TM4C1294NCPDT: Is it a good idea to implement an attachment feature in TM4C1294NCPDT controller for SMTP protocol? Will assigning attachment take up memory of the controller?

Tool/software:

Is it possible to attach a '.csv' file to a mail sent through SMTP using TM4C1294NCPDT controller? How can the controller read the data from my system, lets say i have a '.csv' in my system to be sent via SMTP, is using the 256KB SRAM to stream the '.csv' file (read/write through chunks) a good approach? How am i supposed to implement this?
