Even if you don’t know what an email blocklist is, you’ve most likely been on one. If your email provider uses a spam filter, chances are high that your email address has been blocklisted by Spamhaus at some point.
For most businesses, being on a blocklist can be quite damaging. Many ISPs will refuse to allow customers to send emails from blocklisted addresses, and many businesses have suffered severe damage as a result of being blocklisted — even going out of business entirely.
Bulk email services are often used by businesses to send commercial emails without getting permission from the recipients. This is termed spamming. If you own an email service, you can be sure that your IP address will get listed on the Spamhaus blocklist if you engage in this activity. However, if your email is already on the blocklist, there are ways to successfully go about a Spamhaus delist.
What Exactly Are Email Blocklists?
Email blocklists are lists of IP addresses, domains, and email addresses that have been identified by ISPs or other organizations as sources of abusive activities. Your IP address or domain may be on an email blocklist if your ISP has received complaints about you. This could be due to someone reporting you for spamming, phishing, malware distribution, or hosting illegal content.
Indeed, some spam emails are used to spread harmful content, and these types of threats gravely affect millions of unsuspecting users worldwide. Some businesses do resort to unethical means, while some get blocklisted by accident. That is why an international non-profit organization called Spamhaus has a mission to identify possible cyberattacks by providing a blocklisting service for email senders who may be involved with sending out malicious emails.
What Is the Spamhaus Zen Blocklist?
ZEN is one of the blocklists managed by the Spamhaus Project to keep its blocklisting system robust. It combines all other blocklists by Spamhaus to create one comprehensive, reliable tool for looking up an IP faster and identifying which ones should be on the list.
The Spamhaus Block List (SBL), on the other hand, is a collection of all IP addresses that Spamhaus has banned due to having been involved in creating, hosting, or sending out unsolicited bulk emails.
The Spamhaus ZEN blocklist is one of the world’s most trusted and comprehensive spam lists. It is used by all email providers to block spam and phishing emails. It also blocks malware, botnets, ransomware, as well as domain name servers (DNS), and websites that serve malicious content.
To avoid being blocklisted by Spamhaus, it is important to understand what circumstances lead to an IP being blocked. If you are a legitimate business owner and want to keep your IP address off of Spamhaus’ list of blocked domains, it will be useful to know how to complete a Spamhaus blocklist removal to remove your IP from their list.
Why Did Spamhaus Blocklist My IP?
A Spamhaus blocklisting can be a nightmare for any business owner. Whether you’re on the receiving end of an email marketing campaign or if your website is being attacked by a hacker, being blocklisted can have serious consequences that will also affect every aspect of your business.
Being blocklisted on Spamhaus means that no standard email servers will accept emails from you because you’re considered to be a source of spam. Here are some of the factors why Spamhaus might have blocklisted your IP.
Exceeded Email Threshold
In the email marketing industry, it’s unethical to flood your subscribers’ inboxes for promotions. If you send more than what’s necessary, this can make your emails land in spam folders and prompt ISPs to add your address to the blocklist. This means that not only will your emails stop showing up in your subscribers’ inboxes, but they’ll also be unable to receive any future emails from you.
Flagged Email Content
As part of the digital marketing strategy, emails can be used to send important updates, newsletters, or promotions to customers. When utilizing email for these purposes, it is easy to make mistakes that will hurt the company’s reputation rather than elevate it. Business owners can easily make the mistake of using flag-worthy keywords in their email campaigns (e.g., money-back guarantee, absolutely free, all caps, multiple exclamation marks, etc.), which can easily get them blocklisted.
Poorly Managed Email List
When users send unsubscribe requests, the business should take action right away. Otherwise, this can lead to getting blocked because your company may still be continuing to send emails even when the recipient has already requested to be removed from your mailing list. If your list is full of inactive subscribers or non-responsive leads, it can lead to blocklisting by ISPs and email providers.
How Do I Get Out of the ZEN Blocklist?
Banned email addresses can be a serious problem for any business. Being on the blocklist means your emails will never reach the inboxes of possible customers and clients. They may bounce back to you with a notification saying that your account has been banned from the server.
If you have been blocklisted by the Spamhaus ZEN blocklist, your goal is to get off of this list as quickly as possible so that you can start sending out emails again. Here are the steps for a successful Spamhaus ZEN delist.
Investigate the Cause
Once you’ve learned about blocklisting, it is best not to delay. Stop sending emails at once. Look up your details to know which Spamhaus ZEN delist IP address and domain are affected. Check your emails for signs like inactive IDs and bounce notifications. Figure out if you’ve violated any policies, which may have triggered the blocklisting.
Ask for Help
Talking to the right people is important at this stage because it gets you the expert advice that you need. Seek the assistance of your technical account manager to know exactly how to handle the Spamhaus delist. Inform the right people who have direct involvement in your email activities, such as your email service provider. Let them identify the root cause to determine what the next course of action should be.
Find Solutions
Continue working with your technical account manager once you’ve identified the cause of the blocklisting. Remove all IDs that are inactive or may have bounced — they are vulnerable to spam traps, which in turn trigger the spam alerts. Ask your email service provider to send an unknown user code, which will then give you your contact list revealing the things you should remove.
Submit Your Request
Once you have done all the steps above, it’s time to request the Spamhaus delist. Fill out the form on their site and follow all instructions. Provide a concise description and mention the steps you’ve taken to fix the issue. Remember that submitting a delist form is not a guarantee your details will be removed from the blocklist right away. Spamhaus will make the decision and inform you once they have removed you from the list.
Best Practices To Stay Out of Blocklists

- Use double opt-ins: With a double opt-in newsletter subscription, users who sign up for a mailing list will receive a link in their email to verify their subscription. This creates an added layer of security to ensure that your subscribers are real people.
- Add an unsubscribe link: With an option to unsubscribe, this ensures you’re adhering to anti-spam laws and providing a great user experience, not simply sending emails without their consent.
- Clean email lists: Identify potential spam traps like unresponsive subscribers, which may trigger accidental blocklisting if they receive your emails.
- Optimize content: Use personalized email content to avoid being flagged. Use reputable marketing software to create unique designs and valuable information to provide your subscribers.
- Set up security: Secure your servers to protect them from malware or bots that send fake emails, which can hijack your IP address and easily cause blocklisting.
- Prevent typos: Do not manually enter email addresses. Doing so runs the risk of typos, which often cause emails to bounce when sent to nonexistent addresses. Lead users to a landing page that allows them to opt-in, minimizing saving incorrect email addresses.
