How can i change what displays in my sender's name?

When I was registering my Zoho account, I used my real name. Though I put my business name where necessary at the end of the day. But whenever I send a mail with it displays my real name as the sender's name. I have removed my real name from everywhere I can find it but it still shows my name as the sender's name. How can I really get it to stop showing my name?
