Blacklisted email addresses checker

A blacklisted email address checker is a tool that checks whether an email address is listed on a spam blacklist or not. Here are a few options:

  1. Sender Score: This is a free tool provided by Return Path that checks an email address against a list of known spam senders. You can enter the email address and get a score between 0 and 100, with higher scores indicating a lower likelihood of being spam.
  2. Spamhaus: Spamhaus is a well-known anti-spam organization that maintains a list of known spam senders. You can use their "Check IP" tool to check an email address against their list.
  3. Senderbase: This is a free tool provided by Cisco that checks an email address against a list of known spam senders. You can enter the email address and get a score between 0 and 100, with higher scores indicating a lower likelihood of being spam.
