Optimize marketing email send time for individual contacts

You can optimize when a marketing email is sent to individual contacts based on their previous email engagement. Within a set time range, the email will be sent to each contact when they will be most likely to interact with it. 

Understand limitations and considerations

• You can set a sending range of up to 168 hours, or seven days. This applies to both emails sent immediately and those scheduled for later. 
• Contacts without enough engagement data will be sent the email at the beginning of the sending range.
• Sending time is calculated using your user's time zone.
