Email marketing agencies measure the success of campaigns using various key performance indicators (KPIs). Some common KPIs include:
Open Rate: The percentage of recipients who open the email. Click-Through Rate (CTR): The percentage of recipients who click on links within the email. Conversion Rate: The percentage of recipients who take the desired action (e.g., making a purchase). Bounce Rate: The percentage of emails that were not delivered successfully. Unsubscribe Rate: The percentage of recipients who opt-out of the email list.
By analyzing these metrics, agencies can optimize future campaigns to improve performance.
