So far a good experience. Stu was a great help and support through the process. We already made some sales in the first week of use. Simple to use. Looking forward to the future use.

We've been using this app for over a year. It has been a simple and very relevant way to get users to come back. The support was super prompt whenever we've reached out to them. Easy to use app. Highly recommend!

Thanks for your super review Pragya, we really appreciate it. Great to hear how the app is helping your customers return via a Birthday campaign. It was a pleasure helping out.

The app is really good but the customer service is in a different league altogether! I don't use this app in the same way as most people might. My store is a Pet related business and I use this app to collect a dogs name and breed as well as the DOB. Over a few nights, Stu at customer support went above and beyond helping me to add additional features that I needed (metafields etc). Nothing was too much, even when I felt I might be becoming a pain with all my questions. Well done, I wouldn't hesitate to recommend this app to anyone.

We have been using the Happy Birthday App for a few years now and it's been a great addition to our store. The developers have consistently provided excellent support and have been really helpful with any queries and/or issues we encounter. Thank you so much!

The app is easy to set up, the documentation is detailed and thorough, but our experience with support completely blew us away.

Steve was extremely quick to respond to our emails and always had a detailed and relevant answer. He also anticipated our needs and proactively offered suggestions.

Thanks to his help, we were able to easily set up a two-way loop with Klaviyo so that:
1) birthdays collected in Happy Birthday are transferred to Klaviyo and seamlessly attach to our existing flow infrastructure for birthday offers
2) birthday we collected thru our existing channels are synced back to Happy Birthday, so we can make sure we are not asking our return customers for information they already provided.

Between the app's simple and lightweight design and unparalleled customer support experience, we are now reviewing other apps made by the same team and trying to find a use case for them.

You guys are amazing.

Thanks for taking the time to leave such a detailed and glowing review Aleksandar!!! It’s very much appreciated!

I’m really glad that you’ve been able to customise your Birthday Club to suit your needs by utilizing our Klaviyo webhooks feature.

It would be fantastic to have you on board with any of our other Shopify apps… I think you’ll love our Grapevine Surveys app ;)

Thanks again!

This app is perfect! Does exactly what we need it to do, and that's collect birthdays on the Order Status Page/Thank You Page. We integrate with KLAVIYO and everything works seamlessly. Support is always super helpful on the few occasions we've had to reach out with questions. All around a great app!

Thanks for the awesome review Clayton. It was a real pleasure working on a Birthday Club solution with you. Great to see it's working well and treating your customers on their big day.

These guys are awesome. Unbelievable support and guidance- AND FAST.

When we had challenges, they actually offered up a solution whereby we would no longer need to use their software.

These guys are really great. You're in good hands.

Our company has been using the app since 2023 and it's been great! The interface is extremely straight forward and easy to use. But Stu and the customer service team are what sets the app apart! Quick and helpful guidance!
