To measure customer churn in email marketing, you can track several key metrics:
Unsubscribe Rate: The percentage of subscribers who opt-out of your email list over a specific period. Open Rate: The percentage of recipients who open your emails. A declining open rate can indicate potential churn. Click-Through Rate (CTR): The percentage of recipients who click on links within your emails. A drop in CTR can also signal churn. Engagement Rate: Combining open and click-through rates to get a comprehensive view of subscriber engagement.
