Is your IP address on a Blacklist?
Find out with Blacklist Lookup.
Reputation Network Blacklist Lookup
Return Path hosts a widely used and highly accurate blacklist, which is an official list of email server IP addresses that show activity resembling the activity of spammers. If your email server’s IP is on a blacklist, it doesn’t mean you're a spammer. However, a blacklisted IP is receiving bad reputation metrics from one or more legitimate Reputation Network sources.
Blacklisting is based on real time data compiled through Return Path’s cooperative Global Reputation Network. The Return Path Global Reputation Network Blacklist calculates the probability that emails from a particular IP address may be unwanted based on measurements of unwantedness.
Reputation Network Data does not evaluate the content of an email message. Instead, the evaluation is based on the percentage of email messages from a particular IP address that are considered unwanted or "spam" by individual recipients as well as email providers and filters through a variety of actions including, but not limited to, complaints, unusual volume patterns, and emails sent to spamtraps and unknown email addresses.
