Email Block List


What is an Email Blocklist?

An email blocklist (also known as an email blacklist) is a list of email addresses, domains, or IP addresses that are identified as sources of spam or malicious content. Internet service providers (ISPs), email service providers, and organizations use blocklists to filter out unwanted or potentially harmful emails before they reach users’ inboxes.
