You are the administrator of the ACME banking group. You are responsible for designing a notification system that will send a confirmation email to users when they purchased a new service. The solution also requires to make use of distribution lists as well as collecting real-time metrics of who blocked email engagement. Which of the following technologies would best fit the design?
SendGrid is correct, as this is an email solution that provides email functionality via distribution groups as well as metric gathering. Notification Hub will not suffice as this is used to send PUSH notifications on a large scale. Event Grid would not suffice as this is used to provide developers access to the events generated by cloud infrastructure. Service bus will not suffice, as this is a messaging service and not a notification service.
