What does the Deliverability Rate measure?

The Deliverability Rate is a key metric that evaluates the effectiveness of email campaigns in reaching recipients' inboxes. Specifically, it measures the proportion of emails that were successfully delivered to the inboxes of the recipients compared to the total number of emails that were sent. A high deliverability rate indicates that the majority of emails are reaching their intended destination, which is essential for successful email marketing.

This metric is crucial for marketers, as it helps them understand how well their emails are being received and whether they are facing issues such as bounces or being filtered into spam folders.

Other options do not adequately define the Deliverability Rate. For instance, while metrics related to domain usage, recipient engagement, and spam reports are essential in the broader context of email performance, they do not specifically address the success of emails being delivered to inboxes, which is the core aspect of the Deliverability Rate.
