What configuration should a marketer use for a summer sale email campaign based on customer browsing history?

For a summer sale email campaign that leverages customer browsing history, the appropriate configuration involves targeting customers who have opted into receiving emails and who have shown interest in relevant products recently. In this case, selecting those who have opted in and have browsed products in the last 90 days is effective. This timeframe captures customers' recent interests, allowing the marketing team to engage with users who are likely still influenced by their browsing activity.

Selecting an appropriate timeframe like the last 90 days ensures that the marketer is reaching out to customers while their interests in specific products—and the seasonal relevance of a summer sale—are still fresh. This approach maximizes the chances of conversion since it targets individuals who have recently engaged with the material, thereby increasing the likelihood that they will be interested in the upcoming sale.

This option aligns with best practices for email marketing: respecting customer preferences (by ensuring they have opted in) while utilizing data-driven insights (browsing history) to tailor the campaign effectively.
