One of the worst nightmares for any email marketers is getting their email blacklisted. As it can negatively affect your ability to reach your subscriber’s inbox. With the advancement in technology, the occurrence of fraud has increased, and the ISP (Internet Service Providers) has employed different means to protect their users from spam through spam traps, spam filters, and email blacklists. With all these tools, high engagement and deliverability rates is a tough job for all the professionals. Avoiding the red hand of the email blacklists and the spam filters is not an impossible task if you regularly keep an email blacklist check and update yourself if your email is blacklisted.
Let us first understand what the email blacklist are and how they work.
What is Email blacklist?
They are the list of IP addresses and Domains that are suspected of sending spam emails. It is a real-time database that helps you decide which emails should be considered as spam and avoided. The email blacklist tries to protect its users from spam emails and decrease the deliverability of unwanted emails to the users.
There are two types of blacklists:
- IP address blacklisted: It is the collection of the IP addresses that are suspected of sending spam emails or other types of abusive emails.
- Domain blacklisted: It is the list of all the Domains that are found sending spams and misleading the users.
Email blacklists are based on a number of identification algorithms. When your email address is blacklisted, your emails will not land on the primary inbox.
How does an Email blacklist work?
When you (Sender) send an email, it is received by the ISP( Internet Service Provider) (Receiver) who has the upper hand to decide that whether your email seems legitimate or not. The ISP confirms that your IP address is not in any pre-existing blacklist. Once the spam filter shows the green signal, it then goes to the subscriber’s inbox.
Email Blacklist is one of the tools that the ISP uses to ensure that the email address is legitimate. All the criteria for blacklisting the email is based upon the policies of the ISP. Hence, it is necessary that you draft the email as per the guidelines given by the Internet Service Providers.
