How do I eliminate the "on behalf of" on the email

[JoeP772]

I am one of the account emails that is on the profile. When i sent an email it always says <Joe@gmail.com > on behalf of <brian@gmail.com>. I am the one sending the email and do not want the email being sent on my behalf. 

How can i make it so it does not say this going forward?

Hello @JoeP772 ,

This wording is likely tied to your current authentication setup. I'd advise altering your current authentication, switching your account to self-authentication, or reaching out to our Delivery team for further guidance and insight on this element of your account.
