They are like little doodles in the text. They don't convey any more information than is already in there. Things which are urgent are generally best written with as little adornment as possible. If someone isn't already for the cause it can cause them to not take your writing seriously. Imagine if you're the parent of a child and they send you this message: > "Active shooter at school " The time taken to get the emoji undercut the seriousness of the message. They are apparently trying to communicate something important but deliberately wasting my time.
