How does Send Time Optimization work?

Send Time Optimization looks at the actions below for each recipient in the following order to determine the best send time: 

1. Most Recurring click time
   • The hour in which the recipient has registered the most clicks
2. Most recurring open time
   • The hour in which the recipient has registered the most opens
3. Most recurring click time for the account
   • On average, the hour in which all recipients in your account register the most clicks
4. Specified date and send time
   • The date and time that was selected when setting up your email campaign

The formula collects click/open time starting at the bottom half of every hour for 24 hours. For example, if a recipient's data shows that they click the most links between 1:30 and 2:29 PM, then STO will send their campaign at 2:00 PM.
