Key metrics that can be negatively impacted by not segmenting your data include:
1. Open Rates: Generic subject lines and content are less likely to capture the attention of your subscribers. 2. Click-Through Rates: If your content does not resonate with the audience, they are less likely to click on any links within the email. 3. Conversion Rates: Poorly segmented emails are less likely to convert subscribers into customers, as the content may not be relevant to their needs. 4. Bounce Rates: Sending irrelevant emails can lead to higher bounce rates, as subscribers may provide incorrect email addresses to avoid unwanted content.
