Have your emails been ghosting you lately?

Landing in the dreaded spam folder or, even worse, not reaching their destination at all?

It’s the digital equivalent of shouting into the void, and it’s frustrating, especially when you don’t know the cause. But what if I told you there’s a shadowy list out there that might be holding your emails hostage?

It’s called an email blacklist, and if your IP or domain is on it, your messages could be getting blocked before they even have a chance. But don’t despair! In this guide, we’ll unravel the mystery of email blacklists, explore the telltale signs that you’ve been blacklisted, and most importantly, guide you step-by-step on how to break free. Stick around, and let’s turn those digital echoes into clear, resonant messages once again.

What Is An Email Blacklist?

Blacklisting, often interchangeably referred to as “blocklisting,” is a mechanism employed by an email service provider (ESP), security companies, and non-profit organizations to combat the pervasive issue of spam emails. At its core, an email blacklist is a list that contains IP addresses, domain names, or even specific email addresses that have been identified for sending spam messages or malicious content.

In email marketing, bypassing spam filters is vital to avoid the junk folder or landing on an email blacklist, which flags your IP or domain for potential spam activity.

Nature of Blacklists:

There are various types of blacklists, each serving a specific purpose and maintained by different entities:

  • Internal Blacklists: Managed by webmail providers like Gmail, Outlook, and Yahoo. These are proprietary lists that these providers use to filter out spam for their users.
  • External Blacklists: Managed by security companies such as Proofpoint, Barracuda, and Cloudmark. These lists are often used by businesses and organizations to filter incoming emails and protect their networks from threats.
  • Non-Profit Blacklists: Managed by non-profit organizations like Spamhaus and SURBL. These lists are widely respected and utilized by many Email Service Providers globally.

How To Remove Your IP or Domain From a Blacklist?

Finding out that your IP or domain has been blacklisted can be alarming. However, you can navigate the removal process effectively with the right steps. Here’s a step-by-step guide to help you get off a blacklist:

Identify the Blacklist

Blacklists, maintained by various organizations, each have unique criteria and processes for listing and delisting. Understanding which specific blacklist you’re on is vital for two primary reasons. Firstly, it allows for a tailored removal request, given each blacklist’s distinct criteria. Secondly, the impact on your email deliverability varies; being on a major blacklist can be more detrimental than a lesser-known one.

MailGenius ‘Free’ Email Blacklist Checker

Before you can address the issue, you need to know which blacklist(s) you’re on. MailGenius can help you check your domain or IP against known blacklists.

MailGenius helps email senders pinpoint potential deliverability issues before dispatching their emails. By sending a test email via MailGenius, you’ll be entering your IP address or domain to check the status of your mail server’s IP address on more than 100 DNS based blacklists, providing a comprehensive report on your listing status. Beyond this initial check, it’s advisable to regularly monitor your domain or IP, ensuring you stay ahead of potential issues. With a clear understanding of your blacklist status, you’re better equipped to address the underlying cause and liaise with the appropriate entities for removal.

Contact the Blacklist Operator

Once you’ve identified that your IP or domain is blacklisted, the next crucial step is to reach out to the blacklist operator. These operators maintain the lists and can remove your IP or domain from them. Here’s how you can approach this process:

Step 1: Visit the Blacklist’s Official Website

Every reputable blacklist will have an official website or portal. This is your primary source of information on their removal process.

For instance, if you find your IP listed on Spamhaus, navigate to the Spamhaus website. They provide detailed information on why you might have been listed and the steps to request removal.

Here are some of the main blacklist removal request URLS provided by

RBL / Blacklist Removal Request URL
Abuseat CBL
Backscatter Blacklist
Barracuda Blacklist
Invaluement Blacklist
LashBack UBL
SpamCop Blacklist
Spamhaus Blocklist
Sorbs Blacklist
Truncate Blacklist Automatic Only
UCE Protect Blacklist

Step 2: Look for the Removal Procedure

On the website, search for terms like “delisting,” “removal request,” or “de-blacklisting.” This will typically lead you to a page or section detailing their removal process.

Some blacklists, such as Barracuda, offer a “Lookup & Removal” section where you can check your IP’s status and request its removal if listed.

Step 3: Understand the Specifics

Each blacklist has its unique removal procedure. Familiarize yourself with their specific requirements to ensure a smooth delisting process.

Spamhaus has specific forms for different types of listings. Whether you’re listed due to spam or due to a network issue, you’ll need to fill out the appropriate form.

Step 4: Prepare Your Request

Send an email to the support team of the site whose blacklist you are on.

Some blacklists require detailed information about the corrective actions you’ve taken since being listed. Be transparent and thorough in your explanation.

If you were blacklisted due to high spam complaints, detail the steps you’ve taken to clean your email list, the measures implemented to ensure explicit consent from recipients, and any other relevant actions.

Explain in detail what happened and what actions have been taken to resolve the problem. Once the problem has been fixed, you will be taken off the list automatically.

Step 5: Follow Up

After submitting your removal request, it’s essential to monitor your status and follow up if necessary. Some blacklists might provide a timeline for review, while others might require additional information.

If you’ve submitted a removal request to SpamCop and haven’t received feedback within their specified timeline, consider reaching out for an update.

Blacklist operators value transparency and responsiveness. If they reach out with questions or require further information, be prompt and cooperative in your response.

Main Reasons For Being Blacklisted

Each blacklist will typically provide a reason for the listing. This could range from spam complaints to technical misconfigurations. Understanding the root cause will guide your remediation efforts.

Here are a few main reasons why you are blacklisted.

Recipient Complaints

One of the most common reasons for being blacklisted is a high volume of recipients marking your emails as spam. When users frequently report your emails, it signals to ESPs that your content might be unwanted or intrusive.

For example, a company sends out a weekly newsletter. However, due to a sudden change in content or frequency, a large number of recipients mark the emails as spam. This spike in complaints can lead to blacklisting.

Using email lists that haven’t been acquired organically or with proper consent can lead to a surge in unsolicited emails. Such practices are frowned upon and can quickly land you on a blacklist.

Spam Traps

Spam traps are a tool used by Internet Service Providers and blacklist operators to identify and monitor potential spammers.

These are email addresses specifically designed to catch spammers. They might be old, recycled email addresses or ones created solely to identify and block spam. If you send emails to these addresses, it’s a clear indication that you’re not following best email practices.

For example, an online store sends promotional emails to an old list that hasn’t been cleaned in years. Several of these addresses are now used as traps set up by ESPs. Hitting even a few of these can lead to immediate blacklisting.

You can find ways to avoid spam traps here.

Fix The Issues

Being blacklisted is often a symptom of underlying issues with your email practices or technical configurations. To ensure successful delisting and prevent future blacklisting, it’s essential to address the root cause.

Here’s a breakdown of how to fix blacklisting issues for the most common reasons.

Spam Complaints

If many recipients have marked your emails as spam, signaling to ESPs that your content might be unwanted or intrusive, ensure your email content is relevant, valuable, and adheres to best practices.

The CAN-SPAM-ACT outlines the proper way to send emails; not adhering to it increases the chance of emails being marked as spam. Here are some guidelines and best practices.

  • Avoid using misleading subject lines or spam words: Instead of using a spammy subject line like “Earn $$$ Now!”, opt for a more transparent and relevant subject like “Exclusive Savings for Our Subscribers.”
  • Opt-in and Opt-out Mechanisms: Make sure you have clear mechanisms for users to subscribe and unsubscribe from your emails. This ensures that only interested recipients receive your communications. Include a visible “unsubscribe” link at the bottom of your emails and ensure the process is straightforward and immediate.
  • Malicious Content: If your emails or website have been associated with distributing malware, phishing attempts, or other malicious activities, you will be blacklisted. Regularly scan your website and any email attachments using reputable security tools to ensure you’re not inadvertently hosting or sending malicious content. If you often send PDF attachments in your emails, ensure they are scanned for potential threats before dispatching.

Cleaning Spam Traps

If you’ve hit a spam trap, it’s a clear indication that there are issues with your email list management or acquisition methods. Here’s how to clean them:

Reconfirm Your Email List:

Send out a reconfirmation campaign to your entire list, asking recipients to confirm their interest in continuing to receive your emails. This can help weed out any potential spam traps or unengaged subscribers.

Implement Double Opt-In:

Ensure that all new subscribers confirm their subscription through a two-step process. This not only verifies the email address’s validity but also ensures that the subscriber genuinely wants to receive your emails.

Regularly Clean Your Email List:

Remove inactive subscribers and those who haven’t engaged with your emails in a long time. Regularly cleaning your email list reduces the chances of hitting recycled spam traps.

Signs of Being Blacklisted

A sudden spike in email bounces can be a telling sign of blacklisting issues. For instance, if your usual bounce rate of 2% unexpectedly jumps to 20% or higher, your emails will likely face rejection due to being on a blacklist. Additionally, even if your emails have consistently reached recipients’ inboxes in the past, finding them redirected to the spam or junk folder can indicate blacklisting. Imagine a scenario where a weekly newsletter, once reliably landing in the primary inbox, is now consistently relegated to the spam folder.

Another clear indicator is receiving delivery failure notifications. Many email systems provide feedback when an email doesn’t reach its intended recipient. For example, after dispatching a promotional email, you might be inundated with automated responses, highlighting that your email was undelivered because a specific blacklist flagged it.
