Your calls may show as "Spam Likely" “Potential Spam” or with other negative flags or labels for many different reasons, and at times may even be unintentional. Most of the time, if a carrier analytics provider is intentionally applying SPAM tags across their network, it’s based upon indicators of poor consumer experience, such as: high call volume to low-intent data, low answer rates, short duration calls, unclear or abusive scripting, compliance misses, and consumer complaints. Poor ANI management is a major contributor to this problem. When your ANIs are overused, misapplied, and not optimized in your dialing, you greatly increase your odds that analytics providers will assign your numbers a poor reputation. In addition to “carrier-driven” flagging and labeling, there is also a large ecosystem of private apps on the market that label numbers based on user feedback and analytics. In addition, decision-making around flagging, blocking, and silencing calls is also increasingly occurring at the hardware/device level. Finally, every consumer in your database is an individual with their own preferences and expectations. Not meeting their expectations in the real-time moment of the dial can lead to negative outcomes. Test calls across devices do not necessarily indicate a “carrier-wide” problem and can yield different results. There is no system available that can show you what a consumer saw on his or her phone screen when you called them, only that person knows. Keep in mind that the analytics providers state that “spam labeling is dynamic for every phone call, not a static property of a phone number. Every call is analyzed based on historical and real-time data. Therefore, not every call from a phone number may have the same label, and the flag status is not a guarantee of future call labeling.” - ref Hiya Connect: Caller Reputation Guide and “Your phone number reputation isn’t static. It evolves based on call behavior and user feedback. Even a previously trusted number can be flagged if spoofed or misused.” - ref TNS: What is Phone Number Reputation
