use the Cc (carbon copy) field. aside from the To: you can also use Cc to write their email addresses there, separated by a comma. and they will all receive the same email. the only problem is that not only will they receive the email, they will also see the email addresses you wrote in the Cc field. if privacy is not that all important you can use Cc. but if it matters a lot, you should use Bcc. (blind carbon Copy) this will keep the email addresses private but they will still receive the same email you sent.
