This is where back-in-stock alerts become important! 

As an increasing number of businesses worldwide are using WhatsApp, this blog explains why you should use it to send back-in-stock notifications on WhatsApp and provides tips on how to do so effectively. 

Learn how to leverage the number one instant messaging app for sending back-in-stock alerts on WhatsApp and keep your customers informed about your product availability. 

What is a back-in-stock alert?

A back-in-stock alert is a notification that a retailer sends to customers who have previously expressed interest in an out-of-stock item. It alerts them when the item becomes available for purchase.

A back-in-stock alert sends notifications for:

  • Products that were out of stock but are now available for purchase again
  • Sizes or colors that were previously unavailable but are now restocked
  • Items that were on pre-order or backorder and are now ready for shipment
  • Limited edition or exclusive items that have been restocked
  • Products that were in high demand and sold out quickly but are now back in stock.

Many well-known e-commerce retailers, including Amazon, Walmart, Tesla, and Fashion Nova, offer the option for customers to subscribe to back-in-stock alerts helping to draw interested shoppers back to make a purchase.

However, many businesses still rely on email to send back-in-stock alerts, despite the fact that the overall average open rate for emails is around 17%. By contrast, messaging through the WhatsApp API has an incredibly high open rate of 99%, making it a more effective and efficient method for sending these alerts.

In today's fast-paced digital world, businesses need to find new and innovative ways to reach out to their customers. 

With WhatsApp's open rate, WhatsApp messaging allows for a higher chance of customers seeing and engaging with back-in-stock alerts, ultimately boosting customer revenue.

Here are some other reasons why sending back-in-stock notifications on WhatsApp can be an effective strategy for notifying customers about restocked items.

Customers can not only receive back-in-stock notifications on WhatsApp from businesses but also initiate a conversation to know more about the products.
