What are Email Blacklists?

Email blacklists (also known as RBLs or DNSBLs) are databases of IP addresses and domains that have been identified as sources of spam or malicious email. Email providers use these lists to filter incoming mail and protect their users.

Being listed on a blacklist can severely damage your email deliverability, causing your messages to be blocked or sent to spam folders. Regular monitoring is essential to maintain a good sender reputation.

How to Get Removed from Blacklists

1. Identify the Issue

Determine why you were blacklisted. Check for compromised accounts, spam complaints, or sending to invalid addresses.

2. Fix the Problem

Resolve the underlying issue that caused the listing. Clean your email list, secure your systems, and implement best practices.

3. Request Removal

Visit the blacklist's website and submit a delisting request. Most lists have an automated process once issues are fixed.

How to Avoid Blacklisting

  • Only send to opted-in, verified email addresses
  • Implement double opt-in for new subscribers
  • Monitor bounce rates and remove invalid addresses
  • Set up proper SPF, DKIM, and DMARC records
  • Warm up new IP addresses and domains gradually
  • Make unsubscribe easy and honor requests immediately
  • Avoid spam trigger words and deceptive subject lines
  • Regularly check your blacklist status
