Subject line options
Eight subject lines built on different angles, each with the promise it makes and what the body must then deliver.
The prompt
Give me eight subject lines. Message: WHAT IT IS ABOUT. Reader: WHO THEY ARE and what they already know. What I want them to do: ACTION. Use eight different angles, not eight rewordings of one. Across the set, cover at least: the direct statement, the specific fact, the question, the deadline, the consequence of ignoring it, and the plain label with no persuasion in it at all. For each line give me three things on one row. The line, with its character count. The promise. What the reader now expects to find inside. Delivers or overpromises. Given what I told you the message contains, say whether the body can keep that promise. Overpromising is a specific finding, not a style note, so name it when you see it. Then one line: which option you would pick for this reader, and the single reason why. No emoji. No colon and dash construction on every line. No word that would be read as marketing by someone who reads mostly internal mail. MESSAGE SUMMARY:
How to use it
Run this in Chat. It is a thinking tool, not a deliverable.
Use when the message is written and the subject line is the part still costing you ten minutes.
Vibe prepares and drafts. You verify and decide. Ask for a citation on every finding: a confident answer is not evidence.
What you get back
Eight options across distinct angles, each with its implied promise, plus the ones that overpromise named.
What it writes
Nothing. This one only answers.
