Given a sentence containing a direct object like:
Le enviaré las fotografías
if I want to clarify the pronoun as "usted", where do I put the explicit pronoun? Does it go before or after the direct object? Or can it go in either place?
In other words, which would I write?
Le enviaré a usted las fotografías.
Le enviaré las fotografías a usted.
Or are both of those sentences grammatically correct?
