Recipients
Roles are emailed: everyone with the role gets the message.slack("channel") posts to a Slack channel through an incoming webhook that an admin adds in the project’s Slack settings, so the webhook URL never lives in your code.
Notices wait about twenty seconds before they go out, so a burst arrives as one message listing the items, each with a link.
