Prompt
Help us work on product update emails according to the goals and materials below. [input] Goals and usage situations: I want to clear a block in my product update emails and decide my next course of action. Resources to review: Update history and target users Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Organize changes, impacts, usage methods, and required actions in order of priority. [Results to be created this time] Compare the initial goal and actual results and share good choices, stuck points, and lack of evidence. Instead of criticizing the judgment at the time based solely on the results, choose no more than two hypotheses to change. Please suggest indicators to maintain, change, and observe in the next attempt. [Working Principle] Write according to the actual conditions of your readers and channel. Do not include unfounded figures, reviews, time reduction, or performance guarantees for hooking. Compare product policies with materials provided. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Make sure you have concrete data to compare improvements to in the next attempt. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
