I'm not naming the operator. They asked me not to and I want them to keep talking to me.

What I will say: it's a B2B newsletter in a verticalised software niche, three issues a week, started August 2024, and as of this month is doing $40,400 MRR off two sponsors and a private community. No author photo. No personal brand. No LinkedIn essays. The voice is a 'we' that points at nobody in particular. They write under a pen name that has its own LinkedIn that has its own posts. The whole thing is a fortress built quietly.

The numbers

  • List size: 38,400 confirmed subscribers as of this month.
  • Open rate: 47% (B2B niche, qualified list).
  • MRR: $40,400 — $28K from two sponsors at $14K/month each, $12.4K from a $39/mo private community.
  • Costs: $890/month all-in (ESP, hosting, one freelancer doing research).
  • Time invested by the operator: 16-18 hours/week.

Net: roughly $39,500 in margin. On 70 hours of work a month. Which works out to $565 an hour. Yes, those are the real numbers. I've seen the screenshots.

How the niche was picked

This is the part everyone skips. The operator spent three weeks before writing a single issue doing one thing: scrolling LinkedIn and Twitter for the niche where mid-level employees were complaining the loudest about not having a good information source. Not the niche where they wanted to read. The niche where they were already actively searching for and not finding what they needed.

That niche turned out to be a vertical I'd describe as 'enterprise procurement adjacent' — specific enough that I won't get more specific than that. The bet: people whose jobs depend on knowing the latest moves will pay attention to anyone who reliably tells them. Sponsors who sell into those people will pay to reach them.

How the list got to 1,000

Cold. The operator spent the first two months writing 30 highly-specific LinkedIn posts about the niche, each one ending with a 'I write a newsletter about this' link. Posted from the pen-name account. Got to 1,400 subscribers in ten weeks before they wrote a single newsletter issue.

Lesson: do not start the newsletter until you have an audience for it. Build the line first. Then ship.

How it got to 10,000

Two things, in order. First: cross-promotions with three adjacent newsletters in the same niche. They split the cost of a SparkLoop campaign for two months and ate the unit economics. Got to 6,800 in five months.

Second: one piece went mildly viral on LinkedIn. A specific industry move broke and they were the only newsletter that called it before the trade press did. Picked up 2,400 new subscribers in 72 hours. Lesson here: the audience-builder is preparation. The breakout is luck. You build the preparation so you can survive the wait for the luck.

How the first sponsor got signed

At 18,000 subscribers the operator wrote a one-page sponsor pitch with three numbers: list size, open rate, audience composition. Sent it cold to the marketing leads at six companies who were already running ads on the cross-promo newsletters. Two replied. One signed at $4,000/month, four issues a month, 90-day commitment. That sponsor is now paying $14,000 a month and has been in the rotation for fourteen months.

Pricing isn't a function of subscriber count. It's a function of audience quality. Don't undersell.

The community add-on

Twelve months in they launched a paid Slack at $39/month. 318 paying members as of this issue. The pitch to subscribers was specific: 'You'll see deals, contacts, and intel I won't put in the newsletter because the people involved would lose their jobs.' That promise has held. The retention is 92% month-over-month, which is wild for a paid community.

What I'd copy and what I wouldn't

Copy: the niche-selection process, the audience-first build, the cold-outbound sponsor sales. Don't copy: the faceless brand, unless your topic actually requires it. Most don't. Most operators tell themselves they want to be faceless because they're scared. The operator I'm writing about is faceless because their day job would fire them. There's a difference.

Frequently asked

What ESP are they using?
Beehiiv. They moved off ConvertKit at 8,000 subscribers because ConvertKit's deliverability on cold-acquired lists was hurting them.
Did they pay for traffic?
Only the SparkLoop cross-promo spend. No paid ads. Their CAC through SparkLoop ran around $2.40/subscriber, which is low for B2B.
Are they hiring?
One freelancer at 8 hours a week doing research. Not full-time. The operator likes the operating leverage too much to add headcount.
