+The *MailInvitationType* property controls which version of the SAP Sail Insight app will be targeted by tracking invitations sent out by e-mail.
+Two different Branch.io URL schemes exist for the Sail Insight app: sailinsight-app.sapsailing.com and sailinsight20-app.sapsailing.com.
+They can be selected by providing *SailInsight1* or *SailInsight2*, respectively, as the values for the property. If the property is
+set to *LEGACY*, no Branch.io link is used in the invitation at all. This mode should no longer be used as soon as the Branch.io-enabled
+iOS app has hit the store. If not provided, it will default to *SailInsight1*.

 Note that when you select to install an environment using the `USE_ENVIRONMENT` variable, any other variable that you specify in the user data, such as the `MONGODB_NAME` or `REPLICATION_CHANNEL` properties in the example above, these additional user data properties will override whatever comes from the environment specified by the `USE_ENVIRONMENT` parameter.
