some sample date input / expected out would be helpful. In general, we would group the data and return a list of data tables
TableList | List(Of DataTable) =
(From d in dtData.AsEnumerable
Group d by d(“Email”).toString.Trim into grp=Group
Select t = grp.CopyToDataTable).toList
TableList | List(Of DataTable) =
(From d in dtData.AsEnumerable
Group d by d(“email”).toString.Trim into grp=Group
Select t = grp.CopyToDataTable).toList
then iterate over the table list - for each activity | TypeArgument: DataTable and:
prepare the email - for datatable to HTML Table we can use activities from the marketplace or the Create HTML Content Activity
