"Personalizing each message one by one is the ideal, but I can't hand-write 500 of them" — AI from 2024 onward tore that wall down completely. This article uses real examples to show when to use general-purpose AI (ChatGPT / Claude) versus a specialized AI (bacotto's sales-copy generator).

The three levels of AI sales copy

01
Level 1: template substitution (the classic approach)
Just string-substitution of "{company}" and "{industry}". Zero personalization feel — the recipient can tell.
02
Level 2: prompting a general-purpose AI (ChatGPT, etc.) each time
Write a prompt and generate one at a time. The quality is high, but it's not realistic for 500 records.
03
Level 3: list-linked AI generation (bacotto's approach)
The AI reads each record's data (category, address, review count, Instagram follower count, etc.) and auto-generates one message per record.

1. How to generate sales copy with ChatGPT

A base prompt

"You are a B2B sales expert. Read the following business information and write one short sales message (under 200 characters) for an Instagram DM." + the business information

ChatGPT (GPT-4o-mini, Claude, etc.) produces copy of sufficient quality. But you have to feed in a prompt one record at a time, which isn't realistic for a 500-record list.

2. bacotto's AI sales-copy generator

The AI reads each record's data and auto-generates one message at a time. It takes about 0.8 seconds per record — roughly 7 minutes for 500.

Hi Atelier Lumi,

Sorry to reach out unannounced.

I've been looking at @atelier_lumi's cut photos and was drawn in

by how you bring in light and your interior.

We provide a way to manage inquiries from DMs and Instagram

all in one place through LINE.

Mind if I send over a doc that takes 3 minutes to read?

Subject[Torigen] A no-show seat costs ¥15,000 — are you guarding against it?

To the team at Torigen,

Hello, and apologies for the unsolicited email.

At a counter-seat restaurant, we often hear that a single no-show

at 7pm wipes out ¥15,000 in revenue.

We've put the steps for absorbing that lost seat with nothing but

LINE Official into a 3-minute video.

SubjectWe analyzed the repeat rates of 12 clinics in Minato-ku

Hi Salon ZEN,

Apologies for the unsolicited email.

Analyzing the repeat behavior of 12 osteopathic clinics in Minato-ku,

we found a tendency for 60% of the top clinics (200+ reviews)

to lose clients at the "second-visit booking" path.

We've put the moves of 3 clinics that lifted their rebooking rate

1.6x into a PDF (10 pages, free).

If you'd like it, just reply with one line.

The same product, pitched from completely different angles depending on the industry. This is what "auto-generated but with no template feel" actually looks like.
