How to make array values line by line while using in notification?

[KM SN]

I am triggering notification through event where I am passing  array as PARAM but they were coming as one after one in notification but expectation is one in one line. I tried with below code but not working? 

var multiplePersona = [];

    var persona = new GlideRecord("u_user_persona");

    persona.addQuery("u_sub_practice", 'CONTAINS', current.sys_id);

    persona.query();

    while (persona.next()) {

        multiplePersona.push(persona.getValue('u_name').toString());

    }

   // gs.log('user persona list ' + multiplePersona);

        var valueString = multiplePersona.join("\n");

        gs.log('user persona list ' + valueString);

        gs.eventQueue("user.persona.changed", current, valueString);

Is it that you are trying to print a list of persona's in a notification but instead of a comma separated list you want to show the 1 persona per line?

Exactly @Brian Lancaster  that's what I am trying for.

Pass it as a comma spirited array when you call the event. Then use a mail script to print them in the email line by line. In your notification it to call a mail script your do ${mail_script:scriptname}

Your mail script should look something like this. This is based off your current code already having the display value rather then the sys_id.

(function runMailScript( /* GlideRecord */ current, /* TemplatePrinter */ template,
    /* Optional EmailOutbound */
    email, /* Optional GlideRecord */ email_action,
    /* Optional GlideRecord */
    event) {

    // Add your code here
    var Persona = event.parm1.toString().splite(",");
    for (var i = 0; i < Persona.length; i++) {
        template.print(Persona[i] + "</br>"); //use /br instead of \n becasue it is a new line in HTML in a notification
    }

})(current, template, email, email_action, event);

@KM SN Ideally, you should handle this inside the email script and not via the script from where the event is triggered.
