But I cannot get the group list of contacts to enter automatically into "to" on the iPad as happens automatically on the desktop iMac. So the "groups" on the iPad really doesn't have any functionality other than giving one a list of who is in a group per my assignment on my iMac.
So I end up entering manually each individual in a group in the "to" line when I want to send an email to a group from my iPad. On the iMac, selecting a contacts group will automatically list the addresses of the people I have put into a group. A known problem, and any solution?
