Why your emails get filed with the coupons

Gmail sorts mail by how it looks before anyone reads it. A typical small-business email sends five or six "this is an ad" signals at once.

Knowing what's wrong is the easy part

You've probably heard that simpler emails do better. Then you sit down to write one and hit the real questions:

How do I announce a sale without it reading like an ad?A section on selling without sounding like an ad, plus sale and last-chance frameworks.
What do I send every week?Two newsletter formats you can repeat forever: one that teaches, one that recommends.
What about people who signed up and never bought, or stopped opening?A framework for each, including one that cleans dead weight off your list.
How do I make it sound like my brand, not a template?An AI prompt that adapts every framework to your product and the way you write.
How do I know if it's working?A free 15-minute test that shows which tab your emails land in.
How do I get into Primary and stay there?The one line to put in your welcome email, and the reply habit that keeps you there.

The 10 email frameworks

The emails nearly every small business needs, each with the structure that works, two subject lines, preview text, and notes on what to tell the AI to make it yours.

The "make it yours" AI prompt

Paste in a framework and a past email, and ChatGPT or Claude drafts it in your voice while keeping the rules that matter.

Why I made this

I'm Jeff. I run Sol Book Box, a Spanish children's book subscription, and spent 20 years running an agency before that. When we moved our newsletter to the approach in this kit, our open rates climbed well past what we'd seen before. Here's where it stands today:

~10,000parents on the newsletter
50%+typical campaign open rate
99.9%of emails delivered

Spam complaints are close to zero. I wrote this kit so other small businesses can use the same approach without figuring it out from scratch.

This is for you if

  • You run a small business, shop, or creator newsletter
  • You send your own emails from a standard email platform
  • Your open rates feel lower than they should be

It's not for you if

  • You need technical deliverability work (DNS records, domain warm-up, sending infrastructure)
  • Your brand depends on heavily designed, image-led emails

Questions

Will this guarantee my emails land in Primary?

No one can promise that. Gmail doesn't publish its rules, and a sale email will sometimes land in Promotions no matter what. This kit gives your everyday emails a much better chance, and shows you how to test where yours land.

Does it work with my email platform?

Yes. The format is about how you write, not which tool you use. It works with MailerLite, Mailchimp, Klaviyo, Kit, Flodesk, and others.

Do I need to be technical?

No. If you can write an email, you can use everything in the kit.

Do I need an AI tool?

No. You can fill in each framework yourself. The prompt is there to save time, and works with the free versions of ChatGPT and Claude.

What format is it?

An 18-page PDF you can download right after purchase.
