Advanced options

If you click "Show advanced options", there are some extra options;

  • Email account - you can specify which of your email accounts you'd like this filter to apply to
  • Recipient email - if you have multiple aliases and only want to block a sender from emailing one of them then you can set that here
  • Sender email - when creating a filter you can set specific sender addresses that you want the filter to apply to, on top of the rest of the filter options.
