STO Recurring delivery

@srushti_1, If you're looking for something to optimize the delivery in ACS follow this documentation https://experienceleague.adobe.com/docs/campaign-standard/using/testing-and-sending/scheduling-messages/optimizing-the-sending-time.html?lang=en

If you're looking to do something on Predictive user engagement capabilities in ACS follow this documentation,

https://experienceleague.adobe.com/docs/campaign-standard/using/testing-and-sending/preparing-and-testing-messages/predictive.html?lang=en

And a small correction from Abhi's suggestion there's no continuous delivery in ACS. All you will have is either a single send or recurring delivery.
