# Gauge Your Einstein Send Time Optimization Data Quality

Check your Enterprise’s data quality score for insight about the engagement data that Einstein uses to predict optimal send times. Data quality scores for Einstein Send Time Optimization are generated at the Enterprise level only.

Each Enterprise’s data quality score for email is generated by analyzing the Enterprise’s engagement data. This analysis determines a send time coverage score and a data richness score. On the Einstein Send Time Optimization (STO) dashboard for mobile, the send time coverage score is replaced with a mobile send coverage score.

In general, to provide recommendations, Salesforce requires at least one engagement event, such as opens or clicks of a commercial email in the past 90 days. When you activate Einstein Send Time Optimization, existing data counts toward the 90 days.

- To determine the send time coverage score and mobile send coverage score, Einstein analyzes the number of hours in a week during which you have at least one send. When your sends are spread across more hours during the week, your send time coverage score is higher. When your sends happen during fewer hours, your send time coverage score is lower.
- To determine the data richness score, Einstein analyzes the amount and quality of engagement data that’s used to make predictions for each individual contact. Einstein analyzes only mobile send data to determine the mobile data richness score and only email send data to determine email data richness.

To find your data quality score, navigate to Einstein Send Time Optimization and view the dashboard. To see your scores and tips that can help raise your data quality score, click **Data Quality Score**.

Note Transactional sends and test sends are excluded when generating your data quality score.
