The term "pause" refers to a type of step that can be incorporated into your automation (a.k.a. drip campaign).
The Pause step sets a wait time between steps. Pauses are used to prevent the included campaigns in an automation from sending back to back or to manage the length of time between emails/ flag events, etc.
You have the option of selecting hours, days or weeks.
Simply drag the pause over to the desired space in your automation workflow and click the pencil icon to set the amount of hours, days or weeks to pause.
1. Automation timing uses the original scheduled time of the kickoff email (or event) to determine send times / step evaluation for subsequent steps and campaigns.
2. In theory, when a kickoff email is sent at 9 am, then the automation pauses for a week, and and second email is sent, email #2 will also send at 9 am. The exact timing is determined by the timestamp of the receiving server in the previous step in the automation. In some cases you may see slight diversion.
