Keep Track of List Emails in the Activity Timeline

For your sales reps, the activity timeline rules the screen. Now the timeline shows an activity when a list email has been sent to a lead or contact. This change applies to Lightning Experience only.
The activity timeline filter

List email activities only appear in the activity timeline if logging list email activities is on. It is turned on by default.

Your reps can’t create a list email in Salesforce1, but they can still see the activity.
Note

Note

In Salesforce Classic, mass emails are logged as tasks, not activities. They are logged in plain text (even for HTML emails), don’t include attachments, and don’t display recipients.
