Send windows

Overview

For segment triggered flows, if you want your flow to send as soon as data refreshes you can choose send immediately when segment updates when creating your flow.

However, if you want to avoid sending during certain hours, e.g. during the night, you can specify a specific window during which flows will send. You actually accomplish this by specifying the only time you do want messages to send. During this send window, any time the data refreshes, your flow will send again during that time period.

For example, if you set a send window to 3-9 PM, any time the flow data refreshes within those 6 hours, your triggered message will send. However, even if the data refreshes at 9:30 PM, the message won't send again until that send window opens up at 3 PM the next day, and only if the receiver is still a member of the segment.

Data pipes, loads, and send times

This diagram illustrates how data pipes and loads affect send time within a set send window.

6 hour increments

Send windows must be six hours at minimum. For windows less than six hours, use a send time, which has a two hour send window on its own.
