In order to send out a mass email using the correspondence report, you have to have Microsoft Outlook installed on your computer. If you don't have Outlook, you can use the "Copy Email" button at the bottom of the Correspondence Report window. This will copy all of the email addresses from the report. When you paste the emails, make sure that you do it in the BCC line. This will ensure that your patients can't see each other's email addresses Keep in mind that your email client may have a restriction on how many emails you can send at one time.
