# Messaging

As the administrator, you can send messages to JMap users from JMap Admin. 

{% hint style="info" %}
The messages will be displayed in the user interface (JMap Pro applications only). 
{% endhint %}

Users who already have an active session will see the messages immediately. The other users will see the message the next time they log on. 

Messages can be used to inform users of service interruptions, for example. 

Messages will be displayed each time a user starts a new session, during the validity period of the message.
