Anthony has over 500 forms opened but not submitted over the past 90 days. According to LinkedIn, does he have enough to begin building a retargeting audience?

No, Anthony does not have enough to begin building a retargeting audience based on LinkedIn's requirements. LinkedIn's Matched Audiences feature requires a minimum of 300 unique users to be eligible for retargeting. While Anthony has over 500 forms opened, this does not equate to 500 unique users. A single user could have opened multiple forms. Therefore, it's highly probable that the number of unique users is below the 300 threshold. "Yes" is incorrect because the quantity of forms doesn't guarantee the necessary unique user count. "I don't have enough information" is incorrect because the provided information, combined with LinkedIn's known audience minimums, is sufficient to determine that the unique user requirement is likely not met.
