Google stores the emails and, where available, the names of all people you exchange emails with. These are stored in the "Other" contacts group.
Covve does not import these by default as they tend to include hundreds (if not thousands) of plain emails and contacts have just emailed us once (e.g. I wouldn't want email@example.com to be in my address book).
Nevertheless, to import these contacts into Covve:
- Sign-in to Gmail
- Click on ‘contacts’
- On the left panel click on ‘other contacts’
- Select the ones you want to bring into your address book
- Click ‘add to my contacts’ on the menu above the contact list
