Initially I had issues with the integration between Shopify, HBD, and SMSBump. However, both SMSBump and HBD worked to get it squared away. It appears to be working now. I still have a few more questions that need to be answered and I will update the review if all is well.

Very easy to setup and quite a powerful tool. We had an issue and customer service helped us to solve immediately.

I simply love it.
Simple to use, and generates sales.
It can be integrated in a lot of places and I love the fact that adds a tag on customer with the birthday date so if you have the customer in store you can see it's his birthday.
Support is excellent too.

Great app, well designed and works well. We have it installed on 3 stores and see good conversions from the Birthday email send outs. Support is very proactive and responds quickly. Highly recommended.

Added this application to see if we can increase our turnover by offering a nice discount code on our customers birthday, and yes, it does work! People like to treat themselves on their big day., Customer service is also on point.

I find it very convenient although I would have preferred to be able to set the language directly in the settings et to manage the appearance of the sign-up page so that it would match with my theme.

I absolutely love the app and their customer service is great ! Thank you so much for your help and great work.

Great app, the team were extremely helpful in getting this set up for me. They were extremely responsive and helpful with getting our landing page to look how we wanted it to. Massive thanks

Can't limit what they purchase, how many they put in their cart. We sell high end items and want to limit it to one per person. No way to verify what their birthday is with this program. Not customizable enough

The support team was super helpful with the entire set-up process and assisting me with our brands specific needs. We've already been able to capture a ton of client birthdays with target specific promotions! I highly recommend this app!
