Calculating CES involves aggregating multiple engagement metrics. Here are some common components:
Open Rate: The percentage of recipients who open your email. Click-Through Rate (CTR): The percentage of recipients who click on links within your email. Conversion Rate: The percentage of recipients who take a desired action after clicking through your email. Unsubscribe Rate: The percentage of recipients who unsubscribe from your mailing list. Bounce Rate: The percentage of emails that could not be delivered to the recipient's inbox.
To calculate the CES, you can assign different weights to these metrics based on their importance to your business goals and then combine them into a single score.
