Everyone has a newsletter right now. If you subscribe a lot of them, they can also add to the clutter of your email inbox. There are lots of great newsletters. Ben Thompson's Stratchery, Morning Briefing from the New York Times, Axios AM and Politico Playbook are just a few that I like to read, but I often end up forgetting about them as I try to move through my inbox in the mornings. There's an app called Stoop, available for iPhone and Android, that makes discovering and reading newsletters a lot more enjoyable. You get a unique e-mail address that sends them right to the app, so you don't have dozens of newsletters collecting in your regular email inbox. Here's how to use Stoop.

Download Stoop and set up an account

First, download Stoop from the App Store on your iPhone or iPad, or the Google Play Store on your Android phone. You'll create an account that gives you a unique email address. Enter this email when you subscribe to newsletters, so that they get sent right to Stoop each time they're released. Make note of it because you'll need it in the next step.

Subscribe to some newsletters

Now you need to subscribe to some newsletters. This is a two-part process — subscribe and then confirm — but it's simple. First, tap the + button on the bottom of the app. You'll see curated lists, popular newsletters (including some of the ones I mentioned above), or you can browse by topic, like business, finance, lifestyle, news, politics, sports and more. There's a lot to pick from.

Some newsletters let you subscribe instantly, which means you don't need to enter in an email. It just connects right to the app. You'll see if this is supported through a small lightning symbol next to the newsletter. If you can't subscribe instantly, just enter in your custom Stoop email address. Then tap subscribe. You can also search for newsletters that aren't in the app. If nothing comes up during the initial search, choose "Search the web" and subscribe through the built-in web browser. This works for newsletters like those offered by CNBC.

After you've subscribed to a few, you may see a notification back on the home screen that asks you to confirm the subscription (if it wasn't one of the Instant subscriptions.) Tap this and confirm it to start receiving the newsletters.
