We indeed recommend that each author link their account with their own WordPress.com account, thus creating their own Post By Email address.
You could of course share your own Post By Email address with each one of your authors, but it would cause 2 issues:
- When one of the authors uses the email address to publish something, it would get published under your name
- You would lose control over that email address. If you wanted to revoke publishing access to one of the authors, you’d have to reset your own Post By Email address, thus disabling access to all other authors as well until you send them the new email address.
I would consequently recommend that you ask your authors to link their account with their own WordPress.com account by going to the Jetpack menu in their dashboard.
It won’t affect your own account, and the main Jetpack connection on the site, unless you break that connection yourself by disconnecting from WordPress.com in the Jetpack menu while being connected with the account you used to activate Jetpack.
Connecting the non-admin account to the sites account broke my stats.
Could you post your site URL here, so I can have a look?
