If your abandoned cart emails have stopped converting, one of the most causes we’re seeing at the moment is stock holdings, not copy. When a top-selling product is out of stock, or a cart sits just under your free shipping threshold, the customer is waiting on availability rather than a nudge. Check your sell-through rate, your reorder lead times, and your product views against add-to-carts.
Now, some questions I always ask first. These are your must asks. Have I got an automated abandoned cart email flow set up? Do I know how well it’s converting?
If you’re finding a dip in your cart abandonment email performance it might not be because of your abandoned cart offer, or the content itself. It might be simpler than that, it might be related to what you have in stock right now.
As biz owners we’re so accustomed to first look at content performance, however when a top-selling item goes out of stock or customers can’t reach the free shipping dollar value the cart gets abandoned. Cart Abandonment flows won’t convert those people no matter how well written, or how enticing the offer, because in these instances the customer is waiting on the stock item they want, not a nudge.
Two things often stop a cart in its tracks.
The first is an A-grade product going out of stock. Your customer has come in for that item specifically. They can see it, she can’t add it, and the rest of your range doesn’t replace it. Research shows 69% of shoppers will immediately leave and buy from a competitor when they hit an out-of-stock item, no abandoned cart email recovers that (Open/send).
The second is your free shipping threshold. Imagine your cart sits at $90 against a $150 threshold, and the one product that would have closed that gap is the one that’s unavailable. So they leave their cart open and wait. This matters more than it might seem, 58% of shoppers actively add items to reach a free shipping threshold (ClickPost/Spotify), and 47% abandon their cart entirely when they can’t qualify (NRF). Your prospective customer isn’t being difficult. They’re doing exactly what most shoppers do. And no abandoned cart email fixes a gap that stock was supposed to close.
In both cases, they didn’t leave because your offer wasn’t good enough. They left because there was nothing else for them to do. No abandonment flow converts that person. It doesn’t matter how well it’s written or how enticing the discount. She’s waiting on stock, not a nudge.
What this looked like for one client
A client of mine had their top-performing women’s shirt go out of stock.
The pattern was visible in the data. Cart values were sitting under $150. Customers were viewing that specific product page and not adding to cart. They dropped off right at that point. The scenario below is based on a real client scenario, figures have been adjusted to protect privacy, but the pattern is one I see consistently across ecommerce clients.
Over a six-week period, the product page received 2,140 views. Of those, only 96 converted to an add to cart, a rate of around 4.5%, against this product’s usual 19–22%. The traffic hadn’t dropped. The audience was still arriving with intent. There was just nothing to add to cart.
So instead of relying on the abandonment sequence to do a job it couldn’t do, they signalled “notify me when back in stock.” Purchases resumed once stock returned.
Within a three week period, 52 customers had signed up to the existing “notify me when back in stock” prompt. In the first week the product returned to stock, 38 of those converted to a purchase.
That solved the immediate problem. But the real find was that their reorder lead time was too long. Historically, this client waited until a product was fully out of stock before reordering. Which meant every customer with genuine intent to buy waited out that entire lead time alongside them.
We moved the reorder trigger from zero stock remaining to eight weeks of cover. Stock now lands before it runs out rather than after. In the following quarter, that product line recorded zero stockout days. Abandoned cart conversion returned to its previous baseline within six weeks, and stayed there.
The email flow hadn’t been the problem. The stockholdings had. Because when A grade stock is out, cash flow halts. Replenishment rates slow. And the email flow takes the blame for something that happened in the warehouse.
I’ve seen this same challenge across a lot of my ecommerce clients. Particularly over the last 12 months. Which is why I wanted to share, in case it’s something you haven’t looked at yet.
Two approaches to consider
1. Raise minimum stock holdings on your A-grade products.
These products drive purchasing behaviour well beyond their own line item. They’re often the reason a cart gets started, and the reason it clears your free shipping threshold. When they’re gone, the rest of the cart tends to go with them.
Your A-grade products don’t need the same buffer as everything else. They need more.
2. Reorder earlier, rather than at zero.
Zero is too late. By the time you’re at zero, your customers are in the queue with you, and you’re paying to acquire traffic for a product they can’t buy. Set the trigger on weeks of cover, not on an empty shelf.
Where to look for this
You know what I’m going to say. You’re going to have to look at your historical data. Here’s what that means in practice. This is a 30-minute job, not an afternoon.
- Find out which products are A-grade. In Shopify, the ABC analysis by product report grades your range by the revenue it contributes. Anything sitting in A is what we’re talking about here. If you’re not on Shopify, sort last 12 months of sales by revenue per product and take the top 20%.
- Look at your sell-through rate on those products. How fast do they move, and how does that change across the year? That run rate is what tells you how much cover you actually need.
- Check your product page views against add to carts. In GA4, the ecommerce purchases report shows items viewed, items added to cart and items purchased side by side. When a product is taking views but almost no add to carts, that’s your stockout showing up in the data. You’ll see the exact weeks it happened.
- Compare your average cart value to your free shipping threshold. If carts are consistently landing just underneath it, the threshold is doing something to behaviour and it’s worth knowing what.
- Then look across 24 months, not 12. One year shows you the trend. Two shows you the sales periods, and which spikes repeat.
That’s what turns a reorder point from a guess into a forecast you can hold up.
This is reviewing the tapes. The answer was already in the footage. Nobody had gone back to watch it.
A short checklist
- Pull your top five products by revenue over the last 12 months
- Work out the weekly run rate for each one
- Check your supplier lead time in weeks, honestly
- Set your reorder trigger at lead time plus a buffer, and hold to it
- Look at the weeks your product views spiked but add to carts didn’t
- Where to start
