To evaluate the health of your email list, consider the following metrics:
Open Rate: The percentage of subscribers who open your emails. Click-Through Rate (CTR): The percentage of subscribers who click on links within your emails. Bounce Rate: The percentage of emails that cannot be delivered. High bounce rates indicate outdated or invalid email addresses. Unsubscribe Rate: The percentage of subscribers who opt out of your list. A low rate indicates good list health. Spam Complaints: The number of subscribers who mark your emails as spam. High complaints can harm your reputation.
