## How to Automate Newsletter Writing — Step-by-Step

1. **Curate sources**: Feedly/Readwise pulls from 30–50 trusted sites 2. **AI summarize**: assisters.dev distills top 10 stories of the week 3. **Draft intro**: AI writes in your voice from a 500-word prompt with samples 4. **Human edit**: 30-min pass for voice + commentary 5. **Schedule**: Beehiiv/Substack for optimal send time 6. **Segment**: engaged subscribers get longer version; cold get shorter 7. **Analyze**: AI reviews last 4 issues, suggests format tweaks

## FAQs

**Can AI write my newsletter voice?** With 3–5 past issues as samples, 70% of draft matches voice; human edits rest.

**What's the best send time?** Saturday 8–10am or Sunday 7–9am; test with your audience.

**Should I monetize?** Free first until 2K engaged; paid tier at 5K+ makes sense.

**How long should issues be?** 500–1500 words is sweet spot; depends on audience.

**Do I need my own domain?** For long-term brand yes; start on Substack/Beehiiv subdomain is fine.

## Conclusion

Newsletters are the highest-leverage direct audience asset in 2026. Automate the curation and drafting, keep human voice in the intro, and ship every week without fail.
