The numbers are eye-opening – only 79.6% of emails actually reach their intended inboxes in 2023.

Email delivery faces serious challenges. About 4.1% of messages end up in spam folders, and 16.3% disappear completely from the digital world. Your domain might be blacklisted if you notice your email deliverability recovery attempts aren’t working.

A blacklisted domain has been flagged by email servers, search engines, or anti-spam databases because it’s considered harmful or malicious. This situation typically occurs after your domain gets linked to spam, malware, or other suspicious activities.

Your overall deliverability depends on three key elements: infrastructure, content, and reputation. You should look into your email sender reputation if your messages still don’t reach inboxes even with resilient infrastructure.

Here’s the bright side – we’ve created a detailed guide to help you identify, fix, and prevent email deliverability issues. We’ll guide you through every step of email blacklist removal, from checking your status to rebuilding your domain’s email reputation.

Are your emails stuck in spam folder purgatory? Let’s take a closer look at the solution!

Step 1: Confirm Your Domain Is Blacklisted

You need to verify if your domain is actually blacklisted before trying any fixes. Red flags pop up when emails keep landing in spam folders or bounce back completely.

Check domain and IP using blacklist lookup tools

The first step is to check your domain’s status with specialized blacklist lookup tools. Here are some reliable tools you can use:

• Spamhaus – Head to their Blocklist Removal Center > Domain Lookup Tool and type in your domain name
• MX Toolbox – Tests your mail server IP addresses against more than 100 DNS-based email blacklists
• Sender Score – Reviews your overall sender reputation
• UltraTools – Gives you a detailed blacklist check
• EmailListVerify – Checks various blacklists live

These tools work in a straightforward way – just enter your domain or IP address and you’ll get instant results.

Look for bounce codes and spam folder placement

Bounce codes give you solid evidence of blacklisting. The recipient’s server sends an automated Non-Delivery Report (NDR) with specific numeric codes when emails fail to deliver.

Codes that start with 4 usually point to soft bounces (temporary issues), while those beginning with 5 indicate hard bounces (permanent failures). To cite an instance, bounce code 5.7.1 means “Delivery not authorized, message refused” – a clear sign that you’re blacklisted.

Spam folder placement raises another red flag. Your domain might be blacklisted if open rates suddenly drop or complaints go above 0.1%.

Identify which blacklist(s) flagged your domain

After confirming your domain is blacklisted, you need to find out which blacklists have flagged it. This information helps you make targeted removal requests. Tools like MXToolbox and multiRBL.valli.org let you check multiple blacklists at once.

Most blacklist checking services show you:

• The specific blacklists that flagged your domain
• Why you might have been blacklisted
• Where to go for removal

This detailed verification gives you a clear starting point to recover your email deliverability before taking any fix-it steps.

Step 2: Fix the Root Cause of Blacklisting

My domain’s blacklisting requires me to understand why it happens. Email service providers monitor specific red flags that can trigger blacklisting of my domain.

Remove malware or suspicious content from your site

Malware infections can turn my website into a spam-sending machine without my knowledge and get it blacklisted. Here are three ways to clean malicious code:

• Use security plugins: Automated security tools can spot and remove hidden malware with one click
• Manual cleaning: This requires checking suspicious files, code review, database cleanup, and removing backdoors with keywords like eval, base64_decode, or gzinflate
• Professional services: Security experts can detect complex malware that automated tools might miss

Audit your email list for spam traps and bounces

Spam traps are non-active email addresses that catch irresponsible senders. A single trap hit can reduce deliverability by up to 50%. Your email list also needs good maintenance since high bounce rates alert email providers immediately.

Your list hygiene should include:

1. Remove invalid or outdated addresses right away
2. Look for suspicious patterns – zero engagement segments often hide spam traps
3. Monitor reply rates instead of opens, since traps never reply or click

Check for compromised accounts or unauthorized access

You can spot compromised email accounts through these signs:

• Suspicious inbox rules that automatically forward emails
• Missing or deleted emails and unusual activity
• Messages in sent items the account owner didn’t send
• Login problems

Review recent email campaigns for spam triggers

Your email content might trigger blacklisting through:

• Too much promotional language or misleading subject lines
• Bad HTML formatting or heavy image use with little text
• Authentication issues with SPF, DKIM, or DMARC records
• Quick increases in email volume without proper warm-up

These steps are the foundations for my email deliverability recovery plan.

Step 3: Submit Email Blacklist Removal Requests

The next priority after fixing why it happens is getting off those blacklists. Each operator has their own way of doing things, so you need the right approach for each one.

How to request removal from Spamhaus, Barracuda, and others

Spamhaus removal needs these steps:

• Visit their IP and Domain Reputation Checker tool
• Enter your domain and do what it tells you
• Find the “Contact the SBL Team” link at the bottom of your listing page

Barracuda delisting wants you to fill out a form with:

• Your email server’s IP address
• Your contact details (email and phone)
• A clear reason why they should remove you

Barracuda usually handles these requests within 12 hours if you give them everything they need.

Microsoft/Outlook users can use their sender support portal or send an email to delist@microsoft.com with complete NDR headers. They usually get back to you in 24-48 hours.

What to include in your delisting request

Your removal request needs:

• A clear explanation of what got you blacklisted
• What you did to fix it
• Proof that you fixed things (screenshots, logs)
• Your promise to stick to good practices

Vague stories or trying to blame others will get your request denied. These blacklists want technical details, so put everything important in your first message.

How long removal takes and what to expect

Each provider has their own timeline:

• Spamhaus takes 24-72 hours for real requests
• Barracuda needs about 12 hours with proper details
• Microsoft might take 3-5 business days
• SpamCop usually clears you in 24 hours if you fixed the issue

After you submit, keep checking your blacklist status with the same tools as before. Need a reliable email solution while you sort this out? You can sign up at https://app.campaignhq.co/signup/ to manage your campaigns better.

Tips for successful email blacklist removal

Here’s how to get off blacklists faster:

• Send just one request per blacklist – multiple ones might get ignored
• Keep your communication professional and honest
• Give them all the information in one go
• Watch out for new blacklistings during this time
• Have a backup sending system ready if possible

Step 4: Rebuild and Monitor Your Email Reputation

Your battle isn’t over after getting removed from blacklists. You need proper authentication setup and constant monitoring to rebuild your domain’s email reputation.

Set up SPF, DKIM, and DMARC correctly

Email authentication protocols work as digital verification systems for your messages:

• SPF verifies authorized sending servers
• DKIM adds cryptographic signatures to confirm authenticity
• DMARC tells receiving servers how to handle messages that fail authentication

The right setup of these protocols together stops email spoofing and boosts deliverability by up to 10%.

Use email warmup strategies to restore trust

Domain warming helps you build positive reputation with mailbox providers. Start with your most engaged subscribers, then add older segments in 15% increments. This step-by-step approach helps you avoid spam filters while rebuilding trust.

Track your sender reputation score regularly

Your Sender Score needs regular checks through tools like Validity Everest or Sender Score website. This score shows how mailbox providers rate your trustworthiness and affects your inbox placement rates.

Avoid risky automations and cold lists

Your reputation takes a hit from sudden volume spikes or messages to unengaged contacts. Clean your list by removing inactive subscribers and invalid addresses.

Tools for ongoing email reputation management

EasyDMARC, MxToolbox, or Google Postmaster Tools help you monitor authentication health. CampaignHQ (https://app.campaignhq.co/signup/) offers automated monitoring to maintain excellent deliverability through its complete reputation management system.
