Work on your email templates
Within email you have a handful of templates for newsletters, etc. They are not the most user friendly to customize. Once a user has gone to the trouble of customizing an email, provide them with a way to save it as a template. Additionally, create the functionality to revert sent messages into draft form so they can be used as a form of template- i.e. if someone else in my organization sent something, I can take it and reopen it as a draft in my email, and use all their same formatting/color choices, etc.

Also the ability, to create and save your own html templates. We currently Use PHPlist for all of our email parent communications and will not migrate to using Blackboard because of this.

A template "wizard" or a template editor similar to constant contact, mailchimp or other similar services would be amazing!
