primary user or technical evaluator of a product, they appear in most buying committees for contract values above roughly £5,000 per year. The Finance function is also the right audience for products like accounting software, payroll, expense management, invoice financing, and insurance.

Marketing (CMO, Marketing Director, Head of Marketing)

Marketing contacts are the primary audience for MarTech, advertising platforms, design services, PR agencies, data and analytics tools, and event services. They are secondary contacts in many other categories (they will often be consulted on anything that affects brand or communications). The function is smaller in headcount than IT or Operations at most UK firms, so available volumes are lower.

IT (CTO, IT Director, Head of IT, IT Manager)

IT contacts are the technical evaluators and gatekeepers for most SaaS and technology purchases. In organisations above about 100 staff, no software contract closes without IT sign-off, even if the primary budget sits in another function. IT is one of the highest-volume functions in UK B2B data files, and consequently one of the most competed-for.

HR (CHRO, HR Director, Head of HR, HR Manager)

HR contacts are the primary audience for recruitment tools, payroll, HR software, employee benefits, training and L&D, occupational health, and wellbeing products. They appear in buying committees for workplace compliance, legal services, and physical workspace products. Like Marketing, the function is relatively small in headcount at most UK organisations.

Operations (COO, Operations Director, Head of Operations)

Operations is the broadest function and the hardest to define precisely. It covers supply chain, logistics, facilities, production, quality, and general management of day-to-day business processes. In manufacturing, distribution, and field-services businesses, the Operations function is the primary audience for fleet management, warehouse management, field-service software, and procurement tools.

Sales (CSO, Sales Director, Head of Sales, Sales Manager)

Sales contacts are the primary audience for CRM platforms, sales engagement tools, territory mapping, incentive compensation software, and sales training. They also appear in buying committees for data products (because their team is usually the end user of prospecting lists), telephony, and event services.

The seniority taxonomy: four working bands

Seniority in B2B data files is mapped from job title onto a hierarchy. The four practical bands for UK B2B targeting are as follows.

C-suite covers titles starting with "Chief" (CEO, CFO, CTO, CMO, CHRO, COO, CSO) plus the UK equivalents: Managing Director, Group Finance Director, Group IT Director. These contacts have full budget authority and final signing rights. They are hard to reach by cold email (low reply rates, high assistant filtering), expensive to target, and typically relevant only for large contract values or strategic partnership conversations.

Director covers titles like Finance Director, IT Director, Marketing Director, and Operations Director. In UK firms below around 500 staff, Directors often combine strategic authority with hands-on responsibility. They are more reachable than C-suite but still have high inbox competition. The Director band is usually the right primary target for products with an average contract value above £10,000 per year.

Head of is the most productive seniority band for many UK B2B campaigns, though it is often overlooked in favour of Director. A Head of IT, Head of Marketing, or Head of Operations typically has day-to-day ownership of the problem your product solves, has either direct budget authority or strong budget influence, and is significantly more reachable by cold email than Director or C-suite contacts. In our experience, response rates on cold direct mail and cold email to verified Head-of contacts beat C-suite contacts by a factor of two to three, across most product categories.

Manager (IT Manager, Marketing Manager, Finance Manager) is the right primary target for product-led and self-serve SaaS, for enablement tools, and for higher-volume, lower-value products. Managers have limited or no budget authority for large contracts, but they are frequently the person who identifies the problem and advocates internally for a solution. Ignoring the Manager band means missing the person who might champion your product upwards to the Head or Director.

A fifth band, Individual Contributor (IC), covers analysts, developers, coordinators, and specialist practitioners. ICs rarely have budget authority but can be powerful internal advocates. They are most relevant for product-led growth campaigns (free trials, freemium tools) and developer-tools marketing.

The 7x4 function-seniority grid

The table below maps all seven functions against four primary seniority bands and notes the typical use case for each cell. Cells marked "primary" are the right first port of call for most products in that category; cells marked "committee" appear in the buying decision but are not usually the opening contact; cells marked "limited" have constrained volume or weak purchasing authority for most categories.

Function	C-suite	Director	Head of	Manager
CEO/MD	Primary for deals £20k+ in SMEs (<200 staff). Low volume in large firms. Committee member for board-level products.	Not a standard cell (MD is C-suite). Limited use.	Not applicable for this function.	Not applicable for this function.
Finance	CFO: committee member for most large purchases. Primary for treasury, banking, and financial services products.	Finance Director: primary target for accounting, payroll, and spend-management products. Committee member for all significant contracts.	Head of Finance: strong for mid-market, particularly where the FD is absent or not decision-making. Good for finance software, invoice automation.	Finance Manager: primary for transactional and subscription finance tools. Limited authority for capex decisions.
Marketing	CMO: primary for enterprise MarTech, agency relationships, and brand strategy services. Low volume outside FTSE 500.	Marketing Director: primary for mid-market MarTech, data tools, and marketing agency services.	Head of Marketing: often the most responsive cell for MarTech and data products. Combines authority with day-to-day pain.	Marketing Manager: primary for self-serve tools, templates, and creative services. Limited for platform-level contracts.
IT	CTO/CIO: primary for enterprise software and infrastructure. Committee for all SaaS above a low contract threshold.	IT Director: primary for mid-market technology procurement. High inbox competition; direct mail often outperforms email for this cell.	Head of IT: frequently the working decision-maker for technology purchases at firms of 50-500 staff. Underused by many campaigns.	IT Manager: technical evaluator and internal champion. Rarely signs contracts but heavily influences vendor selection. Primary for developer tools and security products.
HR	CHRO: primary for enterprise HR platforms, executive recruitment, and strategic workforce products.	HR Director: primary for HR software, payroll, and benefits platforms. Committee for anything affecting people management.	Head of HR: often the budget holder for HR tools at mid-market firms. Good response rates; lower inbox competition than IT/Finance.	HR Manager: primary for recruitment tools, training platforms, and compliance products. High volume, moderate authority.
Operations	COO: primary for operational transformation projects and enterprise supply chain. Committee for most large capital purchases.	Operations Director: primary for fleet, logistics, facilities management, and field-service products.	Head of Operations: often the most directly responsible contact for operational pain in manufacturing and distribution. Strong primary target for operational SaaS.	Operations Manager: primary for scheduling, workforce management, and compliance tools. High volume in sectors like logistics, hospitality, and retail.
Sales	CSO/VP Sales: primary for enterprise CRM and revenue intelligence platforms.	Sales Director: primary for CRM, sales engagement, and territory planning tools at mid-market firms. Also key audience for B2B data products.	Head of Sales: strong cell for CRM and prospecting tools. Good response rates and direct ownership of the sales process.	Sales Manager: primary for individual sales tools, coaching platforms, and incentive compensation. Committee for team-level tools.

What are the most common targeting mistakes?

Over-broad targeting

The single most expensive mistake is buying a list of "all decision-makers" without function or seniority filters. A 10,000-record list of mixed-function, mixed-seniority contacts will typically include thousands of contacts with no relevance to your product, and the response rates will average down to something discouraging. You will conclude that B2B outreach does not work, when the reality is that unfiltered lists do not work.

Function-only targeting

Selecting a function without a seniority filter produces a list with vast internal variation in authority and role. A "Marketing" list that includes CMOs, Marketing Managers, Social Media Executives, and junior coordinators will need four completely different messages to have any chance of resonating. Running one message to all of them typically means the message fits none of them well.

Seniority-only targeting

Targeting "Directors" across all functions is the mirror error. Your campaign now includes Finance Directors, IT Directors, HR Directors, Sales Directors, and Operations Directors. Unless your product is genuinely relevant to all of them (rare), you are paying for irrelevant contacts and depressing your reply rates.

C-suite fixation

Many B2B marketers default to targeting C-suite because it feels like the right seniority. In reality, C-suite contacts are the hardest to reach, have the highest inbox competition, and often are not the working decision-maker for mid-market contracts. A CFO who might sign a £15,000-per-year invoice finance contract is rarely the person who evaluated three vendors and made the recommendation. That was probably the Finance Manager or Head of Finance. Target the recommender first; they will bring in the signatory.

Buying committees and multi-cell campaigns

For most B2B products with an average contract value above £5,000 per year, the purchase involves more than one person. Gartner research on enterprise buying has consistently found that B2B buying committees in the US average six to ten people. UK mid-market figures are lower (typically three to five), but the principle holds: a single-cell campaign is structurally incomplete.

A practical buying-committee map for a mid-market HRMS platform at a 150-person UK firm might look like this:

• HR Director: primary sponsor, owns the problem, likely initiates the purchase.
• IT Director: technical evaluation, security review, integration requirements.
• Finance Director: budget approval, contract terms.
• HR Manager: end-user requirements, data migration, configuration input.
• MD or CEO: final sign-off on capex above a threshold (say, £30,000 per year).

A multi-cell campaign targets all five roles simultaneously, with a different message for each. The HR Director receives positioning around solving the HR problem. The IT Director receives a security and integration brief. The Finance Director receives a total-cost-of-ownership argument. Running five coordinated touches is more complex than a single blast, but it dramatically improves the probability of at least one committee member engaging.

Authority vs influence: why the highest-seniority contact is not always the right one

Authority and influence are related but not identical. Authority is the formal power to approve a purchase. Influence is the ability to shape the decision before it reaches the approval stage.

Consider a Head of IT at a 200-person professional services firm. They do not have signing authority for a £25,000 IT infrastructure contract: that sits with the IT Director or CFO. But they wrote the requirements document, evaluated two of the three vendors, and recommended one of them. Their recommendation carries enormous weight. Target only the IT Director and you miss the person who controlled the evaluation.

This is why the "Head of" band is undervalued in many campaigns. It sits below Director in the authority hierarchy, but above Manager in influence for most mid-market product categories. The people in these roles are also more reachable: they read their own email, they attend industry events, and they have not yet developed the reflexive cold-email filters that many senior Directors and C-suite contacts rely on.

When building your cell selection, map authority and influence separately. Ask: who signs the contract? (Authority.) Who recommends the vendor? (Influence.) Who identifies the problem in the first place? (Initiator.) These three roles are often three different people in three different cells.

How to map your product to the right cells

Start with three questions before you select any cells:

1. Where does the pain live? Which function feels the problem your product solves day to day? This is usually your primary function target.
2. Where does the budget sit? Which function controls the spend category your product falls into? This is your finance or authority target.
3. Who has signed contracts like this before? Look at your existing customer base and ask where the initial contact came from. If 70% of your deals were initiated by a Head of IT conversation, that cell is your primary.

Take a field-service management platform as an example. The pain lives in Operations (scheduling, dispatch, job management). The budget may sit with the Operations Director or, for larger contracts, the CFO. The person who previously bought similar tools is probably the Head of Operations or Operations Director. Your primary cells are therefore: Head of Operations, Operations Director, and Finance Director as a committee member. Secondary cells might include Head of IT (integration sign-off) and MD/CEO for firms below 100 staff.

For a firm selling B2B data for prospecting purposes, the primary cells are typically Sales Director and Head of Sales (they own the prospecting problem), with Marketing Director as a secondary cell (they may control the data budget) and Finance Director appearing in any procurement process above a low threshold. Knowing this, you would structure a campaign as a three-cell primary effort with a fourth committee cell added for high-value prospects.

For guidance on the legitimate-interests compliance framework that governs outreach to these contacts, see our article on legitimate interests as the lawful basis for B2B data under UK GDPR.

B2B vs B2C role data: why the comparison breaks down

B2B targeting by function and seniority has no direct equivalent in B2C data. Consumer data is segmented by demographics (age, gender, household composition), financial profile (income band, credit indicators), geography (postcode, region), and behavioural or interest data (lifestyle questionnaires, purchase history). The concepts of "function" and "seniority" simply do not apply to a consumer audience.

The practical implication is that the same individual appears in two entirely different data universes depending on context. A Finance Director at a 100-person Bristol logistics company is a B2B contact reachable via legitimate-interests outreach to their business email. The same person, as a consumer, might appear in a fully opt-in consumer file under UK GDPR and PECR consent, reachable for consumer financial products at their home address. These are different records, different lawful bases, and different suppression requirements.

B2B job-function and seniority data is compiled under legitimate interests from public sources, including Companies House filings, corporate websites, public job listings, and industry directories. It does not require the individual's consent, but it does require a Legitimate Interests Assessment and a clear right-to-opt-out mechanism. The B2C consumer file, by contrast, is fully opt-in. Mixing the two frameworks is a compliance error: you cannot use a legitimate-interests B2B record to market a consumer product, and you cannot treat opt-in consumer consent as though it covers B2B corporate outreach.
