Our spam detection feature uses a set of algorithms to determine which of your incoming faxes are spam and which are not. Our system also spams any messages that come from sources known to send out spams on a routine basis.
Incoming spams are not blocked but rather flagged as spam and placed in the spam folder in your archive. You will not be notified nor charged for faxes flagged as spam, and can review the faxes at any time by going to your spam folder.
Aside from our spam blocking feature, you may block any specific fax number to not receive any document from that source. To do so, you can use our blacklist feature.
