Emma: Comparison of mass-email solutions
There are several methods you can use to email a group of users regularly. But not all methods work in the same way or offer the same features. Use the information below to determine what solution works best for your needs.
Exchange Online
Exchange Online (a feature of Office 365) supports "distribution lists" (or groups). Members of these groups are other Duke Office 365 users. Transport of the message remains in Office 365. The owners and members can be modified using Outlook on the Web.
Sympa Mailing Lists
Sympa is Duke's email mailing list system. You can create, join and manage email lists to connect to communities or groups at Duke. You can also add members outside of Duke. Groups can be private, public, or moderated for discussions or announcements. Membership is not limited to Duke users. You can also use Sympa to create a general contact address for your department or program.
Emma Mass Email
Emma is a bulk email service that can contain Duke groups (populated manually or automatically, then synced to Emma). Emma provides a robust editor for composing professional messages including offering templates with Duke branding. And after the mailing, Emma provides reports that let you know how many read your message and even which links in a message were clicked.
