Edit the distribution list for lists and Smart Lists in Contacts on Mac
In the Contacts app on your Mac, choose Edit > Edit Distribution List.
Select a list or Smart List.
If you use multiple accounts in Contacts, the list is organised by account.
Click the rightmost column heading, then choose Email, Phone or Address.
The address or phone number currently used is highlighted in bold.
To use a different email, phone number or street address, select it, then click OK.
Contacts are shown in the distribution list only if they’re members of a list.
