15 Back-in-Stock Email Examples That Actually Convert and Drive More Sales

What are back-in-stock emails?

Here’s a back-in-stock email from my own inbox, from British brand Damson Madder. Please don’t judge me for having almost 10,000 unread emails.

The main purpose of a back-in-stock email is simple: to inform customers that a product is available again and give them a chance to complete a purchase.

In general, emails like this are sent to customers who’ve shown interest in the product. This includes people who signed up for restock notifications, joined a waitlist, or viewed this product.

In practice, however, many brands don’t treat back-in-stock emails strictly as one-to-one alerts, but rather as broader restock announcements. In cases like that, emails can also be sent out to interest-based segments, such as customers who browsed similar products, purchased from the same brand, or engaged with related categories. 

This is what happened with the email from Damson Madder above: I never asked to be notified about this particular skirt, but I have bought a skirt from this brand before. So, in this case, the email is based on my previous engagement with the brand.

Why back-in-stock emails matter: Key benefits

There’s a reason these emails are such a big deal: they work, and they work really well. According to 2025 research by Omnisend, automated emails in general perform much better than regular campaign messages. 

For back-in-stock messages in particular, open rates reached 59.19% and conversion rates around 5.34%. And brands know about this: back-in-stock emails were one of the fastest-growing automation types year-over-year, with send volumes increasing fourfold.

Let’s have a look at some of the advantages back-in-stock emails offer.

Increase conversions with high-intent shoppers

We already know these emails convert well. Here’s why. 

Back-in-stock emails are sent to people who have already shown interest in a product. In other cases, brands send restock emails to broader (but still relevant) audiences. Either way, these emails reach people who are more likely to make a purchase, as opposed to a general promo audience.

They also tend to include urgency signals, an important part of FOMO marketing. This can be a note about limited quantities, high demand, or the risk of selling out again. 

Together, all of these factors mean that these emails often convert better than standard promotions.

Recover lost revenue from out-of-stock products

Beyond increasing conversions, back-in-stock emails can also help brands recover revenue they lost due to temporary stockouts. When a product is out of stock, it means that a purchase was interrupted, rather than that people stopped wanting it. 

Back-in-stock emails help reconnect that sale once the supply issue is resolved. Instead of focusing on attracting new users, brands can turn existing interest into sales by bringing shoppers back when the product is available again.

Build customer loyalty through transparency and trust

Even though back-in-stock emails are automated, they still count as proactive communication. Instead of the brand just silently updating its inventory, it lets customers know that the product is available again. 

This shows that the brand remembered the shoppers’ interest and followed up. It also sets clear expectations around availability and saves customers from repeatedly checking product pages. For the recipient, this makes the brand feel reliable, responsive, and customer-aware.

How to write effective back-in-stock emails

Even though the emails above come from different e-commerce sectors, they have a lot in common. In this section, we’ll have a look at what makes a back-in-stock email effective and how you could get started with restock emails of your own.

Highlight urgency and scarcity

Back-in-stock emails work best when they remind customers that availability may be limited. 

After a restock, quantities are often small, and popular items can sell out again quickly. Simple time-based cues like “back for a short time”, “limited quantities”, or “while stock lasts” can help encourage action. However, this approach requires moderation — you don’t want to come across as spammy. 

Personalize your messaging

Personalization is so, so important for email marketing. And these days, it goes beyond addressing the customer by name (but it’s good practice to do so anyway!). 

So, use all the customer data that you have. Mention the exact product the customer showed interest in and match the message to their past behavior — whether they viewed the item, joined a waitlist, or abandoned a purchase. This makes the email feel relevant.

Show what makes the product special

Back-in-stock emails aren’t a good place for a full product description or any unnecessary tech jargon, but it’s a good idea to quickly remind the customer of the product’s key features. Highlight one or two key features or qualities, such as the design, functionality, or popularity of the item to jog the recipient’s memory. And don’t forget to add strong images to reinforce everything.

Add social proof or reviews

In emails, social proof usually appears as customer reviews, ratings, testimonials, or labels like “bestseller” or “customer favorite.” It helps confirm that the product is worth buying, as well as reinforcing demand and reassuring shoppers.

Keep the CTA clear and direct

A CTA, which stands for “call to action”, is the button or link that tells customers what to do next. For example, common CTAs for back-in-stock emails include phrases like “Shop now” or “View item”. Use simple, action-oriented language and avoid adding multiple competing CTAs.

Subject line ideas to boost open rates

There’s one thing all marketing emails have in common: the subject line you choose can either make or break your campaign. That’s because the subject line, together with the preview text, is often the first thing your subscriber sees. We’ve collected some of the best back-in-stock subject lines you can totally steal for your next campaign.

• It’s official: [product name] is BACK
• Guess who’s back in the house
• Back in stock on all your favorites
• (finally) back in stock 🦋
• We brought something back for you
• Missed out last time? These sold-out pieces are back in stock
• [Product name] has returned ✨

• Hurry! [Product name] is back in stock
• BACK IN STOCK: [product name]
• Our BIGGEST back-in-stock delivery… maybe ever?

How to set up a back-in-stock email campaign (step-by-step)

Let’s put all this theoretical knowledge into practice. Here are a few simple steps you can take to set up your own back-in-stock email campaign. 

Enable back-in-stock notifications on your website

To set up a back-in-stock campaign, you first need a way for shoppers to ask to be notified. 

This usually starts on the product page when an item is out of stock. Instead of an “Add to cart” button, show a clear CTA like “Notify me when available”. These notifications perform best on individual product pages, rather than on category pages. Try to keep the signup process simple, and in most cases, just asking for the customer’s email address is sufficient.

Once a customer signs up, it’s also a good idea to confirm that their request was received. Here’s an example of an email like this:

Segment customers who requested updates

Segmentation means splitting your email list into smaller groups based on customer behavior, traits, or interests, so you can send more relevant messages to each group. 

If we’re talking about the simplest setup for back-in-stock emails, you don’t need to segment your audience at all. When a customer signs up for a restock alert, the email is sent automatically as soon as the product becomes available again. 

However, as we’ve seen above, many brands send out broader restock announcements, cover multiple products at once, or target customers based on past behavior rather than a single request. Here, segmentation makes sense. 

For example, you could create a segment of customers who previously purchased from the same collection or product line, who engage with products of the same category, or browse related items.

Prioritize high-value or VIP customers

Not every customer is the same. Some of them buy more from your brand, engage with your content more, or regularly engage with promotions. These are your VIPs, and you should prioritize them for your back-in-stock emails. 

For example, you can send restock emails to this group first or give them early access before opening availability to a wider audience. This makes loyal customers feel like they’re appreciated.

Automate your workflow in the email platform

We’ve already mentioned several times that back-to-stock emails are automated. But what does this mean, exactly? 

If you’re using an email service provider like Selzy (and you’re running email campaigns, you really should), you’ll be pleased to learn that they often support trigger-based automation. This means an email can be sent automatically when something happens on your website or in your store. For back-in-stock emails, this is when a product’s stock status changes from “out of stock” to available. Another relevant example of trigger-based automation is when a customer signs up for product notifications, they receive a confirmation email that was triggered by this action.

Once the trigger fires, your ESP can do the following:

• Send the email instantly, without you needing to do anything.
• Pull dynamic content like product names, images, or links.
• Repeat this process many times across many products.

Here’s how you can set this process up in Selzy. The image below shows a scenario for a welcome email, but the general idea is the same.

In most cases, your back-in-stock email should be triggered the moment a product’s status changes from out of stock to available.

Track performance metrics (CTR, conversions, unsubscribes)

Once your campaign is live, the work doesn’t end there. It’s always important to check how your emails are performing, so don’t just forget about them as soon as you’ve released them into the wild. 

There are several metrics to help you gauge how well your emails are doing. The good news is that your ESP can also do all of that work for you, so you don’t need to calculate anything. This is Selzy’s dashboard, where you can see all the metrics and stats. 

Now, let’s get specific. For back-in-stock emails, some metrics are more important than others.

• Click-through rate (CTR) shows whether people are interested enough to click through from the email to the product page. A strong CTR usually means the message feels relevant and timely.
• Conversions show you how many customers actually bought after clicking. So, for back-in-stock emails, it’s completing a purchase after receiving the email. This is the clearest signal that your back-in-stock emails are doing their job.
• Unsubscribes are somewhat of a warning sign. If people unsubscribe after receiving restock emails, it may mean you’re sending too often, targeting the wrong audience, or promoting items they don’t really care about.

FAQ

What’s a back-in-stock email?

It’s an automated message that lets your customers know when a product has become available again. These emails are usually sent shortly after the item has been restocked.

Who gets back-in-stock emails?

These emails are primarily sent to people who expressed interest in the product in the past. This can include customers who signed up for alerts, joined a waitlist, or viewed the product earlier. Many brands also send back-in-stock emails to people interested in similar products.

Are back-in-stock emails promotional?

Not exactly. Back-in-stock emails are sent to share information about an update rather than to promote something. That said, many of them do include product details, reviews, or special offers to help customers decide.

How quickly should you send a back-in-stock email?

Back-in-stock emails work best when they’re sent as soon as the product becomes available again. At that point, customer intent is still high, and the product is top of mind. Delaying the email for too long increases the chance that shoppers lose interest or buy from another brand. 

Do back-in-stock emails need a discount to work?

No, discounts aren’t required for back-in-stock emails to be effective. Since these messages are sent to customers who already showed interest in the product, the restock itself is often enough to drive action. Many brands rely on urgency, limited availability, or social proof instead.
