* 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.
