How to Stop Junk Email in Outlook

If you’re an Outlook user, this article is for you because it explains how to stop junk email in Outlook. Don’t worry: stopping junk email is not difficult, especially not with Clean Email, a bulk email organizer that uses powerful filters and clever automation to make junk email a think of the past.

7 Tips on How to Stop Junk Email in Outlook

By the end of 2019, the number of worldwide email users increased to over 2.9 billion, and the number of junk messages will only grow with time. Unless you learn how to stop receiving junk email, you can expect your inbox to eventually be so full of useless messages that using it will be nearly impossible.

The good news is that learning how to get rid of junk email doesn’t require much effort, and it certainly doesn’t require any expert knowledge. All you have to do is familiarize yourself with seven simple email management tips and use Clean Email as an alternative to the Outlook spam filter.

1. Don’t Respond to Spam

Never respond to spam messages. Ever. It may seem obvious, but you would be surprised how many people break this simple rule and open unsolicited emails. Sometimes, they even download attachments, which is how most malware infections begin.

The trick is to learn how to separate legitimate messages from illegitimate ones. If you don’t recognize the sender address, you’re most likely dealing with an unsolicited email from a clever spammer who has managed to circumvent the Outlook spam filter. Look at the subject line and think hard if it makes sense and doesn’t contain grammar mistakes.

Spammers often make outrageous claims and write emails that are full of spelling errors and grammar mistakes. Legitimate senders, on the other hand, take time to proofread their emails to make a good first impression. It’s also very rare for legitimate senders to send emails with attachments without first touching base.

2. Don’t Share Your Email Address

Do you know how spammers get your email address in the first place? They usually find it posted online! We understand that it can be tricky, especially if you have a website or maintain an active online presence but try not to publish your email address online. If you absolutely must share it with others, at least disguise it by substituting the @ symbol with the word “at.” This won’t fool all email address scrapers used by spammers, but it will throw off a good percentage of them.

When you do give your email address to someone else, pay attention to your inbox and monitor the number of spam emails you receive. A major uptick in the frequency of spam emails could mean that the person with whom you’ve shared your address has published it somewhere. When registering on websites, consider using a disposable email address instead of your real one. There are many services that let you create as many disposable email addresses as you want, and most of them are free.

3. Report Junk Emails

The sad truth is that the Outlook junk email filter leaves a lot to be desired. You can, however, train it by reporting junk emails. When you mark a message as spam, it will not only disappear from your inbox but also appear on Outlook’s junk email filter. Next time the same sender attempts to send you a similar junk message, there’s a very high chance that the email will be detected and stopped from ever reaching your inbox (learn more about how to stop spam emails and how to block emails on Outlook).

4. Unsubscribe from Promotional Emails

Promotional emails are the curse of our modern era. It’s hard to avoid them because there are still many websites and services that require you to explicitly opt out from receiving them, and some simply don’t care. The frequency of promotional emails can be so high that it doesn’t take a long time to reach storage limits in Outlook, despite the fact that Microsoft offers 15 GB of email storage space per free account and 50 GB of space for Office 365 Home and Office 365 Personal subscribers.

In the United States, the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 (CAN-SPAM Act of 2003), mandates that a visible and operable unsubscribe mechanism is present in all emails and specifies that consumer opt-out requests are honored within 10 business days. European GDPR takes things to the next level, requiring clear proof of opt-in from email recipients. As a result of these and other laws, most promotional emails today contain an unsubscribe link somewhere at the bottom of the message. All you have to do to unsubscribe is click on it.

5. Get a New Email Address

Getting a new address just to stop junk email may seem like a drastic option, but we recommend it to everyone who’s losing the fight with spammers. Outlook lets you create as many new addresses as you need for free, and you might even be able to snatch a good username if you don’t wait too long. At the very least we recommend you create another email address just for online registrations and various other activities that might lead to junk infiltrating your inbox.

6. Use Temporary Email Services

If you’re not keen on managing another inbox just to stop junk emails from infiltrating your Outlook account, you have another option: a temporary email address.

A temporary account looks and works just like a regular email address except that it’s not meant to be used long-term. Most temporary addresses expire after anywhere from 10 minutes to a couple of hours, so using them for regular communication is not advisable.

Instead, we recommend you use a temporary email address as a way how to stop receiving junk email from various websites that force you to create a user account. Here are a few reputable providers of temporary email services that you can choose from:

Besides temporary email services, you should also learn how to stop receiving junk email in Outlook with burner emails extension like Burner Mail for Chrome. Browser extensions are convenient to use because they are always just one click away, and they offer various useful extra features, such as real-time email notifications.

7. Configure Your Outlook Junk Email Filter on PC or Mac

If you're using Microsoft Outlook on your PC or Mac, you should tweak Outlook junk mail settings to improve the performance of the Outlook spam filter.

To do this:

  1. Open Microsoft Outlook and click the Home tab, click the Junk icon (a person with a prohibited sign), and select the Junk E-mail Options button.
  1. In the Options tab, look for junk email protection settings and pick one of the available options:
  1. Save your choice.

That's how to stop junk email in Outlook on PC or Mac. To create the best spam filter for Outlook possible, we highly recommend you manually add addresses and domain names that you always want to be treated as junk email on your Blocked Senders List. You can do this in the Blocked Senders tab of the Junk E-mail Options or Junk Email Preferences window.

Bonus: Clean Email

One of the most effective ways how to stop getting junk email involves Clean Email and its “Auto Clean” and “Unsubscriber” features. Clean Email is a bulk email organizer that can analyze your inbox without reading your emails and separate junk emails from legitimate emails. It allows you to unsubscribe from newsletters and unwanted subscriptions with the click of a button, and it’s just as easy to delete or archive hundreds or even thousands of junk messages.
