Why is it Important to Identify and Remove Duplicates?
Identifying and removing duplicates in
email marketing campaigns is critical for maintaining a clean and efficient email list. Duplicates can lead to multiple emails being sent to the same recipient, which can be annoying and result in higher unsubscribe rates. Additionally, it can skew your campaign analytics, making it difficult to accurately measure your performance metrics such as open rates, click-through rates, and conversions.
How Do Duplicates Affect Deliverability and Engagement?
Sending multiple emails to the same address can negatively impact your sender reputation. Email service providers (ESPs) like Gmail and Yahoo may flag your emails as spam, which can lower your
deliverability rates. Moreover, recipients who receive duplicate emails are less likely to engage with your content, leading to lower engagement metrics and potential loss of subscribers.
