FAQs

How do I fix a blacklisted IP domain email? ›

What is an email blacklist? The technical name for our subject is a Domain Name System-based Blackhole List, (DNSBL). It lists IP addresses or domain names associated with spam or suspicious content from low-trust senders. A DNSBL is a real-time database that can be updated at any time.

Domains can get blacklisted if there are too many spam complaints—or if the email appears to share the hallmarks of unsolicited promotion. ISPs may block users from accessing blacklisted websites and may prevent them from receiving an email from blacklisted domains or IP addresses.

Adjust your IP address through VPN or Proxies

Utilizing a VPN, proxy server, or Tor Browser allows you to circumvent the IP block and regain access to the website. Nevertheless, it is crucial to employ these methods responsibly and acknowledge the possible risks.

How to remove blacklisted? ›

Removal. If your domain is listed on the Domain Blocklist, you should visit https://check.spamhaus.org. This will take you to our IP and Domain Reputation Checker for more information , and the only place where DBL removals are handled.

Additionally, if the IP address has been used to send out viruses or malware, it may be blacklisted. Other reasons for blacklisting include being associated with phishing attempts, being flagged for suspicious or illegal activity, or being identified as a proxy server used to hide illicit online activities.

Adjust the volume and intervals of sending

You're more likely to end up on an email blacklist if you send too many emails every day at the same time. Keep the number of emails sent per day per mailbox below 100. Ensure that the time gap between emails is not a predetermined period of time, such as exactly 20 seconds.

If you find that your IP or domain is blacklisted, contact each DNSBL service and request that they delete your listing.

One of the major reasons for a sender domain/IP address getting blacklisted is when sent emails hit spam traps. Your emails may hit spam traps when you use purchased mailing lists. Also, mailbox providers use expired email addresses and unused email addresses as spam traps.
