When a creator with 10+ years of brand equity, 100K+ followers, and 6-7 figures in revenue trusts @coreli.ai with her brand — that's what keeps me going.
I know what that trust costs. I've watched Julia obsess over every detail of hers for 15 years straight. To the creators who've already said yes — thank you. We don't take it lightly.

I’m embarrassed I’m just learning this.
15 years as a creator. 12 years with an email list. I’ve always called myself data-minded. And I never once compared our email numbers to our Instagram numbers side by side.
When I finally did:
→ 50–70% of email subscribers see what we send
→ 8% of Instagram followers see a given post
→ Email is 7–9x more visible per person
→ 16% of email opens convert to clicks; <1% of post views convert to saves or shares
→ In March, email drove the same actions as Instagram with 1/4 the audience
→ @juliaberolzheimer has 1.3M IG followers. A 20K email list drove the same number of actions
The takeaway: there’s no algorithm between you and your subscribers. You own the relationship.
Don’t have an email list? Start one today. Substack, Klaviyo, ConvertKit — pick one.
Already have one? Go pull the numbers. It’s probably the most valuable thing you own.

The creator behind ShopMy’s #1 creator is coming to Creator Method Summit and he’s pulling back the curtain on how influence becomes a real business. 👀
Meet Thomas Berolzheimer, Co-Founder & CEO of Coreli and the commerce strategist behind Julia Berolzheimer’s creator empire.
While most creators are chasing their next viral moment or brand deal, the smartest are building something far more valuable: an audience that doesn’t just watch, but buys. Repeatedly.
At Creator Method Summit, Thomas is joining us for an exclusive conversation on the business of affiliate marketing, including the storefront strategies, conversion psychology, and revenue systems that turn personal influence into long-term commercial value.
We’re talking about what actually makes people buy, how to build a commerce ecosystem around your personal brand, and what separates creators who generate views from those who generate revenue.
This is the kind of insider access you don’t get from scrolling Instagram.
November 6–8. New York City. Open to non-members.

ShopMy just published a report on what drives creator sales. I read it so you don't have to.
The biggest takeaway: stick with the brands you already link to.
→ Creators drive 76% more orders per link by their 15th+ link to a brand than on their first
→ 83% of creator Black Friday/Cyber Monday sales in 2025 came from creators who had promoted the brand before November
Your audience has watched you link to these brands all year. Many of them are just waiting for a sale.
So don't spend November and December chasing new brands. Focus on the ones you already link to, and watch for their offers and opportunities.
I made 3 Claude prompts you can use with your ShopMy data. They find your best-performing brands and show when those brands have run sales in the past.
Comment HOLIDAY and I'll DM them to you.

New subscribers make the chart go up. Cancellations make it trickle back down.
Most paid Substacks only plan for the first part. On a monthly plan, every month is another chance for someone to cancel. Annual gives them one decision a year.
The full math is on Creator Math. Comment SUBSTACK and I'll send it.

Comment EPC and I’ll send you my free getting started guide.
Stop judging your affiliate links by conversion rate.
Here’s @juliaberolzheimer real ShopMy data:
Etsy converts at 3%.
Net-a-Porter converts at 0.5%.
Etsy converts 6x better. But Net-a-Porter makes us 4x more money from the same number of clicks.
It’s not commission rate either. J.Crew and Loeffler Randall both pay us 15%. J.Crew converts better. Loeffler Randall earns 2.5x more per click.
The number that matters is earnings per click (EPC). It combines conversion rate, commission rate, and order size into one number.
How to find it:
Take what each store earned you.
Divide by the clicks you sent it.
Rank your stores from highest to lowest.
Send more clicks to the top of that list.

@mommasociety is already posting her holiday gift guides and her audience is loving it. It seems like the holiday shopping season starts earlier and earlier each year. It makes sense to get a head start when the social and family calendar fills up. Lean into your shoppers mind set and help do the hard work for them. What's something you can post before the end of the month?

If your Substack posts aren't getting clicked, your title might be why.
We looked at 60,000+ clicks on Substack posts linked from Coreli pages. The posts people tapped told readers exactly what they'd get: a number, a price, a place, a clear story.
The 5 kinds of titles that get clicked:
Numbers + a price cap
"If I were…" + a limitation
A bold prediction
A real moment
A series that says what's inside
And the 4 that get skipped: too vague, too many topics, label only, too clever.
