Email consolidating web application NutshellMail adds a reply feature to their Twitter-by-email messages—so you can update your Twitter status from anywhere you can access email. The new feature is simple—just click the Reply, Retweet, or Direct Message links under any of the Twitter replies, and your default mail client will open a new message to a specially formatted email address. Type in your message, and your Twitter status will be updated immediately—you can also update the status without replying by clicking Update underneath your current status in the email. We’ve mentioned this webapp before for its email consolidating features from Facebook or MySpace, but this new feature makes it worth a look if you want a quick way to update your status through email. If all these social media sites are giving you a headache, be sure to read our feature on getting productive with social media (and staying sane)—or you could take it the other direction and add Twitter results to Google search.
