Users can add a 'Contact person' to a customer account by clicking on the 'Contacts' button in the local menu under Customer/Customer. Here the user has the following options at the bottom of the contact person screen under 'E-mail recipient':
1) If the user enters a check mark in 'Contact person' under 'Email recipient' at the very bottom of the screen, then this person will ONLY receive mails for the orders where he or she has been selected on the order in the 'Contact person' field. This person now gets ALL emails to do with this order (so both confirmations and invoices).
2) If the user enters a check mark in any other field. e.g. in the 'Confirmation' field under 'E-mail recipient' then that person will receive ALL order confirmations for this customer whether or not they have been selected as the contact person on the order or not.
This means that if you have set the contact person up with a check mark in BOTH 'Contact person' and 'Confirmation' under 'E-mail recipient', then the person will receive mails for BOTH 1) and 2). So they will receive 1) ALL mails for the orders that they are selected on AND 2) ALL order confirmations for this customer even when they are not selected on the order as the contact person.
Uniconta does NOT offer a combination of 1) and 2) such that one can define that one contact ONLY receives, for example confirmations for the orders where they are selected as contact person. This is not currently an option.
