✍️ why rented audiences wreck your marketing plans

Some marketers still have nightmares from the Great Google de-Cookie-ing of a couple years ago.

Others still bear scars from TikTok algo updates that wrecked their social strategies.

Because borrowed audiences are risky. 

That’s why newsletters are our fave. 

You need the borrowed channels for visibility. But owned is where B2B marketers can seal the deal. 

We’ve spent the last year helping clients build newsletters hitting 53–60% open rates, and a few patterns keep showing up: smaller lists outperform bigger ones, voice matters more than polish, and when you treat your newsletter like a product (i.e., obsess over it), it can net big returns.

This week, we’re pulling apart what newsletter giants like Morning Brew, Female Quotient, and ByteSize are doing differently — and why it’s working.

Let’s get into it.

1. Quality of subscriber beats quantity every time

Our co-founder Alex Lieberman put it plainly:

"Quality of subscriber > quantity of subscribers. It will always, always, always make sense to have a smaller, more engaged subscriber base."

The Female Quotient lived that out in practice.

They wanted to build an enthusiastic subscriber base, not a “grandfathered” one, so they started from zero. Eight months later, they hit well above benchmark open rates (and we mean well above) — and as of this writing, just crossed the 100K subscriber mark.

ByteSize took the opposite path.

They inherited a 246K-person list, then intentionally shrank it through a re-engagement flow that removed inactive subscribers. The list dropped from 246,088 to 189,603 engaged readers.

Painful? Yes.

Better for deliverability and long-term engagement? Also yes.

The takeaway: a smaller audience that genuinely wants you in their inbox will outperform a bloated list every time.

2. Voice, voice, voice. Did we mention voice? 

Morning Brew (heard of ‘em?) became recognizable by systematizing voice.

Their framework was surprisingly simple:

• Build a clear persona

• Pick 3 defining personality traits

• Teach writers what's on-voice vs. off-voice

Morning Brew famously wrote for "Stephen" — a hyper-specific reader persona with a midtown commute, a Planet Money habit, and a fear of sounding uninformed in front of his boss on Monday morning. Sound like someone you know? That’s the point. 

When your newsletter voice has actual cultural fluency, readers feel it. They can tell right away whether you actually understand their world.

Specificity is what keeps voice from turning into corporate Mad Libs.

ByteSize nailed this with IT professionals by balancing technical depth with conversational references that felt native to the audience. Think less "enterprise solutions leverage synergy" and more "hey, remember when Pogs were a thing?"

One Female Quotient reader put it perfectly: "I subscribe to many newsletters and 99% of them I delete. I just read your newsletter and know with 100% assurance that I'll be reading all of them moving forward."

These newsletters aren’t worried about “sounding professional.” The internet is full of technically "good" professional content that no one remembers 5 minutes later.

They have a voice. One that sounds like a real person who actually works in their industry and has opinions worth stealing.

3. Build your newsletter like a product, not a marketing channel

The strongest newsletters stop behaving like "content support" pretty quickly.

Their newsletter feeds partnerships, social distribution, executive content, sponsorships, events, and pipeline generation.

Instead of a “marketing send,” it’s an infrastructure. 

(We have a great deeper dive on this exact shift here.)

4. Your readers are telling you what to write

One of the smartest things Female Quotient built was its "Tell Me More" framework: When a topic overperformed on Instagram or sparked unusually strong engagement, they expanded it into long-form newsletter content.

In other words: Social wasn't just distribution. It was a signal detection operation.

The best newsletter teams pay obsessive attention to what gets replies, what gets forwarded, what people screenshot, what subject lines overperform, and what readers bring up weeks later in conversation.

Let’s not pretend our readers are drinking in every word we write. Most of them are skimming between meetings, half-awake, or standing in line for coffee. (Yes, Jessica, we’re talking to you.) 

Attention is rare, and gold. When you have it, you should chase it. 

ByteSize did this. Engagement data pushed the team from bi-weekly to weekly publishing. They put humor and cultural references front and center because readers consistently responded to them.

Your audience will tell you what they like, and strong newsletter operators listen and create based on that feedback. 

Then, they amplify it everywhere:

• Newsletter

• Executive LinkedIn

• Sales enablement

• Events

• Partnerships

• Referral loops

(We’ve covered this from a few different angles lately. Worth a scroll if newsletters are part of your world.)

Campaigns that got us talking: The hottest swag in tech right now is … a spoon. Courtesy of Granola, which is very much not a breakfast cereal company. Let this be a reminder to us all to have a little fun with our marketing, and also really good taste in spoon design.

AI spotlight: Forrester’s take on the AI CMO is worth the read. TL;DR: the future CMO looks a lot more like a Chief Growth Officer.

Stuff that makes us scroll back up: The old SEO trick was writing for algorithms. The new trick is writing clearly enough that AI can confidently steal your answer.

A lot of teams know they should have a newsletter. They’ve got the list. The ideas. Maybe even a half-built beehiiv account collecting dust somewhere. What they don’t have is the time, systems, or editorial muscle to turn it into something people actually look forward to opening.

Which is why we launched our Essentials tier.

Essentials is our newsletter-first offering for lean B2B marketing teams that want consistent strategy, sharp writing, and an editorial engine that actually sounds like a human being wrote it.

Our latest AI ick — and believe us, there are many — is using AI to write emails, then paying another AI to add typos so people think a human wrote them.

AI is making it easier than ever to generate polished marketing. At the exact same time, it’s making human perspective, editorial taste, and identifiable voice more valuable.

The internet doesn’t need more technically “good” content.

It needs more recognizable people.

Which is why the newsletters winning right now are the ones that sound like someone you’d actually want to hear from again next week.

See you then?

Oh! And another thing... 

Fun fact: "swag" originally meant stolen loot. Pirates had it first. Marketers took it. Nobody's surprised. Arrrr!
