Secondary email account
My main email account is a gmail one in my name, but my wife uses my computer and I have set up a gmail mail account in her name and with her individual email address. Yet when she sends an email from her account, the 'From…' address shown at its. head is mine, not hers. (If I change it in Mail Preferences, it changes the 'From…' address in my personal emails also.)
Is there anything I can do to make my wife's emails show her email address as the sender's address while keeping my email address as the sender's address in my emails?
Thank you in anticipation of help.
