If anyone else has issues using yahoo change the port to 587 that solved my issues.

also see below for correct placement

Notifications.PlaySound(Path.Combine(windowsFolder, "Media", "tada.wav"));                   

>>>Notifications.SendEmail("fx.alert@yahoo.com.au", "fx.alert@yahoo.com.au", "Price Alert", "TRIGGERED");

 triggered = true;

Is it possible to add an email notification to the indicator?

I found this but cant figure out where to place it:

Notifications.SendEmail("***@yahoo.com.au", "***@yhaoo.com.au", "Price Alert", "TRIGGERED");

Have tried a couple of locations in the code namely:

line after:

 Notifications.PlaySound(Path.Combine(windowsFolder, "Media", "tada.wav"));

and 

at the end of 

  public override void Calculate(int index)
        {
            if (triggered)
            {
                PlayedNotificationLine[index] = Price;
                return;

either place i get a failed to send email in the log.

settings are correct as ctrader sends emails on open and close of trades, just cant get it to send with this indicator
