Today we will know about email blacklist. Have you ever emailed someone and not received a reply? You may be wondering why your email hasn’t been answered. The recipient may have been busy or not seen your email, but it is also possible that the recipient’s email server has blocked your email. One way an email server can block emails is using a blacklist.
What is an Email Blacklist?
The Email Blacklist is a comprehensive database of public domain and IP addresses identified as suspicious for sending spam emails over the Internet. It is also well known as DNSBL (Domain Name System-based Blackhole List) or RBL Real-Time Blackhole List. Organizations such as Email Service Providers (ESP), Internet Service Providers (ISP), and Anti-Spam Agencies (ASA) use this list to identify, monitor, and block any spam email entering their networks.
Am I blacklisted? What are the symptoms?
There are many signs to alert you to the status of your IP. When you are blacklisted, you cannot send emails properly to recipient mailboxes. Now, this does not mean that you will be blacklisted from every mail server in the world. If you are blacklisted with one DNSBL service, there are hundreds of others who may not blacklist you. Some key symptoms:
- The number of lost emails increased.
- You experience deteriorating delivery rates.
- You find a high number of bounce rates in emails.
These do not guarantee you will be blacklisted but are some warning signs. If you ticked a few boxes for delivery issues, you can now check to ensure the domain or IP address is blacklisted.
Checking your IP address and domain against an email blacklist directory
There are many different email blacklist services on the Internet. It is not practical to check every one of them, but some applications maintain a list of live RBL (realtime blackhole list) directories to save you time. They provide a page dedicated to that RBL service and also offer a service to get your domain or IP address removed from the list.
Here are some popular RBL applications:
- MXToolBox: It checks domain blacklisting across multiple RBL lists. It provides detailed information and advice about the current status of your domain.
- MultiRBL: This is a free DNSBL lookup site that can check domain blacklisting by scanning 100+ DNSBL lists. It details the steps to remove your domain from the blacklist.
Malicious sites can be blacklisted by Google Safe Browsing, which will alert visitors to potentially unsafe pages. Dropmysite includes a feature that sends you warnings if your site is listed in this blacklist-monitoring program.
So take corrective action immediately before it’s too late! Oudel Inc. Dropmysite is offered as an add-on cPanel plugin so you can back up your data and monitor your websites. These services may help you proactively monitor your IP address to ensure speedy delivery of all your email
Blacklists are an important tool for email deliverability. They help protect email users from spam and phishing emails & improve the deliverability of your valid email campaigns.
If you are not familiar with blacklists or are unsure whether your IP address is on one, we encourage you to use the blacklist-check tool. Use this information to clean up your email practices and improve the likelihood that it will be delivered to your inbox.
