You could Attach-and-Hold multiple emails then use CorrSend to send them at a specific time.

Thanks PEDEL for your reply.

I still have a doubt here. I understand that we can select "Attach and Hold" for "After Create" Dropdown for each Correspondence rule and I can create multiple Correspondence rules with similar configuration. But, when we invoke the activity "CorrSend" which takes "BatchSend" as a parameter as "true", from where will it take the correspondence rules that I have created for processing in the Agent "SendCorr" with AQM? Thanks in advance.
