RawPixel/UdemyManaging your professional email may not be one of your official responsibilities, but having a handle on it will help make you more productive.

In a perfect world, you would only receive important messages at a manageable pace. In reality? We all have a few unread messages in our inbox from a few months ago.

Between relevant e-mails, calendar invites, and spam, organizing your inbox (let alone responding to those important messages) is easier said than done.

There are many articles that offer tips for cleaning out your inbox, but if you still haven't found a system that works, you should enroll in "Email Zero Inbox : The GTD Optimized Email Workflow."

Using David Allen's popular "Get Things Done" (or GTD) approach, instructor Paul Tilley will teach you how to clean out your inbox and make the most out of your workday. You'll learn everything from batching your emails, to sorting your inbox's labels, to lesser-known hacks that will increase your productivity. Though Tilley uses Gmail throughout this course, many of these tips can translate nicely to your Outlook, Yahoo, or Hotmail accounts.

If you're worried about spending more time learning about a new way to do things rather than actually being productive, don't be. The course is only an hour and a half long, so you can watch it during your lunch break your commute.

With a 4.3/5 rating on Udemy, many users love this course because it's straight-forward and packed with useful information. Several users praised it for actually helping them clean their inboxes.

"The biggest win for me in this course was creation of multiple inboxes," one reviewer said. "I have organized my personal email account and I look forward to tackling my work email tomorrow. The course gave me lots of new information about Gmail and I learned a few tricks even though I have been a Gmail user for over seven years."

If you're tired of watching your unread messages pile up, we have a feeling you'll like this course, too.
