IMPLEMENTATION TIPS
- 1
Build a 'newsletter memory': include the last 3 issue summaries and open-rate data in the prompt — the model avoids repeating topics and can reference prior issues naturally.
- 2
Generate 5 subject line variants for every issue and score them for curiosity, clarity, and urgency — the best-performing subject lines often differ dramatically from the obvious first choice.
- 3
Ask the model to write the 'preview text' (the 80-character snippet after the subject) separately — it is often overlooked but contributes significantly to open rates.
