You can build the campaign to receive X visitors every Y time.

For example, you want to have 100 Visits every 24 hours for 7 days,

The formula will be:

Quantity: 100

Runs ( Total orders to be sent): 7

Interval (Break between each run, In minutes): 1440

As result, an Order of 100 Quantity, will be sent every 1440 minutes (24 hours), 7 times total.

This means You will get a total of 700 Visits in 7 Days. 100 Visits per day.
