Fix Gmail Spam Filter

There are a few reasons why your Gmail spam filter might not be working. Below are some unique reasons and their respective solutions.:

  • You have accidentally marked a spam email as “Not Spam”: This will train the spam filter to think that the email is not spam, and it will be more likely to let future emails from that sender through. To fix this, go to your spam folder and mark the emails that you know are spam as “Spam”.
  • Your spam filter is set to a low sensitivity: This means that the spam filter is less likely to mark emails as spam. To fix this, go to your Gmail settings and change the spam filter sensitivity to a higher setting.
  • You have created a filter that is blocking spam emails: If you have created a filter that is blocking spam emails, it will need to be edited or deleted. To check your filters, go to your Gmail settings and click on the “Filters” tab.
  • Your spam filter is not update:  Google is constantly updating its spam filter, so it’s important to make sure that yours is up to date. To check for updates, go to your Gmail settings and click on the “Help” tab.

  • The filter is not enabled: Make sure that the filter is enabled. You can check this by going to your Gmail settings and clicking on the “Filters” tab.
  • The filter is overlapping with another filter: If you have two filters that are trying to apply the same action to the same email, only one of the filters will work. Try editing or deleting one of the filters to see if that fixes the problem.
