How Do Duplicate Entries Affect Email Marketing Campaigns?
Duplicate entries can significantly impact your email deliverability and reputation. They can cause multiple issues such as:
Increased Costs: Sending emails to duplicate addresses inflates your costs, especially if you are using a paid email service provider (ESP). Skewed Analytics: Duplicate entries can distort metrics such as open rates, click-through rates, and conversions, making it difficult to measure campaign success accurately. Poor Customer Experience: Recipients might get annoyed if they receive the same email multiple times, leading to higher unsubscribe rates and complaints. Reputation Damage: Internet Service Providers (ISPs) may flag your emails as spam if they detect multiple emails sent to the same address, harming your sender reputation.
