    What are Email Blacklists?

    Email blacklists are databases of IP addresses and domains that have been identified as sources of spam, malware, or other unwanted email. Email providers use these lists to filter incoming mail.

    Types of Blacklists:

    IP BlacklistsBlock specific IP addresses known for sending spam
    Domain BlacklistsBlock domains used in spam or phishing campaigns
    URI BlacklistsBlock URLs commonly found in spam messages

    Impact on Email Delivery:

    Being listed on a blacklist can severely impact your email deliverability, causing legitimate emails to be blocked or sent to spam folders.
