There's a balance. Like the example the OP gave is abysmal. I do not want that. Have one or two actual sentences and send it, if we're in an actual live conversation. If you can't type that fast enough, take a typing course.
If we're not actively talking, write the whole damn paragraph before you send it! One thing I really dislike is:
> Hey, how's going? > Can I ask you a question on $TOPIC?Will not get an answer from me. Well maybe once, if we've never talked before and that will be along the lines of "just go ahead and ask, don't bother with the chit chat". Most people 'get' this nowadays but there are some hold-outs. I suppose the hold-outs might be more numerous in non-tech companies or in the non-tech departments of those companies.
