Scored on 26 merchant reviews we hold for Happy Birthday Marketing, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 26 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 26. Open one to read it in full, with the developer's reply where there is one.

I really like this module; it looks very promising. Everything is simple and ingenious, with nothing superfluous. Unfortunately, however, I have to uninstall it after setting it up because it’s missing one crucial and essential configuration option: how many days before the birthday to send the email with the promo code. In this module, that setting is fixed and cannot be customized. The instructions state that the email is sent at 10 a.m. on the birthday itself. For industrial goods, that’s +/- OK. But we sell food—and in Germany, no less. People here plan everything six months in advance. Plus, it’s impossible for us to take same-day orders; the minimum production time is two days. I’m writing this review to bring this shortcoming to the developers’ attention. I think there are thousands of sellers like me who need this feature as a customizable option. If possible, please let me know as soon as you implement this in the new version—we’d be happy to use it.

Developer repliedThanks for the feedback. You're absolutely right, a fixed send date doesn't really work for businesses like yours. That's a great suggestion and I've added it to our feature roadmap. I can't commit to an exact timeline right now, but if you drop me an email at chris@northern-apps.com I'll make sure you're the first to know when it ships 👍 Chris Show more

App is very easy to use and Chris was great when I had some questions on setup. We've had 1 successful code use so far and hope to have more in the future as we grow our site following.

Fantastic app! It’s brought in a surprising number of sales, and setup was quick and easy. A smart way to build customer loyalty.

Our clients love that we have used this app, it made a birthday sign up super simple for them. We can give them a bit of appreciation without difficulty. We have an older client here in Florida, and this app is easy to use for them too!! Thanks for such a great, user friendly app!!

This app was exactly what I was looking for to add to my shop :) It was very easy to install, and Chris was incredibly helpful if I had any questions ! I’ve received lots of positive feedback from customers who appreciate the special incentive sent to their inbox on their birthday :) I highly highly recommend this app !! Customer service was top notch as well :)

Well rounded app to capture customer birthdays at different touch points (landing page, thank you page, etc) Very easy to set up, includes email marketing features and allows to track birthday discounts. The customer support is superb! Thank you Chris.

I would like the coupon set-up to have more options. I want the discount to be for one specific product or collection, and the app sets it up for every products/collection. So even special releases will get the discount.

This app is easy to set up and does exactly what we need it to do. Customer service is quick to respond and very helpful as well. Great app!
