Which report would you use to understand email deliverability issues?

The Non-deliverables and bounce report is essential for understanding email deliverability issues because it specifically focuses on the emails that did not reach their intended recipients. This report provides insights into two critical metrics: non-deliverables, which are emails not delivered due to invalid addresses or technical issues, and bounces, which indicate temporary or permanent failures in delivering emails.

By analyzing this report, marketers can identify problems with their email lists, such as outdated or invalid addresses, and can take corrective actions to improve their overall email deliverability. Understanding these metrics is vital for optimizing campaigns, as high bounce rates and numerous non-deliverables can negatively impact sender reputation and future email deliverability.

The other reports mentioned, while valuable for different aspects of email marketing, do not specifically target deliverability issues. The engagement report focuses on how recipients interact with emails, the campaign performance report assesses overall campaign success metrics, and the open rate report examines how many recipients opened the email without addressing the underlying issues that may prevent successful delivery in the first place.
