Both indirect and direct object pronouns and nouns in one sentence? Por que?

Question

Hola!

I'm having a hard time wrapping my mind around the purpose of doubling down on the indirect object usage in some of these examples:

"Ella le envió un regalo a Miguel.

She sent a present to Miguel."

In this example, why do you need the le if you already have Miguel. It reads to me literally as "she him sent a present to Miguel" and I suppose it feels like excessive and unnecessary additional language in an already clear sentence. Is it for emphasis? Por favor ayúdame a entender.

Hola Zoe
In Spanish it's very common to repeat the indirect object as you can see in this sentence. It actually sounds more natural to use both. Here's a lesson that explains this double usage. 
I hope it helps.
