This can be done straight from the Dashboard or Partner Dashboard through the message buttons. From the dashboards, you can message all users impacted by the information presented in the different widgets – for example: impacted by an alert.
You can also go to the Aperçu de la sécurité and, from the map, target people and facilities on the map via the Quick Selector. See the guide here. Ultimately, you can also message users via the Communication Module.
Also, the Admin can send out messages to specific end-users based on where they are now, are heading, etc., via the Communication Module of the Web Portal. When entering a new country, the end-user will also receive a welcome message with links to in-depth country information.
