New in Gmail Labs: Smart Labels

People get a lot of email these days. On top of personal messages, there are group mailing lists, social network notifications, credit card statements, newsletters you might have signed up for, and promotional email from a shopping site you used once months ago. Gmail’s filters and labels were invented to help manage the deluge, but while I have about 100 filters that triage and label my incoming mail, most of my friends and family have all their messages in a giant unfiltered inbox.

Last year, we launched Priority Inbox to automatically sort incoming email and help you focus on the messages that matter most. Today, we're launching a complementary feature in Gmail Labs called Smart Labels, which helps you classify and organize your email. Once you turn it on from the Labs tab in Settings, Smart Labels automatically categorizes incoming Bulk, Notification and Forum messages, and labels them as such. “Bulk” mail includes any kind of mass mailing (such as newsletters and promotional email) and gets filtered out of your inbox by default (where you can easily read it later), “Notifications” are messages sent to you directly (like account statements and receipts), and email from group mailing lists gets labeled as “Forums.”


If you already use filters and labels to organize your mail, you may find that you can replace your existing filters with Smart Labels. If you're picky like me and still want to hold on to your current organization system, Smart Labels play nice with other labels and filters too. On the Filters tab under Settings, you'll find that these filters can be edited just like any others. From there, you can also edit your existing filters to avoid having them Smart Labeled or change whether mail in a Smart Label skips your inbox (which you can also do by just clicking on the label, then selecting or unselecting the checkbox in the top right corner).

Labs in Gmail are a great testing ground for experimental features, and we hope Smart Labels help you more effortlessly get through your inbox. If you notice a message that was automatically labeled incorrectly and want to help us troubleshoot, you can report miscategorizations from the drop down menu on each message (in doing so, you’ll donate the full message to our engineers so that we can improve the feature). Give it a try and send us feedback on how we can make it work better for you!

Gmail back soon for everyone

Imagine the sinking feeling of logging in to your Gmail account and finding it empty. That’s what happened to 0.02% of Gmail users yesterday, and we’re very sorry. The good news is that email was never lost and we’ve restored access for many of those affected. Though it may take longer than we originally expected, we're making good progress and things should be back to normal for everyone soon.

I know what some of you are thinking: how could this happen if we have multiple copies of your data, in multiple data centers? Well, in some rare instances software bugs can affect several copies of the data. That’s what happened here. Some copies of mail were deleted, and we’ve been hard at work over the last 30 hours getting it back for the people affected by this issue.

To protect your information from these unusual bugs, we also back it up to tape. Since the tapes are offline, they’re protected from such software bugs. But restoring data from them also takes longer than transferring your requests to another data center, which is why it’s taken us hours to get the email back instead of milliseconds.

So what caused this problem? We released a storage software update that introduced the unexpected bug, which caused 0.02% of Gmail users to temporarily lose access to their email. When we discovered the problem, we immediately stopped the deployment of the new software and reverted to the old version.

As always, we’ll post a detailed incident report outlining what happened to the Apps Status Dashboard, as well as the corrective actions we’re taking to help prevent it from occurring again. If you were affected by this issue, it’s important to note that email sent to you between 6:00 PM PST on February 27 and 2:00 PM PST on February 28 was likely not delivered to your mailbox, and the senders would have received a notification that their messages weren’t delivered.

Thanks for bearing with us as we fix this, and sorry again for the scare.
