When you know what an email is about, but are not sure who sent it, try searching your mail by keyword. Save time scrolling by simply entering a word that you know is in the email and letting our smart search find it for you. For example, say that you are trying to find an email about a meeting. In the search box at the top of your mail, type in the word "meeting" and hit the 'Search mail' button. You'll see a list of results with all emails with that keyword mentioned.

Our dual purpose search allows you to search your mail or search the web in a single click. So if you're in the middle of composing a calendar invitation for a lunch meeting and want to search the web to find a cool spot nearby, just enter your query in the search box and select Search to open a new tab in your browser with your search results.

You can also drag and drop files from your computer into the Compose area and see them attach in no time.
