Model Refresh Frequency:
Einstein Engagement Frequency's predictive model needs to be updated regularly to reflect the most recent engagement patterns.
Daily Refresh:
The EEF model is refreshed daily. This ensures that the send frequency recommendations are based on relatively up-to-date data.
Why Not Other Options:
A . Hourly: Hourly refresh would be computationally intensive and unnecessary, as engagement patterns don't change that rapidly.
C . Monthly: Monthly refresh would be too infrequent, as the model's accuracy would degrade significantly over a month.
D . Biweekly: Biweekly is also too infrequent to keep the model aligned with recent engagement trends.
In Summary:
The Einstein Engagement Frequency model is refreshed B. Daily to maintain accuracy.
