Don't use Google Account Name to send email

I have a registered gmail account with name Harsh. While I want email to be sent with name as CAC. When I am sending mail using MxHero, mail is getting sent with Harsh as username. I want it to be sent as CAC. 

Gmail sends my mail with CAC as name while with MxHero it gets sent with Harsh. Please provide option to edit the name by which one wants to send the mail.
