Send List Emails at the Ideal Time
Reps can now schedule when to send a list email. Choose an ideal date
and time to ensure that the list email has the best chance of being read. For example,
schedule a list email to arrive at the beginning of the work day. Scheduling was previously
available for individual emails only.
