To access the Bulk Email feature, click on the Admin section of your toolbar and select Bulk Email from the dropdown menu options.

At the Bulk Email screen you will see an interface that looks very similar to a standard email.  here you will be able to fill in all the fields with your information including the From, To, Subject and Body fields.  If you have a list of email addresses you can put them all in the To field as a semicolon seperated list.

Alternatively, you can select a group of users from the box on the right.  For example you could select Registered Users and your email would be sent to all registered users on your site.

You can also add attachments to your emails and use tokenized content for your emails to add an additional level of personlization.  These features will be covered in a future blog entry so check back soon.
