Hello,
This is certainly a must in this kind of product.
In my project I need to send alerts to several mobiles, and I must know if it was received and when.
So the users does not say that they did not receive the alert. They should have the mobile ON all the time, I must have a proof that it has been delivered.
As you can see this is not a “one-user” request. I think we all need it.
Thanks,
JS
