As most email marketers know, you live and die by your IP reputation.
What is IP Reputation? All email must originate from an IP address. Each IP address has an associated score or IP reputation. Your IP reputation can be used to tell if a specific IP Address is responsible for sending Unsolicited Bulk Email, known as UBE or Spam. Your IP reputation can also be damaged by email recipients who click the spam button or complain about receiving an email that they never signed up to receive. Sending emails to non-existent email accounts will also hurt your IP reputation with most major ISP’s. ISP’s and email administrators can stop between 70-90% of all inbound connections from a simple query that shows if the IP reputation is in question or poor and if a specific IP address is being used to send spam, attempting to deliver email to an account that does not exist or is receiving an abnormal amount of complaints.
It is up to the person who owns that IP Address to be responsible for what comes out of that IP Address. If they don’t stop spam from originating from their IP, they can get a reputation for that behavior. Almost every large company, ISP and email server uses it to some extent; otherwise they would have to process almost 20 times as much email as they would without it.
There are many companies and resources that track that type of behavior, and create IP reputation lists. Often those lists are used to completely reject email coming from that IP Address. These lists are compiled from data that shows which IP Address is responsible for certain types of behavior. The following are some examples:
