Best Gemini Prompt for “Write an Email Newsletter

Gemini uses a sandwich structure: role and context at the top, task in the middle, and all constraints at the end. Gemini tends to drop constraints that appear early in the prompt, so boundary words like 'only', 'must', and 'strictly' placed at the end are essential. This free template is optimized specifically for Gemini, achieving approximately 37% token reduction compared to unoptimized prompts while producing higher quality output.
