Send email with dynamic recipients & contents on Job completion

Hello,

  Here is the scenario - The DS job is writing data from a SQL table containing task lists to a csv file on a daily basis. Every day new tasks are added to the data. Upon job completion, DS needs to send out an email notification dynamically to all the assignees with the notification of the new tasks assigned to them. For ex. 3 new tasks are assigned to A and 2 to B, then on completion of the job each should get an email notification with the task numbers assigned to them - in this case 3 new nos. to A and 2 new nos. to B.

Please guide me towards the best way to accomplish this via DS
