Email Classes

The Faculty Dashboard's class email feature plugs all of the students' email addresses into the Bcc line of your email. (It uses the Bcc field so that each student receives the email without seeing the other students' email addresses.) For most classes, the email feature works without problems. However, the programming assumes a maximum of 3000 characters in the Bcc field. If you exceed 3000 characters, you will encounter problems.

Problems with Large Classes

How many student addresses can the Bcc line hold? The number varies because student email addresses vary in length, but the "safe" address limit is 142. (The maximum length of a UofM email address with a semi-colon delimiter is 21 characters. 3000 / 21 = 142 and change.) So, you should be able to email a class of up to 142 students without a problem because you will not hit the 3000-character limit. If you have more than 142 students, you might run into problems. If so, you have the options, outlined in Methods 2 and 3 below.

Method 1: Emailing Most Classes through the Faculty Dashboard

Your semester's classes are listed in your Faculty Dashboard portlet; click on the envelope icon next to the class you wish to email:

Faculty Dashboard - Click Envelope

This brings up your email screen. The email addresses of all of this class' students will appear in the Bcc field.


Type your own address in the To field to make sure that you will have a copy of the message; type your message, then Send.


Method 2: Emailing a Large Class through the Dashboard

Click the envelope icon by the class.

If your class is too large, you will see the Summary Class List page for the class, not the email screen.

Scroll down past the class roster on the Summary Class List. At the bottom of the screen you should see a large block of email addresses. Notice that there is no Email Class button, icon, or link: your class is too large to email automatically through the Dashboard:

Class List E-mail Listing

You have two options:

  1. Cancel your email attempt and proceed to Method 3 below (Recommended). OR,
  2. Proceed with your attempt to email the class, but in stages.

Proceeding with Method 2

In the Class List Email block, copy half of the addresses. (Make note of the last address selected.)

Open your UofM email. Paste copied block in the Bcc field of your email message.  Return to the Class Listing box, copy the remaining addresses, and paste them in the Bcc field. Then type your address in the To field, complete the Subject line, type your message, and click Send.


This method is not automatic and you have to be very careful about your copying and pasting. If you forget where to begin with your second copy effort, you may unintentionally omit some students from the Bcc field, and these students will not receive the message.

Method 3: Recommended Method for Large Classes

This is the most reliable method for emailing large classes. (Actually, you can email any class, regardless of size, using this method.)

  1. Open your UofM email and create a new message.

  2. In the To line, type in the class email ID in the format shown in this example:

    • Subject ID: The standard abbreviation for the subject area. Here, PSYC (for Psychology)
    • Course #: Here, 1200
    • Section #: Here, 001
    • A period
    • Year: Here, 2018
    • Semester Code: Here, F for Fall (Use U for Summer, S for Spring)

    The class email ID should not contain any spaces, and all letters must be in upper case.

  3. In the Cc or Bcc line, type your own email address to make sure that you will have a copy of what you send.

  4. Type your Subject and message, and then click Send.
