What Is The ZapBL Blacklist?

ZapBL Blacklist does not block emails, it simply serves as a running list of IP Addresses who are known for sending spam messages to users on the Internet.  It is a DNS-Based blacklist that gets updated frequently.  The ZapBL Blacklist takes recommendations for its administrators when compiling the list of IP Addresses.  It is known as a list of opinions from the administrations.  The administrators are not calling those on the blacklist spam, just simply classifying them as users that they do not want to receive email messages from.

How Did I Get Listed On The ZapBL Blacklist?

An IP Address or Domain Name can be listed if an administrator receives spam messages from them.  The listings can only be created manually by the administrators.  The ZapBL only takes recommendations from its administrators.  They do not allow outside, 3rd party opinions.  The administrators of the ZapBL Blacklist are completely confidential and are not released under any circumstance.

How Can I Remove Myself From The ZapBL Blacklist?

Most listings on the ZapBL Blacklist expire after a given amount of time.  Keep in mind, Administrators can flag certain IP Addresses or Domains to prolong their listing time.  They may also flag IP Addresses or Domains to prevent them from coming off of public blacklists.  If available, IP Addresses can be delisted by using the lookup tool.  If you do not see an expiration date and are not given the option to request to be delisted, you must contact the ZapBL Blacklist Organization for further information.  You may also check for express delisting with a manual review here.

How do I reduce my risk of getting onto the ZapBL Blacklist?

The best way to avoid getting listed on a blacklist is to engage in proper email practices such as...

  • Verify all email addresses before attempting outreach
  • Avoid sending unnecessary emails
  • Avoid the use of spam words within your email drafts
  • Keep your sending volume to a minimum (30-50 a day if your inbox has been warmed up with us for at least 30 days)

These blacklists are used as a reference by mail servers in order to determine how safe it is to accept messages coming from unknown domains and addresses.
