The more you know: switching to Gmail like a pro

Every day, tens of thousands of people switch from Microsoft Outlook® and other client-based software to Google Apps. To make the transition as smooth as possible, we thought we’d share some tips on using Gmail.

Embrace conversations (or not)

Conversations are a collection of messages with the same subject line and other similarities. When you click to read a conversation, you'll see all of the back-and-forth email responses that happen over the course of the entire email conversation.
If you prefer a more traditional view of your Inbox, you can always turn off Conversation view so that all emails arrive individually.

Forget delete, and archive your way to “Inbox Zero”

The average corporate inbox is only 300MB, which means too many people are forced to spend way too much time managing their inbox -- deciding which email to keep, and deleting the rest. With 25GB of storage, you probably won’t ever need to delete an email again because of storage limitations.

Search to sort

Gmail uses the power of search to help you quickly find what you want. Try it and you'll find some of the qualities that Google.com is known for: great accuracy and really fast search results. Search is particularly more effective than sorting when you’re looking through multiple gigabytes of email!

You may be accustomed to sorting email to find saved messages, which is a pretty limited way to find information because you usually know what you’re looking for.

[edit from Brian] Yes, search is very fast, but sometimes you still need to sort. 'Sort' has been a human tool for way longer than Google and email and Google seems to have ignored that.  However, like the new option to turn off Conversation view (Sept 29, 2010), sort is on the to-do list, so we will be able to utilize both search and sort soon.Labels instead of folders

Labels give you more flexibility than folders to organize your email. You can’t put an email into multiple folders, but you can apply multiple labels to the same message, which makes it easy to manage information that may fall into more than one category.

Work offline

These days you’re probably almost always connected to the Internet. But in those increasingly rare moments when you’re not, you can still access Gmail. When you’re offline, you can work in your browser to compose messages, search, organize mail, and do all of the things you're used to doing while accessing your email online.

With Premier Edition of Google Apps, you can continually synchronize with Outlook if you still prefer to use Outlook.

New features

As a web application, Gmail can be updated and improved without the trouble of purchasing, downloading and installing updates. This means Gmail will continually offer new functionality to help you be even more productive, like Priority Inbox, integrated voice and video chat, and labs such as Apps Search and Desktop Notifications.

We hope you enjoy the experience we offer -- we believe that ultimately, a fully-searchable, delete-nothing inbox makes for happy, productive people. But if you’re still not quite ready to use Gmail’s web interface, you can keep using Outlook or other clients of your choice.
