How does Audience Sizing (IC) select users for campaigns?

The correct approach for Audience Sizing (IC) in selecting users for campaigns involves identifying a small percentage of users who have a history of engagement. This method is effective because it focuses on individuals who are more likely to respond positively to marketing communication based on their previous interactions. By selecting actively engaged users, the campaign can maximize its effectiveness and improve overall response rates.

Engaged users tend to show a consistent interest in the brand or product, thereby increasing the likelihood of successful outcomes compared to a random selection of users. This targeted strategy leverages data insights to create more personalized and effective marketing efforts, enhancing user experience and driving desired results.

The other options do not effectively prioritize user engagement, which is crucial for the success of targeted campaigns. For instance, randomly selecting users does not account for their likelihood to engage, while targeting users who have opted out risks further alienating them. Including all users indiscriminately disregards the importance of engagement history, which can dilute the impact of the campaign.
