And/Or Logic in Trigger and Filter Constraints
Issue
How "And/Or" logic is applied to constraints in Smart List filters and triggers.
Solution
In Smart List filters, additional constraints act as "and" logic.
Example:
Was Sent: [this email asset] between this date range min number of times: 2
will function as
Was Sent: [this email asset]
-and-
between this date range
-and-
min number of times: 2
When you have multiple values inside a single constraint, that is "or" logic.
Was Sent: [this email asset OR that email asset]
There is not a way to change the logic of constraints, so if you wish to have some sort of 'Or' between constraints then you would have to use multiple filters with 'OR logic between them.
