Duplicate records can significantly impact the effectiveness of your email marketing campaigns. Here are some key issues:
Increased Costs: Many email marketing platforms charge based on the number of contacts. Duplicate records inflate your list size, leading to higher costs. Decreased Deliverability: Sending multiple emails to the same recipient can result in higher bounce rates and spam complaints, which can negatively affect your sender reputation. Inaccurate Analytics: Duplicate records can skew your metrics, making it difficult to accurately assess the performance of your campaigns. Poor User Experience: Receiving multiple copies of the same email can frustrate your subscribers, leading to higher unsubscribe rates.
