What do you know about the blacklist mailers?

Whereas you experience a precipitous decline of email deliveries showings, ask yourself: wasn’t my account marked as blacklisted email? Moreover, today there are at least a hundred ban lists, and you could be sent to one of them. In this article, we shall try to describe the reasons why even successful marketing experts alongside senders whose reputations are far from perfect. We’ll also clear up how to avoid this by using a high-quality free check email

Block-lists types

We may say the email block list is the worst nightmare of any marketing specialist. Play fair if you don’t want to trap into it. Read about the blacklists types to understand the assignment algorithms:

  • corporate — special block-lists and firewalls used by corporate IT departments such as McAfee or Barracuda;
  • private — internal block-lists used by Internet services providers and mail services, such as Gmail or Microsoft;
  • public — block-lists which are in public access and can be verified directly.

Blacklists are divided into 2 groups, taking into account:

  1. sender’s domain;
  2. sender’s IP address.

If your IP address or domain name is in the block list, the mailing won’t be delivered. 

Rule number one is to convince mail providers that you don’t send spam from your IP-address or domain.

If you ignore this rule, you will be quickly identified and sent on “well-earned time off”. 

How do blacklists work

The main tools for the email spam list are spam traps and spam complaints. It is just enough to identify violators with these criteria. A spam trap is a local email address that can be found on a website or forum in order to identify spammers. If you send a mailing list to such an account, you’ll immediately activate the defense mechanisms of the mail providers. 

Spam complaints abundance, as well as information on uncontrolled mailings, can also serve as a background for making a decision to send you to the blacklist. 

The only right choice is to compile the contact database by yourself and regularly verify it for activity and validity.

Is my name on the block-list?

Well, apparently, the indicators have decreased sharply. Let’s check: supposedly there is a blacklisted email. But to begin with, answer yourself honestly a few questions:

  • Do you send mailings to a slab quantity of addresses monthly (500 or more) using an invalid list?
  • Can you say that your account password is easy to guess, you haven’t changed it for a long time, and the chances of being hacked by spammers are high?
  • Have you received failure notifications for emails you didn’t send? Could it be that your account was fabricated?

If you answered yes to at least one of the points, it makes the most sense to make a check. For this purpose, refer to reputable blacklists such as Spamhouse, Spamcop, or SORBS. Each of them is able to provide all the information about whether there were spam complaints addressed to you. 

Tips for removing a domain name from the block-list

Whereas you are still blacklisted, follow the algorithm:

  1. Determine a problem —  check the delivery and open rate indicators, how many people have unsubscribed, and complained about spam. Moreover, each blacklist has an FAQ, where you will find possible reasons for blocking. You should get to know them and make sure to eliminate them.
  2. Send a message to the support — contacting the blacklist technical support can help if you have already found the reasons for the possible blocking. Tell us about the work done and ask them to remove your domain name or IP address from the blacklist.

Keep in mind, that not all ban lists are loyal, and blacklisted email can stay forever. 

Use simple but effective tips to protect your reputation:

  • new users subscription through double opt-in;
  • email verification list — as often as possible;
  • separate IP addresses and domains for different mailings.

The last thing, we recommend you to use a reliable subscriber list check service as an assistant. For example, Proofy.io. Good luck!
