To send a mass email to all participants in Beanstack, you would download an "All Account Creators" report. From there, copy all of the email addresses in that column and then paste those into your preferred email provider (i.e. Constant Contact, MailChimp). Save that as your Beanstack list and then send an email as needed!
If you wanted to only write to the readers of a particular program, you would instead go to Reports > Program Specific Data > All Registered Readers. From there, you would download the report and copy/paste the email addresses per the instructions above.
