Businesses screening incoming leads, orders or form submissions for proxy activity use IP2Proxy to check whether an IP address belongs to a VPN, a TOR exit node or a residential proxy before deciding what happens next. On its own, that lookup sits in the middle of a Zap, feeding a decision rather than sending anything to a customer, since nothing about the check itself reaches anyone directly.

Paired with Mobile Message, the lookup becomes useful in Zaps that end with a text. A new lead from Facebook Lead Ads, a paid order from Shopify or a form response from Google Forms can run through IP2Proxy first, so the SMS confirmation, receipt or follow up only goes out once the traffic behind it has been checked. The result is a text that only reaches someone once their IP address has been screened, rather than a message sent to every submission regardless of where it came from.
