Field	Value
For each customer in segment	Any Customer applies this constraint to all customers. Segment limits the rule to customers in the segment you select.
the number of duplicate offers from the channel	Any Channel specifies that Optimize consider offers from all channels. Channel name limits the rule to offers from the channel you specify.
over the time period	A time period you specify applies the rule to all time periods with the specified duration. The duration is a number of days. In other words, the rule must be true for any time period specified. For example, if you create a rule that says a maximum of 3 offers can be sent to any customer in a 30-day period, Optimize will not allow any optimized offers (also considering offers already given in contact history) to exceed 3 in any 30-day window. This "sliding window" interpretation of the time period allows you to truly control your offer presentation strategy. 0 represents “this optimization period” and sets the minimum and maximum number of offers made over the entire time range for proposed contacts across all participating campaigns in this Optimize session (that is, between the earliest and latest proposed dates in the PCT). When a value of zero is used, no sliding windows are used (The entire optimization period is considered as a single time window). In addition, contact history is not considered.
concerning offer/offer list	Any Offer specifies that Optimize consider all offers and offer lists. Offer/offer list limits the rule to the offer or offer list you select. Offer Versions limits the rule to offers containing the offer attribute value(s) you specify in the query builder, including parameterized offer attributes.
should not exceed	Limits the maximum number of duplicate offers (that can be sent to each customer) to the value you enter. If you set this value to one, the customer receives at most two—or, one duplicate—of the same offer. Use zero to eliminate the possibility of duplicate offers.

“For each customer in segment Any Customer, the number of duplicate offers from the channel Any Channel over the time period 90 days concerning offer/offer list Brokerage Product = free consultation should not exceed 2.” This rule allows no more than three of the free consultation Brokerage Product offers (one original and two duplicates) to appear within the optimized contact list for each customer in any 90-day period.
