What aspect of the email delivery is NOT included in calculating Delivery Rate?

The Delivery Rate is a measure of the emails that successfully reach their destination in the recipient's inbox compared to the total number of emails sent. To calculate this rate, you focus on certain aspects of email delivery.

When emails are accepted at the gateway, they are counted as part of the successful delivery process. Emails that bounce, meaning they were not deliverable for some reason, are not included in the successful delivery metrics either, as they indicate that the email did not reach the intended recipient.

Emails opened are not part of the calculation for Delivery Rate; they are assessed in metrics related to engagement rather than delivery. The aspect that is specifically excluded from the Delivery Rate calculation is the emails sent to spam or junk folders. While these emails have technically been delivered to the recipient's mailbox, they are not reaching the primary inbox and are, therefore, not counted as successfully delivered as per the traditional definition of Delivery Rate.

Thus, when determining what aspect is not included in calculating Delivery Rate, it is the emails that land in spam or junk folders that are set apart since they do not constitute successful delivery in the primary sense of reaching the target audience.
