What you need
- Computer
- Reliable internet
- Newsletter platform account (many have free tiers up to a subscriber limit)

Skills that help: Writing and editing, Marketing, Sales.
Time: A weekly issue on a topic you already follow can fit around a job; consistency matters more than volume.
Typical customer: Readers with a specific professional or hobby interest; sponsors who want to reach that audience
How it makes money: Paid subscriptions, sponsorships and ads, or selling related products and services to readers
Business model: Online business, Side hustle
Risks and downsides
- Audience growth is usually slow; many newsletters never reach a size sponsors will pay for.
- Burnout from keeping a regular publishing schedule.
- Platform price or policy changes, and email deliverability problems, can hurt reach.
- Undisclosed sponsorships or affiliate links can break FTC rules and reader trust.
- Narrow topics can lose relevance if the underlying field changes.
Your first step
Publish four free issues on a free platform tier and share them with people in your niche; track signups and replies before spending on anything.
Then
- Write a one-sentence promise of who the newsletter is for and what they get.
- Read the CAN-SPAM compliance guide.
- Ask early readers what they would pay for.
- Only approach sponsors once you can show consistent open rates and a clear audience.
