Email a group or Smart Group in Contacts on Mac
You can create a new email message addressed to a group or Smart Group, right from Contacts.
In the Contacts app on your Mac, do any of the following:
Control-click a group or Smart Group in the sidebar, then choose Send Email.
A new email opens in the Mail app, addressed to the group or Smart Group.
Drag a group or Smart Group from the sidebar to an address field in an email you’re writing.
In your email, either the group name or individual contact names are shown, depending on how Composing preferences are set in Mail.
If the group name is shown but you want to see the individual contact names instead, click the arrow next to the group name, then choose Expand Group.
Tip: When you’re addressing an email, you can see all the available addresses for a contact by clicking the arrow next to their name. To email the contact using more than one of their addresses, copy and paste their name, click the arrow, then choose another address.
If any group members have multiple email addresses, you can edit the group distribution list to select which address to use whenever you email the group.
