After hearing consistent feedback that you wanted more control over your contacts, we've changed the way Gmail suggests contacts to you. Up to this point, if you emailed someone five times, we'd automatically move them into My Contacts. Now, we'll no longer automatically add contacts to your My Contacts group. Instead, you can go to Suggested Contacts, select the contacts you'd like and move them into My Contacts. All of your contacts -- whether they're in My Contacts or Suggested Contacts -- will continue to show in auto-complete as you're composing messages.
As part of this change, we're moving previously auto-added contacts back into Suggested Contacts. Only contacts that you've edited, imported or added to a group will remain in My Contacts. This will provide everyone with a clean slate and, we hope, a better point for syncing contacts with mobile devices (for example with Android). We'll be rolling this change out to everyone over the next few days.
We realize there's a lot we can do to make Gmail contacts even more useful, and the feedback we received last time we updated the contact manager was helpful, so keep letting us know what you think.
