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.

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 am very new to Shopify and starting my on line boutique from scratch everything is a learning experience, trying to bring more customers to the store is challenging to say the least! This app is a very easy and useful tool to help bring customers to your site. Its defiantly worth at least trying out first, but i am sure anyone that uses it see how easy it is to set up and will continue to use it after the free trial.

it would be better if it integrated better with Shopify admin and added other apps
