The Newsletters feature enables broadcast email (newsletters) capabilities. The feature allows communications to be created in advance and scheduled for delivery. The Newsletter feature also allows new newsletters to be created from existing ones.
While it is possible to send newsletters from the staging environment, it is not recommended for the following reasons:
The newsletter unsubscribe feature will not work on the stage site.
If the newsletter is integrated with a dynamic form that is populating an email list, the list should exist in production.
Always send email communications to real constituents from the production environment.
Before a newsletter can be saved there must be at least one existing email list. It is recommended that email lists be kept and newsletters sent from the production environment because access can be limited to the production environment, an added measure of security.
Best practices suggest that a Test list is created and that a test mail is sent to this list prior to sending a broadcast email to a large number of email addresses. Ideally, several people will receive the test mail to review.
