About RN: PreOrder & Back in Stock

Add Preorders and Notify Me When Available buttons and send back in stock alert so shoppers get notified when you restock. Send SMS, email, and WhatsApp Back in Stock alert automatically. With the Preorder now button, sell out-of-stock products by taking prepaid deposits. You can also show a low stock "Only X left" widget and real-time stock level display on the product page. The Back in Stock Alert works at variant level and syncs variant stock and inventory across locations.

I was looking for a back-in-stock app that sends alerts via WHATSAPP. I found this. The pricing is fair, and everything seems so easy, I really don't even know how to explain it. I'm a happy user here! You guys are wonderful.

I can't help recommending this app enough! If you're looking for a back in stock alerts app that is fully customizable, this is the one. Know that you'll always have live chat support which is also super quick. It seems they never sleep and always there for your concerns.
— Shopperium Global
A big thank you to the app builders and support team. I had a question about preorders and it happened I was chatting with both of them in the same chat lol, they are eager to help and support not only with the app but also anything they could.

Simple app, does what a shopify store needs. Everything is well so far. I send automatic back in stock alerts when I bring more products in. and the support team - they are amazing and fast. What to expect more?

Remind Stock Notification has made managing low inventory much easier for my store. The alerts help me restock before products run out, and customers stay informed without confusion. It’s simple to use and has brought real value to my daily operations.
— Luxovelle
We restocked a sold-out products after big promos but with this app I dont need to turn off the ads, and within 3 hours we had 7 orders from shoppers who signed up through RN app. That alone paid for the app. Support from Ardis was personal and helpful. Thank you.
— Luxe Dubai
We tried two other notify-me apps before RN and this one feels more solid. We're still setting up our store but I'm already confident with this guys. their app is new but looks like they did great their job. it matched style to our brand colors without touching anything. what I love is it shows clearly which variants customers subscribed to, and you can see events too. Very happy so far.
— Little Joys
I loved this simplicity and speed: first - integration of this app with Shopify inventory is solid. emails trigger correctly when stock updates and no delays so far. I've checked it on a few apps, and this one was working really fast that other ones. finnaly; app widgets doesn’t slow down our site, which was important for us. Had one minor customisation request and Narmina resolved it the same day...
— Limit Maker
After trying a few notify apps, this one was the simplest to set up and actually worked the way we wanted. The support is great and fast for resolutions.
— Pawzato
We’re a small cosmetic store and needed something affordable but powerful. The app works smoothly and the “Notify Me” button looks professional. When we activated, Ardis made the setup seamless. it's a must app!
— Lushè
We installed RN mainly for back-in-stock alerts. The button looks clean and reflects perfectly with our theme. the team actually cares, Nurlan personally helped us, super responsive.
— Xclusive Mart
Notify Me buttons are an absolute game-changer! Restock alerts not only recover lost sales but also keep customers engaged and excited. Super simple to set up, and they work flawlessly. Highly recommended for boosting conversions and customer satisfaction!
