How Can I Use Metrics to Identify and Remove Inactive or Unengaged Email Subscribers?

Email marketing remains one of the most effective channels for reaching and engaging with your audience. However, to maintain its efficacy, it’s crucial to keep your email list clean and targeted. One of the most common issues marketers face is dealing with inactive or unengaged subscribers. These are contacts who no longer interact with your emails, which can negatively impact your deliverability, open rates, and overall campaign performance. In this blog post, we’ll explore how to use metrics to identify and remove these inactive or unengaged email subscribers, ensuring your email marketing strategy remains effective and efficient.

Understanding Email Engagement Metrics

Before diving into how to identify and remove inactive subscribers, it’s important to understand the key metrics that reflect subscriber engagement. These metrics will help you gauge the health of your email list and pinpoint those who are no longer active.

Bounce Rate
