The 3 newsletter archetypes:
Curated — Links + commentary (e.g., TLDR, Morning Brew)
Original — Single essay/article (e.g., Lenny's Newsletter, Stratechery)
Hybrid — Original intro + curated links (most common)
| Frequency | Pros | Cons | Best For |
|---|---|---|---|
| Daily | Habit-forming, high touch | Burnout risk, high churn | News, curated |
| 2-3x/week | Good balance | Moderate effort | Curated, hybrid |
| Weekly | Most sustainable | Slower growth | Original, hybrid |
| Biweekly | Low effort | Easy to forget | Premium, long-form |
| Monthly | Minimal time | Low engagement | Company updates |
Recommendation: Start weekly. Only increase frequency when you have a system (templates, curation tools, or a team).
