Gmail – How to enroll in Gmail

I have tried sending from Gmail using another account (not facebook) and it worked.

These are the steps to follow :

1. Sign to you Gmail account
2. Click the Gear button and choose Settings
3. Go to the "Accounts and Import" section
4. Under "Send mail as:", click on "Add another email address you own"
5. A new browser windows will open - follow the instructions to add the Facebook account.
6. Gmail will send you a verification email with a code to the Facebook address.
7. Copy the code to the verification window, or click on the link.
8. From now on, when you Compose an email in Gmail, the "From" will have a drop-down list that allows choosing the other account. The Gmail account stays the default.

As I said, whether this procedure works with Facebook is still to be verified, but as far as I know this is the only procedure that achieves this purpose in Gmail.

Until Google figures a way to have Gmail read your brain waves, it cannot reliably tell if you've read the message. Some mail clients mark a message as "read" only after it has been displayed a certain number of seconds, which might be closer to what you want. But that's not available in Gmail.

That's not to say that there aren't workarounds.

You could enable the Message Sneak Peek lab feature: Click the gear icon -> Settings -> Labs, scroll down to Message Sneak Peek, and click Enable. Go back to your inbox and right-click on any message. The message will be displayed in a popup window, without being marked as read.

Another thing I find myself doing, is mark a message unread after I've opened it, by clicking More -> Mark as unread (or press Shift+U if you have keyboard shortcuts enabled).

Also, starring messages is perhaps the most obvious way of keeping track of important emails that I need to deal with later. I use this in combination with the Multiple inboxes lab feature, so that a section of my inbox view is reserved for starred messages. When I've dealt with the message, I unstar it, and it is archived.
