If you’re a professional email marketer, e-commerce retailer or simply an Internet user, you know how important it is to understand the quality of your IP check score. These scores are used to detect fraudsters and protect against cyber fraud, which can cost businesses in both financial and reputational losses.

There are many IP reputation lookup tools available, but not all are created equal. Some are free and offer basic information, while others require a paid subscription to see more comprehensive data. The best tool for checking an IP reputation is one that uses a variety of sources and provides cross-referenced results to ensure accuracy and reliability.

IP Check Score: Evaluating the Trustworthiness of IP Addresses

A good place to start is Validity’s popular Sender Score service. This tool checks an IP address against multiple blacklists and other public data sources to determine its reputation. A score of 90 or higher means the IP is considered a low-risk sender, while 80 or lower is poor and may cause issues with your deliverability.

It is also important to note that an IP’s reputation can change over time, so it is crucial to monitor it regularly and compare results across multiple services. Additionally, it’s helpful to customize scoring settings and API inputs for your specific business needs to reduce false positives.

Finally, it is vital to consider the types of proxies and VPNs that can affect an IP’s reputation. Using advanced technologies to detect proxies and VPNs can drastically improve the accuracy of an IP reputation check.
