Where: This change applies to High Velocity Sales in Lightning Experience. High Velocity Sales is available as an add-on in Enterprise, Performance, and Unlimited editions.
Who: Users with the Use Inbox user permission, available with the High Velocity Sales or Inbox license.
How: To schedule an email, sales reps open the cadence step card and either click the envelope (1) or Send Email (2).
Reps then select Send Later in the email composer.
The rep then selects the date and time and clicks Schedule.
To let your reps manage scheduled emails, use Edit Page to add the Send Email Later - Pending List component to any object’s home page, including the Salesforce homepage.
Using that component, reps can reschedule, edit, or delete an already-scheduled email.
