I know the general etiquette is to send someone an invitation even if they said they probably can't come on the Save the Date. However, some people have already RSVPed no on our website or told us they can't come. I'd send them an invitation anyways but some of them didn't even fill in the address form on our save the date request so we'd have to call them each and ask for their addresses. Do I still call them and send them an invitation or is that pushy and annoying at this point.
