In Gmail, how do I create a contact from a recipient of an email? For sender, there is 'Add to Contact List' but there doesn't appear to be anything similar for the To: or Cc: fields.
Is there an easier way than creating the contacts manually?
This is a little bit of a pain, and I'm not 100% sure about it, but it seems to work in my tests.
If you click the name of the person you want to add as a contact while viewing the message, there is an option to click their e-mail address to send them a message. Click that, then discard the message. Click their name again in the original; there is an option under "More" for "contact details". Click that and you can add the other stuff you want and add them to a real group.
It appears that sending--or at least, starting to send--a message to an e-mail address puts it into your contacts under "All Contacts".
Google has added several improvements to Gmail since I originally posted this. drnbv's answer is much more useful.
I had the same problem except I had the list of about 15 contacts that I wanted to add as contacts and add as a group. I did not want to have hover over each name and individually add them and then add them all to a contact list after. I found a quick solution, here is what I did:
Beside the list of recipients I pressed the 'show details' down arrow. Then I copied the list of recipient emails.
I went to the contacts view for Gmail. Clicked Add to Contacts and pasted the emails in.
At the left hand side I expanded the list of contact groups and clicked "New Group...". I followed the steps to make a new group. Then I clicked the "Add to contact list" button and pasted in the list of contacts again.
