The BIB Wine Company
The app works occasionally - but whenever we've had more than a handful of notifications it only sends a few before completely giving up. We've check our notifications settings and they should all have gone out. In the end we've had to send nearly 1000 emails ourselves, and weeks later have had nothing apart from 'all seems to be working at our end' from support. We do understand that we may have misunderstood the ramifications of the notification settings, however, we have asked about this and have also had no response and there is next to know documentation to go with the app.
When it works its great, but there is also very little flexibility in the system. For example, having emailed people manually when the app failed, we can now see no way to cancel or disable old notifications in waiting, which basically renders the whole app useless as we've had to set the inventory parameters unrealistically high in order to prevent the emails from being arbitrarily triggered and our customers receiving extra emails.
We're going to stick with it for a little while longer to see if we can battle through, but with no change will have to move to something coded better, with more flexibility and better support.
