This week on Audience Bridge Insights, I sat down with Nathan May, founder of The Feed Media, the largest agency focused specifically on growing newsletter brands.
And let me say this upfront:
If you're still optimizing for cheap leads instead of valuable readers, you're building a list that looks good and performs terribly.
Nathan and I went deep on what's actually working right now in paid acquisition, why Facebook still dominates newsletter growth, and the biggest mistakes publishers make once they start scaling.
Here's the story that stopped me cold.
You can watch the entire podcast now or scroll down to get my insights.
One of Nathan's clients was stuck.
Their cost per lead was low. Their list was growing. But revenue wasn't moving.
So Nathan did something most growth marketers would never recommend:
He increased their cost per lead by 30%.
And revenue went up 10x.
How?
They stopped training Facebook to find "anyone who would sign up."
And started training it to find "people who would actually engage."
Before the change, they were telling Facebook:
"Get me signups"
"Keep the cost low"
"More volume = better"
After the change:
"Get me people who open emails"
"Get me people who click"
"Get me people who buy"
The algorithm did exactly what they asked.
When you optimize for signups, you get signups.
When you optimize for engagement, you get engaged readers.
The cost per lead went up. But the value per subscriber went up 10x.
That's not a growth hack. That's understanding how to build a real business.
That’s why our Smart Leads at Audience Bridge are only tied to subscribers who actually click inside emails.
Why Cost Per Lead Is Lying to You
This is the trap most publishers fall into:
They obsess over CPL.
$2 per subscriber sounds better than $3 per subscriber, right?
Wrong.
If the $2 subscriber never opens your emails and the $3 subscriber clicks, buys, and stays subscribed for a year, you just paid 33% less for 10x the value.
Nathan sees this constantly:
Similar CPL across different sources
Similar open rates on the surface
10x difference in sponsor clicks and buyer behavior
The cheap traffic sources (co-reg, boosts, traffic exchanges) look great upfront.
Then you realize:
They don't click sponsor links
They don't buy products
They churn in 60 days
They quietly destroy your sender reputation
You didn't save money. You wasted it.
This is what Audience Bridge is solving for newsletter publishers by providing insights by source and cohort to understand what the real costs are for generating engaged subscribers.
Creative Is the New Targeting (And Most Publishers Don't Get This Yet)
Here's what changed in the last few years:
The old Facebook playbook was all about interests, demographics, and micro-targeting.
That era is over.
Today, Facebook learns from your creative.
Your ads teach the algorithm who your reader actually is.
The winning strategy now:
Hyper-specific creatives (speak to one type of reader)
Solve one clear problem (not "everyone who likes business")
Let the creative do the targeting (the algorithm will find your people)
If your ad could apply to "everyone," it will convert no one.
Nathan's advice: "Stop trying to be clever. Be specific."
Don't say: "Get smarter about business"
Say: "B2B founders, stop losing deals because your follow-up emails suck"
The second one converts. The first one gets ignored.
Deliverability Is the Silent Killer (And No One Talks About It Until It's Too Late)
One of my favorite parts of the conversation was around deliverability, because almost no one wants to talk about it until it's already broken.
I dropped the truth bomb about open rates with Nathan:
Not all 40% open rates are created equal.
A list where everyone opens sometimes will always outperform a list where half the list never opens.
Zombie subscribers don't just sit there doing nothing.
They actively hurt inbox placement.
If you're still blasting your full list "for the sponsors," you're playing with fire.
Because here's what happens:
You send to 100K subscribers
50K never engage
Gmail sees you sending to unengaged users
Your sender reputation drops
Now the 50K who do want your emails aren't getting them either
You destroyed your reach trying to inflate your numbers.
With Smart Delivery, that we built into Audience Bridge, you get an inside look at performance by ISP (Gmail, Yahoo, Microsoft, etc.) to keep an eye on any issues that may be occurring before it’s to late.
What Smart Operators Are Doing Differently
The best publishers Nathan works with don't just grow lists.
They grow valuable audiences.
Here's what they do:
Track revenue per engaged reader (not revenue per subscriber)
Segment aggressively (don't send to everyone every time)
Stack LTV with products, services, or education (not just ads)
Use paid acquisition only after inboxing is stable (fix the foundation first)
As Nathan put it:
"The fastest way to crush competitors is to increase subscriber value, then outbid everyone."
If your average subscriber generates $10/year and your competitor's generates $2/year, you can pay 5x more for acquisition and still win.
That's the moat.
The Part That Hit Me Hardest
Near the end of our conversation, Nathan said something that really stuck:
"Most publishers are solving the wrong problem. They think their problem is 'how do I grow faster?' when their actual problem is 'how do I make each subscriber worth more?'"
That reframe changes everything.
Because if you solve the value problem first, the growth problem becomes easy.
You can outbid competitors. You can afford better acquisition sources. You can build a real business instead of a vanity metric.
But if you solve growth first and ignore value, you just build a bigger problem.

Want to know if you're optimizing for the right metrics?
We'll look at your acquisition sources, engagement metrics, and revenue per subscriber and show you exactly where you're leaving money on the table and how you can leverage Audience Bridge to scale your list the smart way.
(If you're spending on subscriber acquisition but revenue isn't scaling proportionally, you need this call.)
Let’s acquire those engaged subscribers,

PS: That newsletter Nathan helped? They didn't just 10x revenue by increasing CPL. They built a business that could actually sell because the unit economics finally made sense. Cheap subscribers build cheap businesses.
