A Solo Newsletter That Reached $15K/mo in 5 Months

How an ex-journalist built a $15K/mo paid newsletter in five months with beehiiv, ChatGPT, and SparkToro.

The Starting Point

Sam T. was a Ex-journalist in Brooklyn, NY running a Paid newsletter business. Sam could write but didn’t know how to grow or monetize a list without a publisher behind him.

“The hard part was never writing. It was knowing who I was writing to.”

What Tools Did They Use?

• beehiiv: Newsletter publishing and ads (Freemium)
• chatgpt: Drafting and research ($20/mo)
• canva: Visuals and logos (Freemium)
• sparktoro: Audience research ($39/mo)

How It Played Out

Month 1: Launched on beehiiv’s free tier; SparkToro found where his readers hung out.

Month 2: ChatGPT cut draft time 50%; a paid tier opened at 5K subscribers.

Month 3-5: Ad network plus paid subs pushed revenue to $15K/mo at 80% margin.

What Were the Results?

• Monthly revenue: $15K/mo
• Profit margin: 80%
• Time to first sale: 30 days
• Email subscribers: 22,000
• Store rating: n/a

Key Takeaways

• A newsletter is a business, not a hobby, from day one.
• Audience research before content saves months of shouting into the void.
• AI is a co-writer, not a replacement for a point of view.
