When creating a triggered campaign you have options for scheduling that campaign to go live in step 6 of the setup process. Included in your scheduling options are advanced settings to further control when the trigger will send based on hours of the day and days of the week. Locate these additional settings under "How frequently do you want the trigger to run", seen below:
1. If you choose to check for recipients in hours, you will also select the hours of the day. This is an optional setting that will allow you to control what hours of the day the trigger can send. Typical use case would be to only send during business hours. If you do not wish to limit the window, leave the hours boxes blank.
2. When you choose to check for recipients in either hours or days, you will also select the days of the week. This is an optional setting that will allow you to control which days of the week the trigger can send. Again, typical use case is to send on business days. If you do not wish to limit days of the week, leave "All Days" selected.
If a recipient falls into the trigger segment in an off window, meaning that they met the criteria at an hour and/or day outside of what is configured, they will be held until the next valid window. For instance, if a recipient falls into the segment on a weekend, but the trigger is setup to run only on weekdays, the recipient will be picked up on Monday when the trigger runs at it's scheduled time.
