Did you know that over 20% of legitimate emails never reach their intended recipients? It's a staggering statistic that can have a significant impact on your business or personal communication.

The culprit behind this frustrating situation is an β€œEmail Blacklist.”

Now, you might be wondering, what exactly is an email blacklist? Simply put, it's a list of email addresses or domains that are flagged as potential sources of spam or malicious content. The email blacklists are also commonly known as DNSBL (Domain Name System-based Blackhole List) or RBL (Real-time Blackhole List).

Internet service providers (ISPs) and email filtering systems refer to these blacklists to decide which emails should be blocked or sent to spam folders. Being on an email blacklist can be a massive headache as it can lead to missed opportunities, damaged reputation, and decreased email deliverability.


If you're currently facing this issue, worry not! We are here to guide you through the process of email blacklist removal and reclaiming your rightful spot in people's inboxes.

We've done our research, gathered expert insights, and compiled a comprehensive guide that will walk you through the steps necessary to get off a blacklist. From identifying the blacklists you're listed on to implementing corrective measures, our blog will provide you with practical tips and proven strategies to regain control over your email deliverability.

How To Run An Email Blacklist Check?


One of the easiest ways to run an email blacklist check is to visit the websites of the most common blacklist vendors and check directly.

So, begin by visiting the websites of the most common email blacklist vendors. These vendors specialize in tracking and listing email addresses or domains that have been reported as sources of spam or malicious content.

Some popular email blacklist vendors include:
● Spamhaus
● Microsoft
● Proofpoint
● Barracuda
● Cisco/Ironport
● Invaluement
● Spamcop
● SURBL

You can also use various email blacklist lookup tools for email blacklist checks. These tools allow you to enter your IP address or domain name and run a search to check if you are listed on their blacklist. Simply input the necessary information, such as your email address or domain, and initiate the search.

If you’re looking for a free email blacklist checker you can try out tools like MXToolbox or BlacklistAlert.

MXToolbox provides a comprehensive set of tools for email and domain management, including an email blacklist checker. Simply enter your email address or domain, and it will scan multiple blacklists to see if you are listed.

BlacklistAlert allows you to check your email address or domain against multiple blacklists simultaneously. Enter your email or domain in the search box on their homepage to initiate the check.

Note: It's crucial to check multiple blacklist vendors since each vendor maintains its own blacklist database. By running checks on various vendors, you'll get a more comprehensive understanding of your blacklist status. Also, keep in mind that not all vendors provide public lookup tools, but the majority do.

Email Blacklist Removal: How do I remove my email from the email blacklist?


Let's dive into the detailed steps for removing your email from an email blacklist.

Diagnosing the problem


To be able to fix something you first need to learn the cause of it. Thus, the first step you should take is to identify the email blacklist that might have listed you and find out why.

● Identifying the Blacklists: As we have already mentioned in detail, you first need to do an email blacklist lookup and find out the email blacklist(s) that are affecting your email deliverability.

● Assess the Severity: Determine whether it's a single blacklist or multiple ones. The severity of the blacklisting will affect the steps you need to take for removal.

● Understanding the Reason For Email Blacklisting: Once you have identified the blacklists, it's crucial to understand why your email was blacklisted. Now the reason behind getting blacklisted can be technical or compliance-based. Some of the common reasons include:

β–  sudden surge in email sending volume occurs
β–  high spam complaint rates
β–  poor email list hygiene & sender reputation
β–  bad and spam-like content
β–  suspected malware

Assess and Address the Root Cause


Before going for delisting make sure you have addressed and solved the root cause of getting blacklisted. Simply requesting delisting without resolving the underlying issues that led to the blacklisting can result in repeated blacklisting in the future. Here's what you should do before requesting delisting:

● Review Sending Practices: Evaluate your email-sending practices and ensure compliance with anti-spam regulations. Consider factors such as the source of your email addresses, permission-based marketing, and frequency of email campaigns.

● Analyze Content Quality: Examine the content of your emails to ensure it is relevant, valuable, and doesn't contain suspicious or malicious elements that could trigger spam filters.

● Enhance Email Authentication: Implement email authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) to authenticate your emails and demonstrate sender legitimacy.

● Review Infrastructure and Security: Assess your email infrastructure and security measures to ensure they are robust and protected against potential compromises or abuse.

● Check Recipient Engagement: Assess the engagement levels of your recipients, including open rates, click-through rates, and spam complaint rates. Low engagement can indicate issues with your email campaigns or content that may lead to blacklisting.

● Monitor Feedback Loops: Implement feedback loops provided by ISPs to receive notifications when recipients mark their emails as spam. This helps you identify problematic campaigns or recipients who are not interested in your emails.

Requesting Delisting


Finally, comes the process of delisting. Each Email Blacklist has a different set of rules and methods. While some of them require a request for delisting some of the blacklists remove your domain automatically after a certain period of time.

Finding the delisting process for each blacklist:

Monitoring & following up on the delisting request:


After submitting the delisting request, monitor the progress and check your email deliverability regularly to see if your emails are still being blocked or marked as spam.

Delisting processes can take time, so be patient and allow the blacklist vendors to review your request. Follow their guidelines for any additional steps or actions they may require from you.

Follow up with the email blacklist vendor in case the expected waiting time increases. It might take some time but by following the right steps you will be able to get yourself off email blacklists.

Once you are off an email blacklist make sure you do not make the same mistakes again to avoid getting blacklisted again, else repeated blacklisting can be hard to deal with.

Best Practices to Avoid Blacklisting in the Future


Here are some of the best practices that will drastically reduce the chances of getting marked by email blacklists again.

Building an Email List Organically


Building an email list organically ensures that you have engaged and interested subscribers who willingly provide their email addresses. This drastically reduces the chances of getting flagged while maintaining a good sender reputation and deliverability rate. Here are some effective techniques to organically build email lists:

● Lead Magnets: Create valuable resources such as e-books, guides, free PowerPoint templates that resonate with your target audience. Then, offer these resources to your visitor in exchange for joining your email list.

● Webinars and Events: Host webinars or virtual events on topics relevant to your audience. Encourage participants to sign up for your email list during registration.

● Double Opt-In: Implement a double opt-in process, where subscribers confirm their email addresses by clicking a verification link sent to their inbox. This confirms their consent and improves the quality of your email list.

Real-Time Email Verification


Real-time email verification process acts as a crucial shield that ensures your messages reach the intended audience and maintain a positive sender reputation.

It helps you avoid spam form submissions and invalid, or outdated email addresses out of your system. This proactive step helps to lower bounce rates, as your emails reach valid recipients, and reduces the likelihood of spam complaints.

Hence, by ensuring the integrity of your email list through real-time email validation tools like Clearout.io, you protect your sender reputation, enhance deliverability, and ultimately prevent your emails from being blacklisted.

Clearout.io employs advanced algorithms to identify invalid or non-existent email addresses, disposable or temporary email domains, and potential spam traps. It also cross-checks against known blacklists to ensure your emails won't be blocked or marked as spam.

With email validation, the tool helps you remove risky and invalid addresses, reduce bounce rates, protect your sender reputation, maintain high deliverability rates, and avoid blacklisting by ISPs to a great extent.

Monitoring Email-Sending Practices and Volume


Monitoring your email-sending practices is crucial to prevent blacklisting. Following such practices ensure that your emails and activities do not look like spam, and you stay off the hook of getting blacklisted. Here are some of the most important things to consider.

● Warming Up the Email: Never send out large volumes of email, when starting a new email campaign or using a new email server, or else your ISPs might mark you as spam. Instead, gradually increase your email sending volume. This gradual approach helps establish a positive reputation with ISPs and avoids triggering spam filters.

● Avoiding Spam Words and Triggers: Be cautious of using words and phrases that are commonly associated with spam. Spam filters are sensitive to elements such as excessive capitalization, excessive exclamation marks, and misleading subject lines. Keep your content relevant and free of suspicious language.

● Initial Non-Promotional Emails: Nobody wants to have hundreds of irrelevant promotional emails spamming up their inboxes. Start with sending non-promotional emails such as newsletters, industry updates, or helpful resources, and then turn towards sending personalized emails that cater to your audience’s pain points. This approach allows recipients to engage with your emails positively, improving your sender's reputation.

● Regular Monitoring: Another important step to avoid getting blacklisted in the future involves analyzing campaign performance and reading the signs that might take you toward getting blacklisted. Thus, you should keep an eye on email metrics like open rates, click-through rates, spam complaints, unsubscribe rates, etc, and take necessary action to maintain a healthy score.

Also, focus on maintaining email list hygiene by regularly removing invalid and inactive subscribers. Stay updated with industry best practices and changes in email deliverability policies to remain compliant and promptly address any issues that arise to maintain a positive sender reputation.

Following all of these practices after email blacklist removal will surely save you from getting flagged again.

Take Action To Remove Email From Blacklist


Being blacklisted can have a devastating impact on your email deliverability. If you find yourself in this situation, it is important to act quickly to get removed from the blacklist.

Following the steps along with the best practices mentioned above will help you get off an email blacklist & stay away from blacklists in the future as well!
