Twitter and Facebook and news alerts all prove it: The best form of one-to-many communication is the email newsletter. The Lifehacker staff follows newsletters for morning briefings, unique takes on tech, or personal stories. These are our favourites.

Everyone who works in a creative field, or wants to, should subscribe to the monthly newsletter Three Cents. In each issue, writer and editor Manjula Martin writes three brief essays and lists some well-curated links about creative work. It's helpful for learning industry norms and expectations, and it's a great way for freelancers and work-from-home creatives to feel less isolated.

If you're a RSS user who hates getting newsletters in your email, Kill the Newsletter is a simple little service that will kick those newsletters over to an RSS feed, so you can peruse them at your leisure.
