I think we're in agreement. To be clear, there is no expectation that these items arrive in any particular order. What is important is that they all be present. Ordering is situation-dependent.

So to your point, yes, this is typically how I would write an email. In fact, the "I am" part of an email is often adequately covered by the 'From' address.

On the radio, in contrast, I would explicitly say something like "This is four-two, actual" before proceeding with the rest.
