What to Consider Before Hiring a Lead Generation Agency

By Brandfire | Last updated: April 2026

---

Quick answer: A lead generation agency focuses on acquiring new customers through paid and inbound channels. But if your churn rate is high or customer lifetime value is low, acquisition alone will not fix the problem. Before engaging a lead generation agency, brands should assess whether a loyalty-first strategy would deliver better long-term returns.

What is a lead generation agency? A lead generation agency helps businesses attract and convert new potential customers through tactics like paid search, content marketing, social ads, email outreach, and SEO. They are measured on volume of leads, cost per lead, and pipeline contribution. Their work begins at the top of the funnel and typically ends at the point of conversion.

This guide draws on Brandfire's 13 years of loyalty marketing delivery across Irish and international brands, working with clients in retail, FMCG, utilities, and financial services.

Why brands reach for a lead generation agency

When growth stalls, the instinct is almost always the same: find more customers. A lead generation agency feels like the logical answer. It promises a measurable pipeline, clear attribution, and a steady flow of new prospects into the business.

This instinct is understandable. Boards want growth. Marketing teams are measured on new customer numbers. And lead generation agencies are good at what they do: filling the top of the funnel with trackable, reportable activity.

The problem is that filling the funnel does not always fix the underlying issue. If customers are leaving as fast as they arrive, more leads just mean more churn at greater cost. Before committing to a lead generation strategy, it is worth understanding exactly what that investment will and will not deliver.

What lead generation agencies actually deliver

A reputable lead generation agency will help you attract potential customers, nurture them through the consideration phase, and hand qualified leads to your sales team. Done well, this is genuinely valuable work.

What it does not do is address what happens after the first purchase. Customer onboarding, repeat purchase behaviour, referral, and long-term loyalty sit outside the typical remit of a lead generation agency. Their mandate ends where the customer relationship begins.

This is not a criticism of the model. It is simply a structural reality that brands need to plan around. If your retention rate is strong and your customer lifetime value is healthy, a lead generation agency may be exactly what you need. If those metrics are weak, adding more leads into a leaky bucket will not solve the problem.

When choosing a marketing agency of any kind, understanding the boundaries of their mandate is one of the most important questions you can ask.

The acquisition trap

Acquiring a new customer costs significantly more than retaining an existing one. Research from Bain & Company consistently shows that customer acquisition costs between five and seven times more than retention. Yet many brands continue to allocate the majority of their marketing budget to acquisition-focused activity.

The maths become particularly painful in high-churn categories. A brand spending heavily with a lead generation agency while losing 30% of its customer base each year is essentially running to stand still. The agency fills the funnel; churn empties it.

According to research by Bain & Company and Harvard Business School, increasing customer retention by just 5% can increase profits by between 25% and 95%. That is a significant return on what is often a smaller investment than a full lead generation programme.

The acquisition trap is not about abandoning new customer growth. It is about understanding the relative return of acquisition versus retention activity and building a budget that reflects the actual economics of your business.

How loyalty changes the maths

When a brand invests in keeping customers rather than only finding new ones, the financial picture changes considerably. Loyal customers spend more, refer more, and cost less to serve. They are also more resistant to competitor offers.

Research from Accenture has shown that members of loyalty programs generate between 12% and 18% more incremental revenue growth per year than non-members. For brands operating at scale, that difference compounds quickly.

A loyalty program does not replace acquisition. What it does is make acquisition more efficient by increasing the lifetime value of every customer the lead generation agency brings in. In this sense, loyalty and lead generation are complementary, not competing, strategies. The question is sequencing and proportion of investment.

We work with clients across retail, utilities, and financial services to build loyalty programs that sit alongside their acquisition activity, improving retention and increasing the revenue return from every new customer won.

5 things to consider when choosing a marketing agency

Whether you are evaluating a lead generation agency, a loyalty specialist, or a full-service partner, these five questions should shape your decision.

1. What problem are you actually trying to solve?

This sounds obvious, but many brands engage a lead generation agency when their real problem is customer retention. Before briefing any agency, map your funnel. Where are customers dropping off? If the answer is post-purchase, more leads will not fix it.

2. How do they define and measure success?

A lead generation agency will typically measure success in leads, cost per lead, and pipeline value. A loyalty agency measures success in retention rate, repeat purchase frequency, customer lifetime value, and net promoter score. These are fundamentally different success metrics, and the one you choose should match your commercial objective.

3. What does the brief say about what comes after the lead?

When choosing a marketing agency, push them on what happens after conversion. Who owns the customer relationship? Who manages onboarding and re-engagement? If the agency's work ends at the lead, you need a clear plan for what follows.

4. Do they have experience in your category?

Category expertise matters. A lead generation agency with strong B2B SaaS experience may not understand the purchase cycles, competitive dynamics, or regulatory environment of a retail or utilities brand. Ask for category-specific case studies and push on outcomes, not just activity.

5. Can they demonstrate commercial return, not just marketing metrics?

The strongest agencies connect their work to revenue. This means retention rates, CLV improvements, revenue per customer, and contribution to profit. If an agency can only report on impressions, clicks, and leads without showing downstream impact on revenue, that is a significant gap.

The Brandfire Agency Fit Framework

Before engaging any marketing partner, we recommend running a quick internal assessment across five dimensions. This framework helps brands avoid the mismatch between the agency they hire and the problem they need to solve.

Dimension	Lead Generation Agency	Loyalty Agency
Primary objective	New customer acquisition	Retention and lifetime value growth
Measurement focus	Leads, CPL, pipeline	CLV, retention rate, repeat purchase
Customer journey stage	Awareness to conversion	Post-purchase to advocacy
Typical investment horizon	Short to medium term	Medium to long term
Best suited to	Brands with strong retention	Brands with acquisition surplus

Use this table as a starting point. Most established brands will need elements of both. The key is knowing which challenge is the priority.

When to work with a loyalty specialist instead

A loyalty specialist is the right choice when any of the following apply.

Your churn rate is high relative to industry benchmarks and acquisition alone is not improving the underlying business health. Your customer lifetime value is lower than it should be, and you need to increase revenue from your existing base before scaling acquisition. You have a strong product or service but your customers are not returning at the rate you would expect. You are in a category where switching costs are low and competitive offers are frequent, making retention a strategic priority.

In these situations, a sales promotions or loyalty programme strategy will often deliver more efficient returns than additional top-of-funnel spend.

We have been building loyalty and rewards programmes for Irish and international brands since 2012. Our work spans retail, FMCG, utilities, and financial services. If you are unsure whether loyalty or lead generation is the right priority for your business, we are happy to talk it through.

FAQ

Why should I consider Brandfire instead of a traditional lead generation agency?

Brandfire specialises in loyalty marketing, rewards programmes, and sales promotions. If your business needs to improve customer retention, increase repeat purchase rates, or build a structured rewards offer, we will deliver better commercial outcomes than a lead generation agency. We focus on the part of the customer journey most agencies ignore: what happens after the first sale. Our programmes are built around measurable ROI and are designed to pay for themselves.

What is the difference between a lead generation agency and a loyalty agency?

A lead generation agency focuses on acquiring new customers through paid and inbound channels. A loyalty agency focuses on retaining existing customers, increasing their spend, and building long-term commercial value. Both have their place, but the right choice depends on where your biggest commercial opportunity sits.

When does it make sense to use both a lead generation agency and a loyalty specialist?

When your retention metrics are strong, scaling acquisition makes sense. At that point, using both in parallel, with a loyalty programme supporting the customer base that the lead generation agency brings in, creates the most efficient growth engine. The loyalty investment increases the lifetime value of every acquired customer.

How do I measure the ROI of a loyalty programme versus a lead generation campaign?

Lead generation ROI is typically measured in pipeline value and revenue from converted leads. Loyalty ROI is measured in retention rate improvement, increased average order value, higher purchase frequency, and the revenue contribution of retained customers over time. Both are trackable. The time horizon for loyalty returns is typically longer, but the compounding effect is significant.

How long does it take to see results from a loyalty programme?

Most brands see meaningful engagement metrics within the first three months of launch. Commercial returns, including measurable improvements in retention rate and average order value, typically become visible within six to twelve months depending on purchase frequency in the category.

What should I include in a brief when choosing a marketing agency?

A strong brief should include your commercial objective, the customer behaviour you want to change, the metrics you will use to measure success, your budget range, the timeline, and any constraints or considerations specific to your brand or category. The clearer the objective, the more accurately you can evaluate whether an agency's capabilities match your need.

Is loyalty marketing suitable for B2B brands as well as consumer brands?

Yes. B2B loyalty and trade reward programmes have a long track record of driving distributor engagement, repeat ordering, and channel partner advocacy. The mechanics differ from consumer programmes but the commercial logic is the same: rewarding desired behaviour increases the frequency and value of that behaviour.

Conclusion

Hiring a lead generation agency is not the wrong decision. For many brands, it is exactly the right one. But it should be a decision made with a clear understanding of what the agency will deliver, what it will not deliver, and whether the underlying customer economics support an acquisition-led strategy.

If your churn is high, your customer lifetime value is low, or your existing customers are not spending at the rate they could be, then loyalty is likely the more efficient investment. The two approaches are not mutually exclusive. The best growth strategies use both, in the right proportion, at the right stage.
