Scored on 118 merchant reviews we hold for Happy Birthday Email by UW, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 118 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 118. Open one to read it in full, with the developer's reply where there is one.

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.

Developer repliedMany thanks for your kind review. It was a pleasure helping to customise your Birthday campaign and it's great to hear that you're already seeing results. We're always happy to help further if needed. Show more

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!

Developer repliedThanks 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. Show more

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.

Developer repliedThanks for this super review Mike. It was a pleasure to help put those customisations in place for you and great to see them being used in such a creative way. We're always keen to help where possible. Thanks again. Show more

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!

Developer repliedThank you for your kind review Nabilah. It was a pleasure working with you and helping set up your integration. Great to hear that all is working well. We'll be here if you need us again. Show more

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.

Developer repliedThanks 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! Show more

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!

Developer repliedThanks for the great review Deagan, we're really pleased that you like the app. Keep up the good work on your Birthday Club! Show more

I really do support this app. It's fairly easy to set up. Stu is fantastic to work with! This functions just like you want it to.

Developer repliedThanks 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. Show more

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.

Developer repliedThanks for the super review Eric. It was a pleasure helping integrate our Happy Birthday app into your customised Birthday campaign. It's all working nicely! Show more
