Creating Email Marketing Templates with ChatGPT - AI Newsletter Production Guide

Introduction

"Who is our product for?" If you can't answer this clearly, marketing fails. A startup I consulted in the past said "Our product is for everyone." The result? Hundreds of thousands of dollars in ad spend and 0.3% conversion rate...

The problem was vaguely defining the target as just "women in their 20s-30s". Early 20s college students and late 30s working moms are completely different people, but approaching them with the same message meant no one could relate.

Marketing succeeds when it deeply resonates with specific individuals. To do that, you need to paint a specific person. Not just name, age, and job, but their daily routine, worries, and values in detail. This is "persona".

AI can create very sophisticated personas based on the information you provide. Beyond simple demographic information, it specifically depicts that person's lifestyle, digital habits, and purchase journey.

Why Are Personas Important?

Marketing without personas is like throwing darts blindfolded. You don't know where to throw, so you leave it to chance. But with personas, you know exactly where to aim.

With specific targets, everything becomes clear. What message to use (if it's 29-year-old office worker Sujin, "5-minute routine after work"), what channel to use (Sujin uses Instagram a lot), and what tone and manner to use (friendly and relatable tone) all naturally follow.

I've seen a cosmetics brand redefine their personas and triple their conversion rate with the same ad budget. The ad content was almost identical - just more precise targeting. That's how important personas are.

Real Example 1: Creating Basic Persona

My Input:

Main customers are women in their 20s-30s,
but I want to create more specific personas.
