Does Geary come with any contact management? I'd like to create and maintain mailing lists and contacts. Does this feature exist somewhere in Geary?
Geary does not have a contact management interface, but it does store contacts for auto-completion. These contacts are pulled from the emails that it has downloaded.
There are long-term goals for Geary to integrate into a system-wide contacts database (so a separate Contacts app could be used), but this is not yet implemented.
