ISP Targeting
ISPs can be used to target any traffic that comes from a specific Internet Service Provider, for example, AT&T, Optimum, Frontier Communications, and more. This targeting can be particularly useful when ISPs are targeting potential customers who currently subscribe to a competitor's ISP. It can also be helpful for an ISP to anti-target (exclude) all traffic coming from their own ISP (as these are existing customers).
1. Within the Targeting tab of the Campaign Builder, the Targeting grid appears. Click on the 
sign against each row or object to add in its targeting rules.
