One of the benefits of Retreva is the schedule is set for you. Retreva calculates the time between emails and considers factors such as time of day, day of the week, and holidays.
If you need to send an email to contacts outside of the schedule, you can use our “One-Time” message feature found on the contacts page. Or use Conversation from the Action drop-down in the Contact view.
If you need to stop campaign emails you can make your campaign pending at any time by clicking on the campaign tab and click on the “Make Pending” button or adding the appropriate dates under Campaign Block Dates.
