Several key metrics should be closely monitored during an investigation:
Open Rate: The percentage of recipients who open your email. Low open rates may indicate issues with your subject lines or sender reputation. Click-Through Rate (CTR): The percentage of recipients who click on links within your email. A low CTR suggests that your content might not be engaging or relevant. Bounce Rate: The percentage of emails that cannot be delivered. High bounce rates can harm your sender reputation. Conversion Rate: The percentage of recipients who complete the desired action, such as making a purchase or filling out a form. This metric directly impacts your ROI. Unsubscribe Rate: The percentage of recipients who opt out of your mailing list. High unsubscribe rates can indicate that your content is not resonating with your audience.
