This app falls short and has bugs. The support team have been useless (two weeks with no solutions).
First bug, the EMAIL WHEN AVAILABLE button will show on variants that are in stock (which is confusing).
Second bug, logo image keeps dropping from the email template.

Easy to use and install. Integrates to match store's theme. Developer was responsive and very helpful with an advanced customization request and an inventory error. Recommended!


Incredibly unintuitive app, difficult to navigate and impossible to get any kind of support. I downloaded this app for one purpose; to notify my customers when the size they require for a certain product is back in stock. I have had the app for 2 weeks now and still have not had success. The company are extremely unhelpful and it is almost impossible to speak with a human being! Awful experience.
