GROWTH STRATEGY
An in-depth analysis
My agency helped 10+ financial services firms grow their B2B newsletters. We acquired over 150,000+ combined subscribers. I've seen firsthand what works and what doesn't in financial newsletter marketing..
Let's cut through the noise and look at reali life examples with numbers.
Paid Ads: The Quick but Costly Route
Think of paid ads like renting a luxury office space. You get instant visibility, but the bills keep coming. Here's what our financial clients typically see:
Average cost per lead: $50-75 (among all channels)
Client conversion rate: 2-3%
Real cost per new client: $2,000-3,000
Plus, the moment you stop paying, your leads vanish. It's like turning off the water tap – the flow stops instantly.
Newsletters: The Slower but Smarter Investment
Now, imagine building your own office instead of renting. That's what a newsletter is. Here's what we see with our financial services clients:
Average cost per lead: $5-15 (can be as low as $1 but here a conservative example)
Client conversion rate: 5-8% (higher trust built through valuable content)
Real cost per new client: $200-300

But here's the best part – these numbers keep improving over time.
Why? Because of the value you provide each week.

Real Numbers, Real Results
Here is a real life example with a wealth management firm:
Year 1 with paid ads:
Spent: $120,000
New clients: 45
Cost per client: $2,666
Year 1 with newsletter:
Spent: $24,000
New clients: 52
Cost per client: $461
Why Newsletters Win for Financial Services
Trust Factor
Your clients aren't buying a $20 t-shirt. They're trusting you with their financial future. Newsletters build trust slowly but surely. Every week, you're in their inbox sharing insights. No hard sell needed.
Consumer education is a key factor in this process (Psychology Today)
Longer Shelf Life
One of our banking clients still gets leads from 18 months old newsletter articles. Try getting that from a Facebook ad!
Higher Quality Leads
Newsletter subscribers who become clients stay longer. We see 85% retention rates versus 60% from paid ads.
Compound Effect
Like a good investment, newsletters grow in value. Our asset management clients typically see:
Month 1: 0.5% conversion rate
Month 6: 3% conversion rate
Month 12: 7% conversion rate

The Smart Way to Start
Pick one core topic (like retirement planning or wealth preservation)
Write 1 article per week
Keep them short (800-1200 words, aka less than 10 min read)
Add one clear call to action
Track your open rates and clicks
The Bottom Line
Yes, paid ads can get you clients faster. But newsletters build a lasting asset that gets more valuable over time.
Most of our clients now use both – paid ads for quick wins, newsletters for long-term growth.
But if you had to pick one? Start with newsletters. Especially to build lasting client relationships while keeping costs down.
Think of it this way: Would you rather rent a billboard or build a reputation?
Reputation always wins.
Have a look at this study by Harvard Business Review.
CASE STUDY
“How do I know if my newsletter niche is too niche?”
“The money is in the niches”
We’ve all heard it. And it's true until you take it too far. So when is a niche too niche?
The great thing about B2B is that there are a lot of data out there. To have a rough idea we use a tool called Apollo (not sponsored not affiliated).
You can create and account for free and play around with it. The goal here is to figure out how many people are within your specific niche.
If I’m targeting Italian founders of agricultural small businesses (1-10 employees), I’ve got 8 results.
N.B. we use the filter “Email Status: likely to engage and verified” for a more accurate search
In this case I clearly went too far. We like to niche down to a rough estimate of 20,000 people. That’s plenty to get traction and to eventually grow out of it if we saturated the niche.
