Great question! Your inventory emails are managed in your Square Dashboard, you can edit the email address that you receive those emails right from your Square Dashboard (you can also toggle on or off your email notifications). 
Another thing to keep in mind is that any employees that are labeled as "administrator" will receive those email notifications along with any employees labeled "owner". As these two permissions are given full access to your Dashboard and notifications so your employees with those two permissions will always receive those emails.
