Sendinblue's reporting and analytics have some limitations. For example, the dashboard interface may be overwhelming for beginners and lacks advanced reporting capabilities for more complex data analysis. Additionally, some users have reported inconsistencies in the reporting data, which can be frustrating for businesses that rely on accurate analytics to make important decisions. However, Sendinblue's reporting and analytics are still quite comprehensive and provide valuable insights into email performance metrics, such as open, click-through, and conversion rates.
