Can not drag a Contacts card into a group mailing list

Hello epatch.

Thank you for using Apple Support Communities. It sounds like you're trying to add contacts to a group mailing list. If so, we'd like to help out.

You had mentioned that you're unable to drag them to the group mailing list. Is this a Smart Group? We would like to share a resource that can help you. Please check out the link below:

Create groups of contacts in Contacts on Mac

You'll want to review the section under "Create a group". You'll see ways you can add your contacts to groups if you can't drag them and additional details about Smart Groups.

We hope this information is useful. Cheers.
