Claude + ChatGPT Just Changed Email Marketing Forever

The Inbox Newsletter

Hey it’s Max from The Inbox Newsletter.

And it’s got some bonuses with it I wanted to give you in this newsletter…

Quick context.

AI is everywhere right now…

And I keep seeing people saying they automated their entire email channel with one prompt.

But I’ve found that most people’s AI output is trash.

Which is why I built two AI resources trained on everything we do across 100+ brands and $250M+ in email data.

In the video I walk through every use case on screen, but here's what you get:

1. Free Email Marketing Brain Custom GPT

This ChatGPT bot can pump out campaign calendars, email copy, flow strategies, and email audits that are all trained on my frameworks.

And it’s free!

2. Custom Claude Email Marketing Skill File

This is the more advanced version and honestly the output is on another level compared to the GPT, especially when it comes to writing copy.

These are the actual skill and context files we give Claude internally at my 100+ client agency.

It forces you to give proper brand context before it writes anything and then QAs against itself to make sure nothing is made up.

This one is only available inside my Skool community alongside 30+ course modules, 250+ templates, and two live calls a week with me.

Watch the full video to see me walk through every use case live on screen. It's about 25 minutes and covers everything A-Z.

Worth a watch if you're using AI at all for email.

Notes:
Really clean and effective email showing the savings you get on subscription. The visualizations of the costs are the cherry on top!
