Black list

Blacklist is a list of IP addresses that have been blocked by an email provider or spam filter for phishing and spam.

If your IP address is on the blacklist, then the mailing will not be sent or will have to go through additional spam filters. According to Forrester Research, spam messages make up 67% of all email traffic. That is why ISPs should protect their clients from these types of messages. This can be achieved by filtering messages and checking the legality of the mail delivery. Using blacklists, the ISPs can reduce the number of spam messages in their networks.

Email providers use blacklists that created based on publicly available information and internal ISP data. The blacklists use different spam identification algorithms, for example, "unwanted email." If you send "unwanted email" and it collects a lot of spam complaints, then there is a high probability that you will get onto the blacklist.

ISPs use the most reputable blacklists – Spamhouse, Spamcop, and SORBS – to check the sending server IP addresses by requesting problem senders.

If your mailing has a high percentage of subscribers who mark your letter as spam, then the LIKE.TG server will get onto the blacklist. That is why, when using our server, you should follow the rules of our Antispam Policy.
