Is My Domain Email Blacklisted

Don't Miss

What The Spam Blacklist Checker Does

Find Out If Your IP Address or Domain Name is Blocked or Blacklisted

The Spam Blacklist Checker queries the following using the provided domain name or IP address to see if there are any matching results:


All of these lists use different data sets and methods for identifying problematic senders, so a domain name/IP address may appear on some, but not all lists. Furthermore, these lists do not block messages they provide information to email servers which do block messages from what appear to be spammers.

Though you can search the records with domain names, spam blacklists use IP addresses only changing the domain name while keeping the IP address will not change the results.

How To Check If Your Domain Is On A Spam Blacklist

The worst nightmare of an email marketer is to find themselves on a blacklist. Unfortunately, even if you run clean marketing with a subscriber base collected legally, your domains IP address can still get blacklisted.

The good news, however, is that the problem can be fixed. More importantly, you can avoid it in the first place by regularly validating your contact list. The topic is complex and might be overwhelming, so Id recommend first checking what Brian Minick, COO of ZeroBounce Email Validator, has to say about maintaining a healthy contact base hygiene.

Next thing you need is a domain spam check: see whether your website is currently on the list. There are a number of services you can use to do it:

For example, in Spamhaus, go to Blocklist Removal Center > Domain Lookup Tool and enter your domains name. Youll get instant result.

You may use other services. The procedure will be the same.

A Sudden Increase In Email Volume

This is a common mistake that almost all new marketers do. Shooting up of your email volumes is an alert sign that you are sending emails to an email list you didnt build on your own but have acquired it in bulk from some external source. Simple logic- How come you got so many subscribers in a single day?

With that said, the industry is now in more control of the email blacklist than you can ever think. They are using DNSBL services and even have their own rules for blacklisting.

The DNSBL service is not just a constantly updated directory of domains, but more of a software environment that works in close conjunction to the ISPs DNS that is responsible for mapping your IP address to Domain name and vice versa.

Is that a need to worry? We have just looked at a scenario when you are listed on the blacklist but not how it is seen by multiple services that use it.

Now with your domain/IP being blacklisted, does everything stop? Can you only send emails after being delisted? it depends. To answer that question we need to look at how the MSP and ISP work with DNSBL and deal with emails from blacklisted domain and IPs.

Why Is My Ip Address Blacklisted

A blacklist is a database of IP addresses that are believed to send spam. Emails from these IP addresses are either blocked or routed to the recipient’s spam folder or handled accordingly.

Your IP may be in a single blacklist or multiple backlists. There is no centralized authority for that. Each blacklist is managed independently, and each has its criteria for listing or delisting the IP address in its blacklist.

There are several reasons that your IP is on the blacklist.

  • The main reasons for IP blacklisting are the virus, malware, and sending many spam emails.
  • If you run a mail server that is not configured correctly, which results in sending spam, or you intentionally send spam, then definitely your IP address becomes blacklisted.
  • Maybe you tried to purchase the email lists from a third party containing many incorrect or spam email addresses.
  • The majority of the email receivers mark your email as spam.
  • Someone hacked your email account and using it for spammy activities.
  • There is also a scenario that your IP is on the blacklist even you did not do anything wrong. That frequently happens when having a DHCP IP address. Most of the blacklist maintainer automatically adds the IP address that is assigned via DHCP by ISP. Even though you are not a spammer, maybe the person who had your IP address before you, using it for spamming activity. Only your ISP knows who had that IP address before assigning it to you.
  • Your website is suspected of being used for hacking purposes.

  • Why Do Domains Get Blacklisted And How To Delist Them

    Have you ever wondered what is the solution for the modern spam epidemic? Blacklists are the answer! Learn more about what they are, why do domains get on blacklists and how to get a domain off a blacklist.

    What is a Blacklist?

    Depending on the source, the amount of daily spam emails being sent is anywhere between 80 to 95% of all emails sent on the internet that day. With such large numbers, most experts agree that manually sorting through your inbox to get rid of spam has become highly inefficient. As such, public blacklists of mail servers and IP addresses have been created to prevent repeat offenders from relaying spam.

    A blacklist is a list of blocked domains, email addresses or IP addresses. When a website gets on one of these lists, users can no longer access the site directly and servers that use these blacklists will block emails from the domain .

    The operators of some of the biggest blacklists, Spamhaus have created this chart to make it easier to understand how and when the blacklist interacts with the email:

    There are public blacklists, which as the name suggests, are available to everyone to filter email, while private blacklists are maintained by third-party organizations. To find out more about domain blacklists, read our article on what are DNSBLs .

    What Does Being Blacklisted Mean For Your Email Campaigns

    However, there are hundreds of blocklists, and not all of them have the same impact on email programs. So rather than panicking if your IP or domain pops up on any blocklist, check if it is an important blocklist and determine if your performance metrics are impacted.

    Types of public blocklists

    IP-based blocklists are used by mailbox providers to identify which IP addresses are sending spam or other bad mail, such as malware infectors, virus and botnet distributors, to their receivers.

    Domain-based blocklists utilize the senders domain names to create lists of domains associated with spam. These domains arent necessarily sending spam to receivers, but they were found to be using bad practices associated with spam attempts. Make sure to follow email best practices when creating email campaigns.

    Not all blocklists are created equal. Some blocklists have a bigger impact on performance.

    If youre blocklisted, there are steps you can take to address mitigating factors that led to your IP or domain being blocklisted. Temporarily stop your email campaigns and figure out exactly how and why this happened. If youre on a critical blocklist, like Spamhaus, follow their delisting process.

    How Can You Check If Your Ip Is Blacklisted

    You wont get a notification that your IP is blacklisted. Instead, youll need to take action to find out. Here are a few ways you can tell:

    • Check a blacklisted site directly. Many blacklists are openly available, such as net. If you want to see whether your domain is being blocked by a specific site, you can search by that site either the IP address or domain.
    • Use a dedicated blacklist tool. You can perform a blacklist check on the MXToolbox. There are a number of free, online tools that you can use to check domain and IP address blacklists. There are a number of blacklists so each tool may not have access to all of themyou should check on more than one site.
    • Check your metrics. If your open rates have gone from 30% to 5%, you know something has happened that goes beyond the content of your emails. While this isnt definitive, its a good sign that something along the way is causing your emails to be dropped. This could be blacklisting, failed authentication, or other issues.
    • Send test emails. Send test emails out to a list of known email addresses and see how many of them are received and whether they end up moved to the spam folder. Test emails will show not only whether emails are being delivered but how theyre being delivered.
    • Use an email monitor. A built-in email monitor, such as the MassMailer Email Monitor, will check blacklists automatically when you send emailsproviding you with the fastest, most actionable information.
