Adding link to PHPMailer email

[NotionCommotion]

I am sending emails using PHPMailer.  My configuration is below.

 

When adding a link to the message, should I use anchor tags?  Both seem to work.  What is the implication to recipients who are not using HTML email?

 

On a side note, if anything below seems wrong, please let me know.

 

Thanks

$msg='<p>Hello</p><p>Link: http://phpmailer.worxware.com/</p><p>Link: http://phpmailer.worxware.com</p><a href="http://phpmailer.worxware.com">http://phpmailer.worxware.com</a>';

$mail = new myPHPMailer(true);
$mail->AddReplyTo('myEmail@xxx.com', 'Michael Reed');
$mail->SetFrom('myEmail@xxx.com', 'Michael Reed');
$mail->AddAddress('johndoe@xxx.com', 'John Doe');
$mail->Subject = "Here is your email";
//AltBody property need not be sent since PHPMailer will create an alternate automatically
$mail->MsgHTML($message);
return ($mail->Send());

class myPHPMailer extends PHPMailer {
    public function __construct($allow_exceptions=false){
        $this->isSMTP();
        $this->SMTPDebug = 0;
        $this->Host = "smtp.gmail.com";
        $this->Port = 587;
        $this->SMTPSecure='tls';  // sets the prefix to the server.  Used for gmail only.
        $this->SMTPAuth = true;
        $this->Username = 'xxx';
        $this->Password = 'xxx';
    }
}
