What Causes An Ip To Get Blacklisted
Each blacklist has its own criteria when determining which mail servers to list. Those criteria can consist of several factors including technical listings, policy listings, and evidence-based listings.
- Technical listings occur because of mail server configuration issues .
- Policy listings happen because the receiving server does not wish to accept emails from certain countries, or ISPs, that have a history of not handling unsubscribe requests.
- Evidence-based listings are those where the server has received direct evidence that the sending IP address has been involved in sending unsolicited emails.
To protect their users from spam, mailbox providers carefully choose which blacklists they use. They assess whether an email is spam by analyzing several characteristics of the email, including the IP address it was sent from.
If the senders IP address is listed on a blacklist that the receiving mail server uses, the mailbox provider might filter the email as spam, bounce the email, or drop it entirely.

How Ip Gets To Blacklist Dns Servers
The most common way an IP or DNS to blacklist is by being compromised and used by a spammer to send out mass mailings. Once the IP is reported, it is added to the list of DNS blacklist servers. Another way an IP can get blacklisted is due to what is known as negative SEO. This occurs when a competitor uses malicious tactics to try and get your website penalized or banned by Google. If they are successful, your IP address could be added to a DNSBL.
Also, your website or mail server can get into the DNS server blacklist by mistake. This often happens when different projects are hosted on the same IP address, but one of them is engaged in spam or phishing. Then the spam DNSBL feeds list is replenished with all users who are hosted at this address. Sometimes you dont have to be a spammer or an intruder to get blacklisted by the DNSBL. When these situations occur, there are practical steps to take to resolve the issue.
Why Is Spam Blacklisted
It is important to understand that different people have different knowledge about spam. Spam is often referred to as unsolicited email. The purpose of malicious messages is to introduce malware, or viruses into your system. They usually come with a call to action that prompts you to do something that breaks the system.
Spam, on the other hand, is an email that you still need to sign in to but that you have yet to receive. These are not harmful to your computer but a nuisance to your inbox. Internet service providers and anti-spam vendors use spam filters or blacklists to prevent spam from entering their systems or networks.

What Blacklisting An Ip Address Means
The tool checks whether the given URL, IP address, or email server’s IP is listed with DNSBL. Email system providers utilize that database to filter out spam emails before they finally reach the end-users.
For example, if your company uses email marketing and you send out thousands of emails to promote your new product, some of the receivers mark that email as spam. There is a high chance that your IP will be on the IP blacklist, which needs to be avoided.
IP address blacklisting is the process or method to filter out or block the illegitimate or malicious IP addresses to access your network. It occurs when a web hosting company ultimately ignores your IP address. More precisely, any email you try to send is consequently blocked and filtered as spam.

What Is An Email Blacklist
A blacklist is a dynamic list of IP addresses that have been flagged for sending spam. Email service providers , free mailbox providers, and anti-spam vendors use artificial intelligence from blacklists to protect their users from spam and other malicious activity.
Your server IP address can be placed on a blacklist by:
- sending mail that contains viruses
- having a high spam-complaint rate
- sending to purchased/bad email lists
Do you know if your IP is blacklisted?
An internalblacklist is owned by a mailbox provider. For example, an IP could be placed on Gmails or Yahoos blacklist.
An external blacklist is owned by a third party. Mailbox providers may use an external blacklist to identify spammers. If your IP was listed on one of these lists, you would need to contact the third party for manual removal, rather than a mailbox provider who blocked you.
What To Do If Your Domain Is Listed
First, you need to make sure that whatever caused your domain to become blacklisted is no longer happening. There are a lot of possibilities, but be assured that blacklist providers won’t even consider delisting the domain unless you have a good idea of what caused it and that it is now resolved.
Second, you need to reach out to the blacklist provider who has blacklisted your domain and follow their mitigation process. There are many different blacklist/anti-spam providers and each one has their own process you need to follow. It is possible that you will need to get your hosting provider involved in both steps as you may be using shared hosting or acquired an already blacklisted domain/IP.
Lastly, follow best sender practices to avoid getting blacklisted again. Use double opt-in contacts, remove old and un-engaged contacts, and make sure your emails contain all the required info and unsubscribe methods. Check out our other blog posts that provide more details on best practices.

Every day, there are tens of billions if not hundreds of billions of spam emails sent per DAY. With the number of spam emails sent dwarfing the number of legitimate emails that are sent its no wonder Internet Service Providers and other organisation work so hard to prevent spam from being spread around.
With such a large number of spam emails sent, blacklists are created to try to combat this and block IP addresses and domains that are known to send spam.
Whenever an email is sent, the IP address is contained within it. An IP address is a unique string of digits used to identify the device or the server an email was sent from. Similarly, domain names are the websites name and can also be used to identify the website or organisation is was sent from e.g. @hubsell.com.
An email blacklist identifies and records, domains or IP addresses that have been sending spam, as per the standards of the blacklists owner. ISPs and mailboxes use them to protect their users from spam.

Now that I have clarified the definition of a blacklist and how it affects inboxing, lets explore the different types of blacklists and a few examples.

What Is An Ip Blocklist And What Does It Mean For Your Business
An IP blocklist is where a network blocks an IP address or domain name from sending emails to them because its suspected of sending out spam or malicious content.
Landing on an IP blocklist doesnt happen randomly. There are several ways you can end up on an IP blocklist, including:
- A huge growth in list size: Like anything done organically, a high-quality email list will grow over time, not overnight. If your email list suddenly grows by 100,000 subscribers overnight, this can set off alarm bells with your email and internet service providers. These alarms can lead them to believe that instead of acquiring subscribers organically, you have purchased a list of emailsleading to a blocklist. Using confirmed opt-ins is a great way to show that your subscribers are real and not spam, and adding other anti-bot tactics like reCAPTCHA to your sign-up forms signal your organic growth is legitimate.
- Spam complaints: If you send out poor-quality emails or fill up your subscribers inboxes with 50 emails a day, they may get annoyed and mark you as spam. And if your subscribers start marking your emails as spam regularly, it can lead to your internet service provider becoming wary of your email content or the quality of your email list. The more complaints your internet service provider gets from your subscribers, the better chance you will get blocklisted. Adding confirmed opt-ins to your mailing list can help prevent spam complaints.
