How to build a six-figure newsletter business from scratch

Executive overview

Most people underestimate what a newsletter can become. Alex Garcia runs five newsletters with 160,000 combined subscribers generating $65–70K/month from sponsorships alone.

The core model: pick a niche you love or one that's exploding, build an audience through hand-to-hand outreach and content marketing, then sell sponsorships once you hit scale.

A newsletter is not just a product — it's top-of-funnel for everything else you want to build.

Finding your niche

• Write about what you already read, research, and love — that's the sustainable path
• Alternatively, find a topic that's exploding right now and build a business around it
• Alex mapped his interest in marketing + HBR-style analysis → Marketing Examine

Getting your first subscribers

• Hand-to-hand combat: DM people on LinkedIn, Twitter, Instagram; tap Facebook friends; run small giveaways
• Do the unscalable things first — adding 10–15 subs at a time still compounds
• Then switch to buffet marketing: test many channels simultaneously, identify what has 10x potential, double down on the one or two that drive growth
• Alex wrote 50 marketing threads over 50 days on Twitter, going from 500 to 40,000 followers and 2,000 to ~9,000 newsletter subs

Content sourcing

• Use content tools (e.g. BuzzSumo-style) to surface the most-shared articles on any topic
• Twitter advanced search surfaces hidden gems and underreported stories in your niche
• Hire niche writers by digging into pages 2–4 of Google search results — strong writers hide there

Growing beyond the early stage

• Content marketing: publish growth-oriented content on Twitter (threads perform best); funnel readers to the newsletter
• Paid acquisition: test Facebook, Instagram, TikTok, Reddit ads; use what works in threads as on-page copy
• Cross-promotions: platforms like SparkLoop and Beehive let you set a monthly budget and piggyback on other newsletters for subscriber growth

Monetising with sponsorships

• Sponsorships are the simplest monetisation: you've built distribution and trust; advertisers want a piece of that
• Frame your newsletter as a targeted ad channel — similar ROI logic to Facebook or TikTok ads
• At 10,000 subscribers you can charge $1,000+ per sponsorship slot
• Inbound: make it easy for readers who want to sponsor to do so directly
• Outbound: find advertisers already spending on newsletters in your niche and reach out directly

Alternative monetisation

• Paid newsletter tier: free newsletter acts as top-of-funnel; paid tier (~$9–11/month) offers exclusive content (see: Lenny's Newsletter)
• Services: use the newsletter as a testing ground for productised services, then convert learnings into a scalable product

Tools to run the operation

Four tools cover the core infrastructure:

1. Zapier — connects everything
2. Notion — controls everything
3. Slack — team communication
4. ESP (email service provider) — sends the emails

Scale and upside

• Morning Brew: sold part of the company for $75M cash, now doing $100M+ revenue
• The Hustle: estimated $20–30M exit from one newsletter plus a paid product
• Newsletters are also top-of-funnel for agencies, courses, communities, or any other business you want to build
