Emailing from Sage 300 to multiple email addresses

Hello,

I would like to know how to send emails from Sage 300 to multiple email addresses at the same time in Sage 300 ERP.

I see that under Customer there is a place to enter an email address and in the Contacts Tab, the same. Then in the Processing Tab for Delivery Method, it only gives the option of emailing to only one of those email locations. I have tried entering two addresses on the same line with a semicolon in between, but it gave me an error message.

Anything else I should try?
