Messaging Service Notifications

The Messaging Service Notifications - for Slack & MS Teams - deliver deliver information based on the Daily Summary Mail.

In addition, notifications can be sent for changes in alert level.

Message content

Messages are sent on a per-vessel basis. There are two message types:

  • Interval-based: Messages for target vessels are sent at the specified time interval
  • Condition-based: Current alert levels are compared to the previous alert level, and if a change has occurred, a message is sent
