You can add additional emails per contact, the main reason for this is that some people have a work and personal email address. Although we have to admit, in our experience the majority of people don’t mind wasting their company’s time unless they work for Big Brother or something.
To add additional contacts per email:
1. Open up Address Book.
2. Select contact –> wheel-click and select ‘Edit’.
3. In the contact information screen –> wheel-click and select ‘Add Email Address’.
4. Enter second email –> wheel-click and select ‘Save’
