2. Organize “newsletter” reading time: Block a small window like Monday mornings to skim these. Summarize key insights for your leadership or dev teams.
3. Test & implement: Many newsletters supply quick experiments (like a new upsell tactic). Put them into action and measure changes in open rates, user acquisition, or churn.
4. Unsubscribe if it’s not delivering value: Keep your inbox tidy focus on the 5 or 10 you find most beneficial, and unsubscribe to the rest.
