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!

This app is fantastic! I love that I had the opportunity to customize a lot of the elements for how this app is implemented. After a few weeks I had a small hiccup with how my birthday members were subscribed so I reached out to the Happy Birthday team. A member on their team, Stu Jones, worked tirelessly to make sure that our app was functioning perfectly. I cannot speak highly enough about how Stu helped our company. I HIGHLY recommend this for any business!

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!

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.

Stu and the team have been great! We needed some assistance due to an issue on our end with historic set ups, and they worked tirelessly to get us up and running.

Our conversation rate is fab!

Thanks to Stu and the team - great app!

Fantastic app and support team! The app does what it says it'll do, and it's very easy and straightforward to set up and use. Pricing is very reasonable.
