Hi.     

I have a lot of child business units handling marketing sends on country levels. All of these child business units have Einstein STO turned on. Some links in the mails sent on child business unit level have certain tracking aliases. I monitor clicks on these tracking aliases, and if I notice a subscriber clicking on these links I send an email from the parent business unit to the subscriber exploring the content of the clicked link further. The Einstein STO dashboard informs: 'Einstein analyzes the past 90 days of email engagement history for email addresses in this enterprise account with the Commercial send classification.' So, I'm assuming I could actually benefit from sending the mail from the parent business unit to the subscriber using STO though it might be the first send from the parent business unit to that subscriber as Einstein analyzes email engagement history for my entire enterprise account.. right? Thank you   #Einstein Send Time Optimization #Email Marketing #Marketing Cloud
