If you have created any filter to prevent spam emails in your Yahoo Mail account, you will need to review the filter guidelines of Yahoo. You can find these guidelines below:

NOTES: if you are looking for some missing emails, make sure to check the Spam folder first because all emails go through the spam filter before going through other filters.

Empty Filters

If you have created an empty filter which doesn’t contain any rules, it will function according to the following:

  • Emails sent by an email address with an empty character will be routed to the Inbox.
  • If the empty filter is at the top of the filter list, rules of all the other filters will be voided and emails will be delivered to the Inbox.

Multiple Criteria

  • A filter will apply all of the rules you configure to identify which mail to filter.
  • It is best to create 2 filters if you wish to filter all emails that contain criteria 1 or criteria 2.

Conflicting rules

  • As filters are applied according to the order they are on the list, you will need to use the up and down arrows to make changes to the order.
  • There must not be a conflicting filter above a filter that is not functioning.
  • Make sure that you are not using negative criteria like “does not contain” with positive criteria like “begins with.”
