Email has a place. I always let my teams know that text, phone call, or IM / DM aren't professional ways to communicate.
The reason being is that it isn't externally travelable - you can't send it to the next recipient in a format that is accepted by most people.
Also I hate needing to check five or seven fucking messaging apps to get all of the info consolidated. Send a goddamned email with everything once the thought is finished.
