Well you have to wonder if the address was removed from company-wide email lists(if it was ever registered).... would be odd to get an email invitation to you own memorial service, though it did happen to my former co-worker after he was killed. Boss sent an email to everyone at the office(used CC instead of BCC or an email list...) so the guy essentially received an invitation to his own funeral. I guess it's always safe to assume that the person who died will be at the funeral.
