How can I send email alerts to multiple recipiants?

Here is what I have tried,

Select SYSTEM, PREFERENCES, NOTIFICATION, EMAIL
and then I have tried several combinations to get the email to work
like
'[email protected]';'[email protected]'
"[email protected]";"[email protected]"

'[email protected]','[email protected]'

"[email protected]","[email protected]"

[email protected] ; [email protected]
[email protected] , [email protected]


I can send to both email addresses individually but not together

tks
