Almost a year ago, we launched Offline Gmail in Gmail Labs. By installing Offline Gmail, you’re able to use the normal Gmail interface to read and write mail, search, and organize, even when there’s no internet connection. And Flaky Connection mode speeds up Gmail when your connection is slow or unreliable.

Since we first launched in Labs, we’ve heard from a lot of you who tried Offline Gmail, and your feedback helped us make a lot of improvements. Aside from fixing bugs and making the whole offline experience smoother, we recently added two frequently requested features: an option to choose which messages get downloaded for offline use and the ability to send attachments while offline. Offline Gmail has proven particularly useful for business and schools making the switch to Google Apps from traditional desktop mail clients — they’re used to being able to access their mail whether or not they’re online, and Offline Gmail brings this functionality right to the browser.

Now, we’re happy to announce that Offline Gmail is graduating from Labs and becoming a regular part of Gmail. If you’re already using it, then you’re all set. While you’ll no longer see it on the Labs tab, you can tweak your settings and turn it on and off from the Offline tab under Settings. If you’d like to get started with Offline Gmail on your computer now, here’s how:

1. Click the “Settings” link in the top-right corner of Gmail.
2. Click the “Offline” tab.
3. Select “Enable Offline Mail for this computer.”
4. Click “Save Changes” and follow the directions from there.

Thanks for all of the feedback over the last year — and for putting up with the occasional bug or two. We’re going to have a little toast, and then get right back to working on more improvements for 2010.

P.S. We received some interesting pictures in response to our call for photos of people using Gmail offline in our last post. Our favorite so far came from Ugo, who is at a Saharawi refugee camp in south Algeria, where he uses Gmail offline most of the time and connects via a satellite phone to our servers just once a day.

In the early days of email, messages were simple text meant to be read on a terminal. But with the growth of the web came the advent of HTML email, and overnight people began expressing themselves through bold and italics, colors and images, and whatever else their creativity inspired.

If you like to use a specific text style for your messages, you’ve had to change the font every time you’re about to start typing out an email. Now, you can turn on default text styling from the Labs tab, then go to Settings and set your preferences just once.

Try it out and tell us what you think. If you live and breathe code, now you can set your default text style to a monospace font. If your life is purple, your email can be, too. But remember: whatever you see is what your recipients will see, so be nice to them and try not to clog the intertubes with ginormous bold italicized red script.

One of the most requested features for Offline Gmail has been the ability to include attachments in messages composed while offline. Starting today, attachments work just the way you would expect them to whether you are online or offline (with the exception that when you’re offline you won’t be able to include inline images). Just add the attachment and send your message.

If you have Offline Gmail enabled, you’ll notice that all your mail now goes through the outbox, regardless of whether you’re online or offline. This allows Gmail to capture all attachments, even if you suddenly get disconnected from network. If you’re online, your mail will quickly be sent along to its destination.

If you haven’t tried offline access yet, visit the Labs tab and follow these instructions to get started:

1. Select Enable next to Offline Gmail.
2. Click Save Changes.
3. After your browser reloads, you’ll see a new “Offline” link in the upper righthand corner of the Gmail page, next to your username. Click this link to start the offline set up process and download Gears if you don’t already have it.

Now that you can send attachments while offline, we’d love to see pictures of you using Gmail in unusual places while you’re disconnected from the web. Pictures of you using Gmail in an airplane, igloo, or submarine are all welcome. Email your photo to hikingfan@gmail.com and we’ll post the most interesting ones here.
