Unless you have to satisfy some teacher or specific reader who has outmoded ideas about formality-- anything that is correct in the spoken language is acceptable in writing.
Receive is by no stretch of the imagination any better or more proper or more "correct" than get.
Not in AE the way I speak and write it, and have taught it at the university level. The "wall" between the formal and the colloquial is a thing of the distant past-- the century before last, for crying out loud!
So what you have to know is-- are you writing for someone who is still an adherent of obsolescent modes of style? If so, adapt your writing to appease such people. If not, "speak on the page" as you would anywhere else.
