The prompt that produces a good first draft is not the same prompt that produces the output you actually send.
The most consistent quality improvement available to any AI user is iteration: asking Claude to improve, refine, tighten, or change a specific aspect of what it just produced.
The most useful iteration commands
- "Make this more concise by 30%." Almost always improves email and follow-up quality.
- "Rewrite the opening line. The current one is too generic." Single-line improvements compound significantly.
- "The tone is too formal. Rewrite it at a peer-to-peer level." Shifts the register of the entire piece.
- "Remove any passive voice." Forces more direct, confident language.
- "The CTA is too soft. Rewrite it as a specific, time-sensitive ask." Sharpens the close of any email.
- "Version 2: same message, but lead with the customer outcome instead of our solution." Flips the framing entirely.
The rule
Never send the first draft. Run at least one iteration on anything going to a prospect. The discipline of one iteration creates the habit. The habit creates compounding quality improvements that are invisible to anyone watching from the outside but felt by every prospect who reads your emails.
