I'm trying to send a newsletter with PHPMailer meanwhile protecting my customers privacy.

At first I set the receiver configuration with `mail->addAddress('customerEmail']);` but I found out that sending it this way, every receiver could see other customer's subscribers E-mail addresses.
I changed the `addAddress` to `mail->addBCC('customerEmail']);` so that it doesn't show every E-Mail address (in fact now it even doesn't show the recipient E-mail address of the customer it's being send to), but this way if anyone wanted to reply to the E-mail, their response would also be sent to the rest of the subscribers...

What is for you the best option to face this problem?
