Newsletter

This is a comprehensive playbook for building and growing email newsletters, whether you're starting from zero or scaling past 10K subscribers. It covers the fundamentals (subject line formulas, content archetypes, frequency tradeoffs), growth tactics tier by tier (lead magnets and landing pages early, referral programs and cross-promotions mid-stage, paid acquisition late), and monetization benchmarks (sponsorship CPM rates by niche, when to launch paid tiers). The deliverability section alone is worth it, walking through SPF/DKIM/DMARC setup and spam filter avoidance. It's opinionated in the right ways, like advocating weekly cadence to start and cleaning your list of non-openers every 90 days. If you're launching on Substack or Beehiiv and don't want to figure this out through trial and error, it compresses a lot of expensive lessons into actionable templates.
