Mass E-mail question

[4kidz]

Does anyone know if I send out an e-mail from my admin panel and I click on all customers will all the customers be able to see each others e-mail addresses? I want to send out a holiday e-mail offering a discount coupon but I don't want to have to send individual e-mails but want to make sure that all the e-mail addresses are not visible.
thank you for your help.
