How do you connect Gmail contacts to easily tag co-makers?
Connect Gmail contacts to tag as co-makers
In the Co-Makers section of your profile, search for and add a co-maker. When prompted to enter their email address, select the Link and Search your Gmail Contacts button.
You will be prompted to connect a Gmail account that you own. Once connected, begin typing your co-maker’s email address in the email entry form. This, and all future email addresses, will auto-complete if your co-maker is in your contacts.
