Best Practices for Back-In-Stock Alert Emails

Best Practices for Back-in-stock Alert Emails

Online shoppers get disappointed when the product they are looking to purchase is out-of-stock. This is majorly seen during the launch of a smartphone when it gets out of stock even before the user has added it to his cart.

Then they just wait, wait, and wait unless there is another option. And there is a sense of excitement when that product is back in stock.

I can relate to this very well. I wanted to purchase a smartphone. When I looked for my desired smartphone on Amazon, it was unavailable, went out of stock from the smartphone brand’s website as well and wasn’t available anywhere else. So, I subscribed to get notified about it as soon as it returns to the store.

A few days later, I got the notification that the product is available to buy. Without wasting any further time, I quickly opened the email, clicked on the buy now option and purchased the phone.

This is where the role of back-in-stock alert emails becomes crucial. A single back in stock email can bring you huge revenue. A case study done by Marketing Sherpa revealed that back-in-stock alert emails have around a 22.45% conversion rate.

If you do not take the onus of informing your visitors when the product becomes available again, they will likely search a competitive product on other online shopping websites.

What is Back-in-stock Email?


A back-in-stock email is an email that is sent to those users who have subscribed to receive updates regarding an out-of-stock product. When the product is back-in-stock, the shoppers are informed via email about its availability so that they can purchase it as soon as possible or before it goes out of stock again.

Many of the users can miss out on the purchase if they aren’t notified and this eventually leads to some lost revenue.

The sole purpose of the back-in-stock email is to boost your sales. Besides, it helps you drive huge traffic to your website, encourages customer retention, helps you understand the touchpoint of your customers, and builds a strong connection between the brand and the consumers.

Back-In-Stock Email Best Practices

We will start from scratch. For a back-in-stock alert email, keep the following points in mind.


1. Do Not Remove Out-Of-Stock Pages

It is never a wise idea to hide the out-of-stock product pages from your website. How will consumers even know that the product is just out-of-stock? If they browse your website, search for and product, and find a 404 page, they will simply think that the product was never available in your store. Moreover, it will leave a negative user experience.

The concept of back-in-stock email would not even work if out-of-stock product pages are not visible.

So, simply include an out-of-stock tag on the product and place a “notify me” call to action, clicking on which users will be asked to specify the email address on which they want to get notified about the product availability once it is back in stock.

You can also take the help of Exit Popup, so when a user tries to exit your website after seeing that the product is out of stock, the popup appears asking them to get an alert over their email address once the product is back in stock.

2. Grow Your Email List

Many of your users might not have subscribed to your newsletters or promotional emails. So when someone clicks on the “notify me” option, having a newsletter checkbox along with the email address field can help you grow your email list further.

This will not only be beneficial to sending back-in-stock alerts but you can target those users in other email campaigns as well.

3. Write a Persuasive Subject Line

Users will be excited to know that the product they desired to purchase is back in stock. Increase the excitement by writing a compelling subject line.

Since the subject line has to be in limited words to make it visible, it must start with “Back in Stock,” followed by the product name. This will immediately make it clear to the visitor what the email is about.

After that, you can use the call to action like “Grab it ASAP”, “Limited Stock Available”, and “Hurry, selling fast”. These sorts of tags are highly effective in creating urgency.

4. Short and Crisp Email Content

Shoppers would want to grab the product as soon as it is available. Do not let them waste their time in reading the email content. Keep only the necessary information in the body.

What should you include in the email content?

Use the product image for sure. Visuals tend to make the purchase decision even stronger. Apart from this, write a short and persuasive text. Use large and bold font to highlight the main point. Use an alluring CTA like “Shop Now” or “Buy Now”. Also, it should be clearly visible.

5. Email Follow-Up

It is likely to happen that your subscribers miss out on your back-in-stock email due to some reason. Therefore, it is recommended to take a follow-up after a while if the product hasn’t gone out of stock.

This will push customers to purchase the product once they realize that they missed the opportunity to get the product in the previous email.

You can also inform the back-in-stock alert subscribers even when the product quantity is low or when the consumers have added the product to the cart but forgot to purchase, just to make them purchase the product before it goes out of stock again. This helps to reduce cart abandonment as well.

6. Back-In-Stock Alerts on Wishlist Items

Many online shoppers add the product to their Wishlist so that they do not have to search again for that product when they return to the store next time. Wishlist items also indicate that customers have the intent to purchase it.

So, if a Wishlist item goes out of stock, make sure to remind customers when it is back in stock. Tell them that the product they wished to buy is now available for purchase.
