Due to the display of the organizer and their email address in the information block of the event, only one email address per organizer is recommended. You may try adding a second organizer with the same name and the second email address to get the notifications going both places. This will mean, however, that your organizer will display on the event twice, one with each email address.

Thanks for your quick reply. Unfortunately this is not very practical, I will ask the plugin developer if he can do something for this

Good luck. They have been less than helpful over the years.
