old email attached to this email address at zoho

Hi.
When people see my email they see it coming from mightym0729 which is my yahoo email. I set this email up with you at Zoho to have a separate email that I can receive emails and send emails from pattyshealthbeauty@zoho.com I did go and put pattyshealthbeauty@zoho.com as the primary email but for some reason the mightym0729 keeps showing up and confuses people who get my emails. Maybe I did something wrong..but I just want this account to show pattyshealthbeauty@zoho.com only!!!! Otherwise really like this email ...no clutter...I plan on doing some other things with Zoho
Thanks
Patty
