Add Send Properties

Using the the Smarty utility addSendProperties you are able to add key/value pairs to the properties object of any system event related to the message contact ID (open, click, bounce, etc.).

{$utils->addSendProperties(["foo"=>"bar","foo2"=>"bar2"])}

The above example will add the key/values pairs to the properties object of the system event:

"properties":{
  "foo":"bar",
  "foo2":"bar2"
}

 You may also add a dynamic value to the properties object:

{$dynamicValue = 'biz'}
{$utils->addSendProperties(["foo"=>"bar","dynamicValue"=>{$dynamicValue}])}

The above example will add a the key/values pairs to the properties object of the system event (where dynamicValue is "biz"):

"properties":{
  "foo":"bar",
  "dynamicValue":"biz"
}

Note that send properties can be rendered in a message the getEventRecords method, they are not available for searching contacts using audience rules.
