Change default name

Change default name

Hi, dudes. I have a question, when I send a mail to someone else, it always appears a name next to my email adress, how can I change that?

Ex:

From: danielcastillodelrazo < daniel@diarioproyecto.com>
To: Laura Cuéllar < lauracdr@hotmail.com>

I tried and tried changing things in Zoho, but I don't want my full name to appear on all emails I write, th anks for any kind of help :)
