Targeting the right audience is crucial for several reasons: 1. Higher Engagement: Sending emails to interested recipients increases open rates, click-through rates, and overall engagement. 2. Better ROI: A well-targeted email campaign is more likely to convert, leading to a better return on investment. 3. Brand Loyalty: Relevant and personalized emails can improve customer satisfaction and loyalty. 4. Avoiding Spam Filters: Sending emails to uninterested recipients can lead to spam complaints, which can affect your sender reputation and deliverability rates.
