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.
