send email from my own and specific email address?

Hello @user335266 ,

In order to send from your own business / organization email address, you'd need to be self-authenticated. If you're unable to self-authenticate due to organizational restrictions, or because of using a free domain (gmail, yahoo, etc.) then you'd need to use the ccsend version we provide as part of authenticating through us. 

For more info, please see our Community's Email Authentication FAQ.
