Einstein Send Time Optimization for Journey Builder
Einstein Send Time Optimization (STO) uses machine learning and 90 days of email or push notification engagement data to determine the best time within the next 24 hours to send a message to each contact. Include the Einstein STO activity in a journey immediately before an email or push notification activity to reach contacts when they’re most likely to engage. Or preview Einstein’s optimal send times for a data extension before you send. To use this activity, activate Einstein Send Time Optimization for your business unit.
