Let us presume that it is alright to drop the preposition so that grammatical propriety should allow you to express
Then you would have to solve the problem of ambiguity. Inspect the following cases.
Send me there.
- Send {object} to {destination}.
Send it a kill signal.
- Send {destination} {object}.
- I asked my colleague to send a hung process a kill-signal to terminate it.
Send him me.
- {Send him to me}?
- Or, {Send to him, me} ?
Then, let's look at the following progression.
- Send me {the document}.
- Send me {it}.
- Send {the document} {my information}.
- Send {the document} {me}.
- Send it me.
However, your paralleling your English usage with German is not precise. The two grammatical situations are dissimilar.
While German retains the difference between accusative and dative, English does not. First, pardon my deficiency in German comprehension.
- Sie = nominative perpetrator
- es = accusative package
- mir = dative destination = implied to-me
Since each word is well-encapsulated, the order would not make a difference in the meaning:
- {verb} {perpetrator} {package} {destination}
- {verb} {package} {perpetrator} {destination}
- {verb} {package} {destination} {perpetrator}
- {package} {destination} {perpetrator} {verb}
Such that, due to the dative vs accusative attributes of each entity, the meaning stays the same whether you say it prosaically or awkwardly:
- {schicken Sie es mir}
- or {schicken Sie mir es}
- or even {schicken mir es Sie}
Whilst German has retained sufficient declension morphemes to allow it to be used synthetically in many case, English has devolved into mostly analytic usage where word proximity, order and context of the phrase has to be analysed for the meaning of a phrase.
Case in point
In English, we would not know if a pronoun is used datively or accusatively, which is the cause of the ambiguity. Which is why it is best for you to stick in the preposition, and conform to the principle of proximity:
- send to her his mail.
- send it to his mail.
- send it from his mail.
- send to his mail to her.
