When should a event organiser hire an interim head of marketing?
Consider interim event marketing leadership when you need someone to make decisions, set priorities and direct delivery for a defined period. If the strategy is clear and the main problem is unfinished work, delivery support may be a better fit. Diagnose the missing responsibility before choosing the job title.
A team can be busy and still lack leadership. Campaigns may be going out while nobody is connecting audience acquisition, sponsor activity, reporting and the event’s commercial priorities.
That is a different gap from needing an extra campaign manager.

Which situations justify interim marketing leadership?
Use these situations as prompts for discussion, not an automatic prescription:
A leadership vacancy: someone needs to own decisions while you recruit or manage an absence.
A launch or transition: the team needs a clear approach and coordinated delivery for a defined phase.
A performance problem: you need senior diagnosis before committing to more activity.
A portfolio conflict: overlapping events need agreed priorities and resource decisions.
A capability transition: the team needs leadership while responsibilities or ways of working change.
Before engaging anyone, test whether they will have the authority and access needed to address the problem. Hiring a senior title without decision rights leaves the underlying gap intact.
What should the role own?
Define the remit around decisions and outcomes, not a long list of channels. An interim leader’s scope might include reviewing the campaign plan, setting priorities, directing internal and external resource, and establishing a useful performance review.
Agree what remains with the event director, sales team, permanent marketing team and other suppliers. Make responsibility for budgets, approvals and campaign changes explicit.
Do not assume one person will also deliver every email, write every asset and manage every advertising campaign. List the hands-on work separately and confirm who will do it.
What is the difference between interim and fractional support?
Use “interim” to describe the temporary leadership requirement and “fractional” to discuss a part-time allocation of senior capacity. The terms can overlap: a temporary leadership engagement may be part-time. Providers use these labels differently, so agree the actual days, remit, access and duration rather than buying a label.
CDM’s model combines a senior strategic consultant with a flexible contractor delivery team. Its published offer covers B2B exhibitions, conferences and senior-audience events, with resource shaped around gaps in the organiser’s team. Ask whether that combined model fits your situation or whether a narrower engagement would be sufficient.
What should you include in the brief?
The event or portfolio, key dates and commercial objectives.
The reason you need support and the decisions currently lacking an owner.
The existing team, suppliers and responsibilities.
Current campaign plans, performance information and known measurement gaps.
The available budget, decision-making authority and approval process.
The proposed engagement period and what a successful handover would look like.
Ask candidates or providers to explain how they would establish priorities with incomplete information. A credible discussion should cover what they need to inspect before recommending a solution, not promise an uplift before seeing the starting point.
How should you judge whether the engagement is working?
Agree a baseline and the measures relevant to the remit. These might include qualified registrations, paid bookings, sponsor pipeline or rebooking progress where the role can influence them. Define each measure and its reporting source; avoid treating different registration types or pipeline stages as interchangeable.
Also check the operating improvements: clearer ownership, fewer unresolved decisions, realistic priorities and documented campaign knowledge. Commercial outcomes have multiple contributors, so distinguish the leader’s responsibilities from factors outside their control.
Plan the exit from the start. The handover should leave the next owner with decisions, assets, reporting definitions and outstanding priorities—not just a presentation summarising what happened.
