Nothing is more annoying to an online shopper than finding out their coveted item is out of stock. The silver-lining, however, is in the detail – it shows that product demand is high. For e-commerce businesses, keeping customers informed about product restocks can turn potential missed opportunities into sales. It's here that back-in-stock alert apps come into play, enhancing customer engagement and creating a seamless shopping experience. Today, we delve into the features, costs, and efficiency of two such apps: Wishlist Engine and Back In Stock via Messenger.

How Does Wishlist Engine Work?

The Wishlist Engine, developed by Script Engine, offers amicable solutions to e-commerce businesses by quietly monitoring and tracking product restocking. With features like auto emails, price drop and restock alerts, and guest wishlists, this app is strategically designed to generate sales by transforming customer's wishlisted products into a sale. The Wishlist Engine seeks to assist both customers and merchants. From a user point of view, they have at disposal a tool to bookmark their favourites and save the trouble of searching for the same product later. In contrast, from a merchant's perspective, they gain insight into products most saved on the wishlist and have a chance to follow up with customers and turn potential sales into confirmed ones – a formidable way to boost revenue. An example of the practical application of this app could be a small clothing store where customers save several items to their wishlist prior to a major sale event. Using the insights and email marketing features of Wishlist Engine, the merchant can successfully convert those wishlists into sales when the products are back in stock, thus increasing the revenue and customer satisfaction.

How Does Back In Stock via Messenger Work?

The Back In Stock via Messenger app, developed by ASoft, is a versatile alert tool that capitalizes on the popularity of Facebook and Messenger. The app notifies customers about product restocks directly through Messenger, offering a surprisingly direct line to potential buyers. A major highlight of this app is its "Most Wanted Section," making it simpler for merchants to track product demand. The ability to customize the "Send to Messenger" button size, view comprehensive customer activity details, and receive email updates add icing to the cake. With capabilities similar to the Wishlist Engine, like product restocking notifications and detailed product request analytics, this app poses stiff competition to its competitor. Imagine an online electronics store launching a new product, which gets out of stock within a day. Using the Back In Stock via Messenger app, the store can alert customers directly when the product restocks, and quick customer actions might result in instant sales.

How Much Does Wishlist Engine Cost?

The pricing of an alert management tool like the Wishlist Engine plays a crucial role in decision-making for many online retailers. The Wishlist Engine offers three tiers of pricing – a Free Plan, a Basic Plan at $4.49/month, and an Advanced Plan at $9.49/month. The Free Plan covers basic wishlist functions, the Basic Plan offers an unlimited Wishlist and branding options, while the Advanced Plan adds powerful features like Auto Reminder Alerts and Price drop/Restock Alerts.

Their Startup plan begins at $4.99/month, followed by the Professional plan at $14.99/month and the Enterprise plan at $49.99/month.

Cost Analysis: Wishlist Engine vs. Back In Stock via Messenger

Comparative pricing analysis reveals that the main differentiator lies in their top-tier offerings. While Wishlist Engine's highest-priced plan is available at $9.49/month providing features like the Auto Reminder Alert and Price drop - Restock Alert, Back In Stock via Messenger, at its premium Enterprise plan of $49.99/month, offers unlimited notifications.

User Reviews & Customer Support Insights

Is Wishlist Engine good?

With a whopping average rating of 4.9 stars from 189 reviews, there's strong evidence to suggest Wishlist Engine is a hit among users. However, it's always wise to look beyond star ratings, and there's plenty to consider with this app.

Is Back In Stock via Messenger good?

The Back In Stock via Messenger app sports an average rating of 2.3 stars, from only six reviews. From a first look, consumers might perceive the app to be less popular or appreciated. However, with a smaller user base, each review carries more weight, so the lower score could have more to do with a few isolated user experiences than an overall measure of the app.

User Preference: Wishlist Engine or Back In Stock via Messenger?

Based on the review count and average ratings, Wishlist Engine seems to edge ahead as the preferred choice for users. It's important to note that the features and functionality of these apps may better suit different users or business contexts.
