University policy applies if you want to send a message to ALL members of one or more of the following groups:
For a mailing to one or more of these groups, use our Send Email to a Pre-Defined Group article.
If you need to send a message to some other large group (not all students, all staff, etc.), do not send it as you would a regular email (that is, from your email address, with all recipients listed under To, CC, or BCC).
- You'd have to enter ALL those email addresses into your mail client.
- You'd cause a sudden (and potentially disruptive) spike in network traffic.
- You might run afoul of university policy. (See University Policy 5.2, Mass Electronic Mailing.)
Instead, send your message from an announcement e-list, as described in our Send Email to a List of Addresses article.
