Let your audience show you what’s working—and meet me in our LIVE masterclass

It’s finally here!

Substack just released one of the most powerful features for newsletter creators: A/B testing for subject lines.

This is big.

I have early access to this tool and am happy to present it to you in an easy and smart way in tomorrow’s ⏰LIVE Substack masterclass - to save you time, energy and headaches. You’ll be prepared for when it’ll be rolled out in a few days.

If you’ve ever struggled to figure out which subject line will get more opens (and who hasn’t? 😃 I’m looking at YOU!), now Substack gives you the tools to test and know for sure.

The best: It’s built right into your minimalist Substack post editor:

• Write two or more subject lines

• Substack sends each to a small portion of your list

• The “winner” gets sent to everyone else

Simple.

Powerful.

And honestly—way overdue for me as marketing and brand manager (Thank you, Substack! A KIT-y tool that will definetly lure more writers to get on Substack).

But before you jump in and start testing together with me tomorrow, I want to share a few things I wish someone had told me when I first started experimenting with A/B tests.

What Is A/B Testing, and Why Should You Care?

If this is new to you, let me help you with my 15+ years of marketing expertise (Didn’t know that? Go check out my About to learn more about how I monetize my skills and help you grow together with me.)

A/B testing (also called split testing) is when you try two different versions of something—like a headline or subject line—and see which one performs better.

For example:

• You send “Version A” to one part of your list

• You send “Version B” to another

• You track which one gets more opens or clicks

It’s a great way to let your audience show you what’s working—and what’s not.

But like with anything in marketing, there’s no “right way” to do it (although many would say there is).

But there are some pitfalls to avoid. I’ll share 6 in tomorrow’s ⏰Substack LIVE Class for paid subscribers.

Here’s #4

4. Your list is too small to test (yet)

If you’re just starting out and only have a few subscribers, don’t stress about A/B testing right now.

Just focus on sending valuable content consistently. That’s how you build trust—and when your list grows, you’ll have more room to test and experiment.

A Simple Trick to Create Better Subject Lines To Test

If you’ve ever stared at a blinking cursor thinking,

“What the heck do I write for this headline/subject line?”
…you’re not alone. I’ve been there too.

This tip from a headline training I once attended changed everything for me, and I think it will for you, too.

Make a list of 10–30 subject lines. Yes, even if that feels like overkill.

You’ll soon notice: the first few are usually just okay.

But as you keep going, the good stuff starts to flow.

Once you’ve got your list, narrow it down to your top two, and A/B test those.

Easy.

🎁BONUS 1: Predict the Winner With ChatGPT (Before You Even Send!)

As I know many of you are using AI to send posts on Notes or write their newsletters, I have an AI prompt for you which I’m gonna share in our Substack LIVE for paid subs.

My ChatGPT prompt will give you insights you might have missed—and help you feel more confident before hitting “send.”

🎁BONUS 2: New AI-Fueled Tool to Test Your Subject Lines

Also, I’m gonna share a NEW tool which you can use to create a list of headlines and see which one could perform best before you even start the test so that you let Substack test the best of the best.

My Challenge For You

Whether you’re just getting started or you’ve been in the newsletter game for a while, I don’t care, I want you to try one of these:

• Make a long list of subject lines before or during tomorrow’s session

• Let’s test some of them with the help of Substack, ChatGPT and the new tool I’m gonna show you LIVE

Trust me, A/B testing is simple. It’s smart. And it’s going to help you get more opens and better results with every email.

Also you’ll become a better headline writer.

You’ve got this. I’m cheering you on.
