Reading CSV Dynamic columns in SSIS

I want to create a path to Identify the columns in CSV.My task is to identify the CSV columns and if the CSV files has emails only, then its having a different data work flow to run and if the CSV having only Contact names ,then its  having a different workflow.So how should i start my Data work flow to Identify whether the CSV is having emails or Full names?

I want to try this without using Script Tasks.

Thanks you
