Before a real prospect sees your cold email, ad or offer, have Claude play 50 different customers and read every version blind. Works in Claude or ChatGPT.
The prompt
Play 50 different owners of [your customer]. Mix these traits: [trade, size, how they get leads, how they feel about tech]. For each owner, read these versions in a shuffled order without knowing which is which. Score each 1 to 5 for how likely you are to reply, give your honest first thought, what you'd reply, and what stops you. Then count replies per version and group the objections.
[paste your versions]
The trait mix I used
Trade: roofing, landscaping, remodeling
Crew: owner and a helper, up to 40 people
Leads: answers the phone between jobs, a spouse handles calls, Jobber, Angi, word of mouth
Tech: hates software, up to early adopter
Inbox: 5 sales emails a day, or 30 and deletes most
What it told me
Three openers, same offer. The best got 22 replies out of 50, the worst got 12. The biggest objection was "not my problem right now", and the most common question back was "what does it actually say, does it sound like a robot?"
How to read it
Simulated owners are far too nice. 22 out of 50 would never happen for real, so ignore the percentages. Read the ranking and the reasons people would delete it.
