Bussiness 24 Jan, 2021

Each blacklist database has its own criteria for flagging IP addresses and compiling your own list of online criminals. Those criteria could include a variety of technical, policy, and evidence-based “lists.”

  • < h4 style="box-sizing: border-box; clear: both; font-family: Raleway, sans-serif; color: #202020; font-weight: 500;">Technical lists are mainly produced due to configuration issues server, such as missing or incorrect reverse DNS records, missing or incorrect banners, and mail servers operating within a suspicious range of IP addresses.
  • Policy lists are based on a carrier not wanting to receive emails from certain countries, or ISPs, who have a history of not honoring "unsubscribe" requests.

  • Evidence-based lists are those where the operator has received direct (or indirect) evidence that an IP address has participated in sending unsolicited emails

  • Self-Service Removal. There are some blacklists with a self-service removal feature that allows you to remove your IP address from the list without much hassle. However, you&;#39;ll want to make sure you&;#39;ve resolved any issues before doing so.

  • Time-based removal. Most blacklists have a built-in automatic process that removes lower-level lists (IP addresses that are light offenders) in one or two weeks. But if the address IP has spammed more than once or if it is high volume, the time period will be longer.

  • Follow their rules

If you are truly innocent of any deliberate wrongdoing (or if you made an honest mistake), let them know. The more open and direct you are With a listings database, the easier it will be for your IP address to be removed from the blacklist.

    Keep these tips in mind:

    1. Your priority is to reduce spam on your email platform for your customers, your goal is not to prevent you from sending emails.

    2. Spam is a serious problem. They don&;#39;t blacklist lightly. It&;#39;s their way of trying to identify and prevent real problems.

    3. Blacklists are legal because they are designed to prevent fraud or other activity that disrupts normal business. We all need to accept that fact.

    4. If you made a mistake and were blacklisted, don&;#39;t make the same mistake again. You probably won&;#39;t be forgiven a second time.
