Even adding <!everyone> in the message doesn't push it to the users phones. Has anyone else been able to do this or could anyone tell me what I'm doing wrong?
--- EXAMPLE --
curl -X POST --data-urlencode payload={"parse": "full", "channel": "#alerts", "username": "monitor-1.state.company.local", "text": "<!everyone> lets see if i get this on my phone", "icon_emoji": ":sos:"} https://example.slack.com/services/hooks/incoming-webhook?token=xxxxxxxxxxxxxx
