Hi Yashank,
I do not know if the table you are storing the data has a target mapping created .
You can simply query the table where the responses are stored and send the delivery. if the table has a field like email and there is no target mapping created , you can create a custom target mapping to target that field of the table.
Target mapping
Else you can also change the dimension using the "Change dimension" activity in a workflow to change the targeting dimension to recipient from your table by reconciling the email field .
