Matelot,

1. Open Contacts
2. Click View > Current View > By Category
3. Click the Category to highlight it (the contact for that category should be listed below)
4. Click Actions > Create > New Message to Contact

This should open a new email message with every contact's email address in the To: address line.

Hope this helps you accomplish what you're doing!
