CRM systems include campaign performance analysis features that allow organizations to measure the success of marketing campaigns, such as conversion rates, customer responses, ROI, and overall effectiveness. This enables continuous improvement of marketing strategies.
Option A: Message delivery tracking only shows if communication reached the customer, not campaign success.
Option B: Contact response summaries are part of reporting but do not give full performance insights.
Option C: Promotion strategy evaluation is broader and more subjective than measurable campaign analytics.
Therefore, the correct CRM feature is campaign performance analysis.
