Supernova Studio

Worked well for a while but then we started experiencing issues. Customers complained that they were receiving error messages when trying to register. The support team were not able to help with our issue so we uninstalled this app.

Thanks for taking the time to review the app and we're sorry you uninstalled it. The problem you describe was that the customer in question had unsubscribed previously. If this happens, they are unable to subscribe again - however our dev team can manually re-add the email address in this situation.

I Love Tunics

Great little app and very reasonably priced. I had issue with settings so emailed them and it was fixed within hours - so 5 stars from me

Hi - thanks so much for taking the time to review the app! We're glad it's working well for you and that our support team could help get it set up on your store.

Kind regards

Not working good and support takes too long. I have been using the app for days but its not 100%. Also e-mails notification delay to be delivery to costumers when I restock the item. I have been trying get it solved with support but they keep saying devs are working on my issue. It has been more than 20 days now, my free trial period its over and I am already being charged and the app it's not working good. Not a good experience.

Hi there

Thanks for your review and we're sorry you've been having issue with the app. We're in the process of migrating to a new server, which will improve the speed of the notification delivery but it will just take some time for testing etc.

Best wishes
