When a product sells out, the people clicking “Notify me” are telling you exactly what they want to buy. A back in stock email is one of the easiest sales you can make, as long as it’s set up right. 📩

Most of the problems happen quietly. If 500 people are waiting and only 40 units come back, sending the alert to everyone means at least 460 shoppers click through to a product that’s already sold out again. Sending in smaller batches, oldest signups first, gives more people a real chance to buy.

A few Shopify settings can also stop the alerts completely. If a product is set to keep selling when it’s out of stock, the “Notify me” button never shows up. And if the alert isn’t turned on before the product sells out, the people who already signed up won’t get it.

With Black Friday coming, this is a good time to check before your best sellers run out. 🛒 💻

Shopify Email has a new name. It’s now Shopify Messaging, and it sends texts as well as emails. The question for most stores is the same one it’s always been: is the free tool built into Shopify enough, or is it time to pay for Klaviyo?

For a lot of smaller stores, Shopify is enough. You get 10,000 free emails every month, and abandoned checkout emails don’t count against that at all. If you’re sending a few campaigns a month to a modest list, you may pay nothing.

Klaviyo starts paying for itself when your marketing needs to get smarter. That looks like sending a different message depending on what’s in someone’s cart, mixing texts and emails in the same automated sequence, or spotting customers who are about to stop buying before they do.

Most A/B tests don’t find a winner. One testing company looked at more than 127,000 of its customers’ experiments and found only about 12% beat the original.

That’s why picking what to test matters more than running lots of tests. If your store doesn’t have huge traffic, testing a new button color or a reworded headline will likely never give you a clear answer.

Bigger changes, like your offer, your pricing, or how a product page is laid out, are the ones your traffic can actually measure.

Shopify now has built-in A/B testing on the Grow plan and up. It’s a good place to start, with one catch: its storefront tests report conversion rate but not revenue. A change that gets more people to buy smaller orders can look like a win when it isn’t.

Two more things to watch. Some testing apps slow your site down for every visitor, not just the ones in the test. And calling a result early because the numbers look good after a few days is one of the easiest ways to make a bad decision. Decide when the test ends before it starts.

🚀 The new Hollis.com is live! 🎉

BLKDG partnered with Huish Outdoors to rebuild the Hollis homepage and launch a dedicated landing page for the Hollis Custom Rig Builder (CRIB), the only custom BCD builder of its kind.

Hollis has spent 40 years engineering technical diving equipment for cave explorers, research divers, and instructors in 70+ countries. Their new site now works the same way their gear does.

What launched:
→ A homepage built around the diver’s real problem: most gear is engineered for the average diver, and Hollis customers dive at the edge
→ A CRIB landing page that walks divers through three configurations (single tank, double tank, sidemount), every component of the rig, and a three-step process from build to in-person fitting
→ Clear paths to 600+ authorized dealers worldwide, so divers move from browsing to a fitted rig

The site now does what a good dealer does: names the problem, shows the system, and sends the diver to the right next step.

Congratulations to the Huish Outdoors and Hollis teams on the launch! It was a privilege to build this with a brand trusted on some of the most demanding dives in the world. 🤿 🌊

A Klaviyo segment doesn't send anything. It's a set of rules for who belongs in a group. Whether those people actually get an email depends on how the segment is connected to your campaigns and flows.

That's where a lot of accounts go wrong without anyone noticing. Segments don't check whether someone signed up for your emails unless you tell them to, so a segment can quietly include people who never opted in. A new automated flow built on a segment that already has people in it won't send to any of them. And a segment built on Shopify order tags that get added after checkout will stay empty, because those tags never make it into Klaviyo.

Sending to people who stopped opening your emails has a cost too. Inbox providers notice, and your emails start landing in spam for everyone.

Get the basics connected first: consent, who to leave out, and the flows your purchase data should be feeding. The advanced segments only pay off once those are in place.

A good ad account review should give you numbers you can check yourself, not opinions.

"Your account is set up wrong" is hard to act on. "You're missing 60% of the searches you could be showing up for because your budget runs out" is something you can fix.

We wrote a guide to reviewing a Google Ads account using Google's own rules. A few things stood out. Google's account scores are mostly a measure of how many of its suggestions you've accepted, not how well your ads are doing.

Some common setups count the same customer more than once, which makes your results look better than they are. And your daily budget isn't a hard cap. Google can spend up to twice that amount on a busy day.

If your numbers are off, every decision built on them is off too. Get the tracking right first, then cut wasted spend, then adjust the rest.

A PPC audit is a sequence of documented checks, not an opinion. Where to look in Google Ads, what a bad answer looks like, and what to ignore.

Your Shopify and Klaviyo retention numbers don't agree. Neither of them is wrong. They're just measuring different things.

We traced the retention stats everyone quotes ("5% retention lift = 25-95% profit," "acquiring a customer costs 5x more than keeping one") back to their sources. Three of the four have no source at all.

We also ran the real math on what a repeat rate lift is actually worth, and broke down exactly where Shopify and Klaviyo disagree on returning customers, cohort retention, CLV, and RFM.

If you've never stress-tested your retention reporting, start here.

AEO and GEO are not a new discipline. They never were. Google confirmed it in writing this July: this is SEO, running on the same ranking and quality systems as everything else. The industry keeps rebranding the same anxiety, and each rebrand is treated as a revolution that makes everything before it obsolete.

But four real controls now decide if your store shows up in AI search, and none of them are about content. A store can do everything right on the content side and still be invisible because of one setting nobody checked.

☑️ A new Search Console setting gates your store's AI visibility entirely, and it inherits from parent properties
☑️ Shopify's default robots.txt blocks the exact pages AI answers need to cite you
☑️ Cloudflare changes its AI crawler defaults on September 15
☑️ Three other switches get confused with each other constantly, and getting one wrong can make your store invisible with zero warning in your rankings report

We broke down all four, what Shopify already handles, and the exact order to check them in. Link below!

Most ecommerce loyalty programs get designed backwards. The app gets picked first, and the question of which customer behaviors you're actually willing to pay for gets answered later, if at all.

The default outcome of an unmanaged program is a subsidy. Your heaviest buyers redeem rewards for purchases they were already going to make, and the profit has to come from somewhere else in the customer base.

The peer-reviewed research on this is consistent: the actual return lives in your light and moderate buyers, not your top decile.

Our latest breakdown runs the effective discount math across seven DTC loyalty programs, traces four of the most-cited retention statistics back to their original sources (most don't hold up), and walks through what Shopify's platform gates actually decide for checkout redemption, tiering, and B2B programs.

If your program is running on vibes instead of margin math, this is worth the read: https://www.blkdg.com/blog/ecommerce-loyalty-program/
