I have a function:
`function sendEmail($id,$email) {

$mailer = acymailing_get('helper.mailer');
$mailer->report = true; //set it to true or false if you want Acy to display a confirmation message or not (message successfully sent to...)
$mailer->trackEmail = true; //set it to true or false if you want Acy to track the message or not (it will be inserted in the statistics table)
$mailer->autoAddUser = false; //set it to true if you want Acy to automatically create the user if it does not exist in AcyMailing
//$mailer->addParam('var1','Value of the variable 1'); //Acy will automatically replace the tag {var1} by the value specified in the second parameter... you can use this function several times to replace tags in your message.
$mailer->sendOne($id,$email); //The first parameter is the ID of the Newsletter you want to send or its namekey

It's working okay and sending email but when I execute it i have Joomla Message come out like this.

Is there a way to disable showing this messages or maybe to overwrite them with my own?
