In my experience, being able to choose the correct type of communication is an essential skill for this type of position. If I need to discuss something that is more time sensitive, I may not want to communicate through email because responses take time to go back and forth. I may instead choose to call the person and simply follow up with an email to summarize and document any important information that was discussed during the phone call. This allows the person to acknowledge the key points of discussion, accept any plan of action, or correct me if I misunderstood something.
Text messaging can also be a time saver, but I would only use this for casual check-ins, not formal discussions. Something text-worthy (for me) is something that either doesn't require a response or can be answered by the recipient with a short response. For lengthy conversations or important discussion, I always feel face-to-face is best. Too much can get misconstrued over text, email, and sometimes telephone interactions. I certainly agree that people receive messages and respond differently in an electronic/cyber space than they do in physical spaces, so we must use our best judgment to choose the best type of communication for each interaction and to achieve the desired outcome.
