Why am I getting so much Junk mail in Outlook?

Last Updated on May 27, 2023 by Amit Bansal

In today’s digital age, most of us are familiar with junk mail in our email inboxes.

With Outlook being one of the leading email service providers, it’s not surprising that a significant number of users face the issue of receiving excessive junk or spam emails.

There are many reasons why we might be getting so much junk mail in our Outlook accounts, and understanding the factors contributing to this problem is crucial in finding ways to prevent or reduce it.

One of the primary reasons for an increase in junk mail is that our email addresses have probably become public.

Listing email addresses on websites or using the same email for multiple online sign-ups makes it easier for spammers to target us.

Additionally, the way we interact with emails can also impact the junk mail we receive.

Marking spam emails as junk helps train the email provider’s spam filter, which then improves its efficiency in detecting and filtering out similar emails in the future.

Furthermore, the default settings in Outlook’s Junk Email Filter might not always be adequate to keep all unwanted emails at bay.

Modifying the Junk Email Filter level or using additional features, like the Sweep function, can help in managing and reducing the amount of junk mail we receive on a regular basis.

This article is all about how to automatically delete junk mail in Outlook.

What are junk mails?

Unnecessary email on your mailbox directly received from such marketing platforms for which you have not even subscribed, related to some kind of product or service. An unsolicited email is called spam mail.

Does junk email automatically delete, yes, Outlook helps the user to get rid of junk mail in two separate ways.

Understanding Junk Mail in Outlook

Definition and Types

Junk mail, also known as spam, is an unwanted and unsolicited email that finds its way into your Outlook inbox.

There are several types of junk mail, including spam emails, phishing attempts, and emails from mailing lists you didn’t sign up for.

Outlook has a built-in junk email filter to help manage and reduce the volume of these messages, but occasionally some legitimate messages might be misidentified as spam.

Common Sources

There are various sources of junk mail, and understanding them can help us reduce the number of unwanted messages in our inboxes. Some of these sources include:

  • Mailing lists: When signing up for online services or purchasing products, we may unknowingly get added to mailing lists that send promotional emails or newsletters. We can reduce our exposure by using a separate email address for subscriptions or reviewing the privacy policies of websites before signing up.
  • Data breaches: If our email addresses are exposed in data breaches, spammers might use them to send junk mail. Staying vigilant about data breach news and regularly changing our passwords can help minimize the risks associated with this source.
  • Publicly listed email addresses: If our email addresses are publicly listed on websites or online forums, spammers might use automated tools to collect them and send junk mail. Removing our email addresses from public sites or using email obfuscation techniques can minimize this risk.
  • Phishing attempts: These are emails that try to trick us into giving out personal information, such as login credentials or financial information. They often look like they come from legitimate sources but are actually crafted by criminals. Outlook’s spam filtering tips can help in protecting our inboxes from such dangerous messages.

By being cautious about how and where we share our email addresses, we can reduce the amount of junk mail we receive.

Additionally, adjusting the settings of Outlook’s junk email filter can help further minimize spam messages and keep our inboxes more manageable.

Outlook’s Junk Mail Filtering System

Outlook offers several features to help manage the amount of junk mail you receive.

In this section, we will discuss the default settings, spam filter features, and options for blocking and creating safe sender lists.

Default Junk E-mail Filter Settings

By default, Outlook is set to filter junk mail automatically. To change these settings, you can navigate to the Junk E-mail Options under the Home tab in Microsoft 365.

Here, you have the choice to select from the following options:

  • No Automatic Filtering: This option turns off automatic junk email filtering, but you can still manually filter messages.
  • Low: Filters obvious junk mail.
  • High: Filters most junk mail, but may flag some legitimate messages as junk.

Spam Filter Features

Outlook’s junk mail filtering system includes several spam filter features.

One useful feature is the ability to report spam by selecting the Report Spam option, which helps improve the overall spam filtering process.

Additionally, the junk mail filter in Outlook analyzes incoming messages and sends those identified as spam to the Junk E-mail folder.

Block Senders and Safe Lists

To further control your inbox, Outlook provides options for creating a Blocked Senders List and Safe Senders and Safe Recipients Lists.

Here’s how they work:

  • Blocked Senders List: You can add email addresses and domains to your Blocked Senders List to prevent their messages from reaching your inbox. To do this, go to the Blocked Senders tab in the Junk E-mail Options window.
  • Safe Lists: When using the Safe Lists Only filter option, you’ll only receive messages from those on your Safe Senders or Safe Recipients Lists. Emails from senders not on these lists will be sent to your Junk folder. To manage your Safe Senders and Safe Recipients Lists, visit the Junk E-mail Options in Outlook.

By utilizing these features and settings, we can better manage the amount of junk mail we receive in our Outlook inbox and ensure a more pleasant emailing experience.

Managing Junk Mail in Outlook

Review and Unsubscribe Options

We often receive unwanted emails in our Outlook inbox due to various reasons such as promotional offers, subscriptions, or data breaches.

One effective method to declutter junk emails is to review the emails and unsubscribe from any unwanted mailing lists or promotional content.

Most of these emails contain an “unsubscribe” link at the bottom. This process not only helps in reducing the number of junk emails but also increases the efficiency of our inboxes.

Customizing Filter Settings

Outlook provides various filtering options that we can use to manage our junk email. To access these settings, click on the Home tab, go to the Delete group, and then click on “Junk” followed by “Junk E-mail Options“.

Here, we can choose the level of protection we need. From options like “No Automatic Filtering” to “Safe lists only“, we can customize our junk email preferences according to our needs.

Moreover, we can also add specific email addresses to the “Blocked Senders” list, which will prevent emails from those addresses from reaching our inboxes.

For Mac users, click the Tools menu and select “Junk Email Preferences” to access similar options.

Using Third-Party Tools

Apart from utilizing built-in Outlook features, we can also use third-party tools to help manage and reduce the amount of junk email in our inboxes.

These tools add an extra layer of protection, often using advanced algorithms and machine learning to identify and filter out malicious or scam emails.

Some of these tools offer additional features like temporary disposable email addresses, preventing unwanted emails from ever reaching our primary inbox.

In conclusion, we can effectively manage junk mail in Outlook by reviewing and unsubscribing from unwanted content, customizing our filter settings, and using third-party tools, improving our overall email experience and inbox organization.

Outlook Mobile App and Email Clients Integration

When using Outlook mobile app on our Android or iOS devices, we may frequently encounter junk mail or spam.

To manage this effectively, let’s explore a couple of sub-sections related to spam management in the Outlook mobile app and syncing settings with Gmail and Google Workspace.

Outlook for Android and iOS Spam Management

In the Outlook mobile app, we can manage email spam through its built-in spam filtering and by marking emails as spam.

To manually mark an email as spam, follow these steps:

  1. Open the Outlook mobile app.
  2. Select the email you’d like to move to the spam folder.
  3. Click the ‘Move to’ icon at the bottom toolbar.
  4. Select Junk.

This process helps Outlook to learn and improve its spam filtering over time, ensuring that legitimate emails are not misdirected to the spam folder.

We should also regularly check the Outlook spam folder to ensure that no valuable emails have been mistakenly flagged as spam.

Additionally, we can safeguard our devices from malware and other security threats by keeping the Outlook app updated and configuring the mailbox settings according to best practices.

Syncing Settings with Gmail and Google Workspace

If we use Gmail or Google Workspace with our Outlook mobile app, syncing the settings between these email clients can help to improve spam management. Here’s how to set it up:

  1. Open the Outlook mobile app and navigate to the mailbox settings.
  2. In the Add Account section, select Gmail or Google Workspace.
  3. Input your Gmail or Google Workspace email address and password.

Once the accounts are linked, Outlook will sync the spam filtering settings configured in Gmail or Google Workspace.

This ensures consistent behavior across both email clients and helps to minimize the amount of spam reaching our inboxes.

  • Reviewing message sources: When we receive suspicious emails, we should verify the authenticity of the sender by checking the message source. This can help us identify phishing attempts and prevent compromising our device security.
  • Securing our device: Keeping our Windows device updated with the latest security patches and running antivirus software will help protect us against malware that might enter our system through junk mail. Regularly scanning our devices for threats is another essential practice.
