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.
