Include subscription activation in the lead generation notifications
Marketplace implements a lead notification mechanism that works well when someone get interested in your offering through Marketplace. We can configure several ways to get alerted on that, receiving information about the lead.
Surprisingly enough for me, if the customer directly goes to Azure portal an subscribe to our offering we don't receive anything and there is no way to define an alert for such circumstance, so we cannot proactively contact the customer to provide support.
Please, set that pretty simple functionality (probably the simpler way would be to integrate it with the existing lead generation alerts).
