Create an email, give it a meaningful title, and select the list of recipients. You can save everything as a template for later, or send it immediately.
Email addresses may be contributed by plugins (such as a newsletter), and duplicates are removed when the mail is sent
Any attachment is selected from the list of valid downloads.
Mail may be sent as plain text (most universal, and least at risk of being classed as spam), or as HTML (in which case a plain text alternative is automatically generated). The theme style may optionally be added to the email. Alternatively, a predefined template can be selected.
