Why Is My Gmail Spam Filter Not Working? How To Fix

Is your Gmail spam filter not working the way you’d like? Learn how to change Gmail spam settings and discover all the ways Clean Email’s Screener feature can help prevent spam from getting into your mailbox.

Why Is My Gmail Spam Filter Not Working?

One of the benefits of using Google’s mailbox is the fact that it supposedly filters spam automatically. Unfortunately, the spam email blocker for Gmail isn’t always as intuitive as we would like for it to be, and sometimes it stops working entirely. But why?

The most common issue is that you accidentally clicked “not spam” on a message that was, in fact, spam. This can easily be remedied by selecting the junk messages and flagging them as such (which we explain how to do in more detail below).

Sometimes, the filters you set up can inhibit the spam filter from working correctly. You can check this by going to Settings → See All Settings → Filters and Blocked Addresses. From there, you can edit your filters or delete filters that may get in the way of spam recognition.

If you gave out your email for something online or in-person, you might have essentially signed up for spam by giving out your email address. When you give out your email, there are usually checkboxes to consent or remove consent for vendor promotional messages. This can be frustrating, but as you know, it’s something you can fix.

Also, if you received a junk message and clicked on one of the links in that message, you could have actually sent yourself more junk this way. This creates a much more complicated issue, but there are ways to fix it both within Gmail and the Clean Email app, which we will share more about later on.

How To Fix Gmail Not Filtering Spam

Now that you know why your junk filter may not be working properly, it’s time to learn how to set spam filter in Gmail so that it starts doing its job once again.

If you notice your Google spam filter not working, you may need to perform one (or more) of the following suggestions to reset your Gmail spam filter settings.

1. Flag Messages as Spam

Sometimes you may notice Gmail not filtering spam messages even though they seem like obvious phishing or malware messages. If that’s the case, you can mark as spam in Gmail manually to help train the filter.

To flag messages as spam in Gmail, simply:

  1. Open your Gmail inbox.
  2. Select any message that you want to flag.
  3. Choose Report as Spam (the stop sign with an exclamation point) from the options in the top menu.

2. Set Up a Spam Filter Rule

If you can’t handle your Gmail spam filter not working even after flagging some messages in your inbox, you can create Gmail rules that serve as junk filters. These rules will automatically place messages in your Spam folder based on the criteria you specify.

To set up a spam filter rule:

  1. Log in to your mail account on the web.
  2. Navigate to the search bar, then click Show Search Options to the right of the box.
  3. Specify the search criteria for the message and click Create Filter.

  6. Click the Create filter button again.

3. Check if Filters are Overridden

Although the Gmail spam filter works fairly well, you can override it within the settings. Whether you did this on purpose or by mistake, chances are a few clicks will fix the issue and your Gmail spam filter settings will return to normal.

Here’s how to check and fix this issue:

  1. Login to your Gmail account.
  2. Click on Settings → See All Settings.
  3. See all settings in Gmail
  4. Select the Inbox tab.
  5. Scroll down to Filtered Mail.
  6. If Override Filters is selected, choose Don’t Override Filters instead.

Prevent Spam Entirely With Clean Email

Sometimes, the spam blocker for Gmail isn’t enough to meet the needs of your situation. If that’s the case, you may need an inbox management app like Clean Email instead.

Clean Email lets you do many things to stop getting unwanted emails, including screen out messages from unknown senders through a tool called Screener. When enabled, this feature sends all emails from unrecognized senders into a dedicated quarantine folder so you can review them before placing them in your inbox.

Then, when you access the Screener tab, you can decide whether to block or allow these emails into your main inbox.

Additionally, you can use Screener with other tools, like Auto Clean, to set up additional rules and inbox automations. The Auto Clean feature is much more intuitive and customizable than Gmail’s filters. Auto Clean uses “if-then” triggering, and gives you options to perform tasks like auto-delete, archive, mark as read/unread, star/unstar, move to folder, and more. Besides, you can pause the rules anytime without the need to delete them and create new ones from scratch if you plan to resume these rules in the future.
