Learn the principles of the work of spam filters
As any web-based tool, spam filters are recognized as a set of different algorithms that assess incoming emails and define their containment of spam through the prism of a numerical score. The higher this score is, the more probability is that the email will be marked as spam and go directly to the spam folder.
As a result of continuous development, nowadays spam filters are much more precise, attentive, and strict when they face every incoming message. The spam filters analyze not every detail of email content, but also, explore the sender`s behavior and check every word of the message.
Today email marketing systems present a lot of gateways. They denote network nodes that are used by spammers to harm vulnerable data worming into business correspondence. In order to avoid it, the gateway is secured by a particular spam filter, created to make it impossible to open the spam emails by recipients.
Let’s find out together the most popular spam filters:
- Content Filter. This type of filter is one of the simplest and popular functions for spam filtering. It focuses on the scanning of incoming messages, evaluating their quality, and finding spammy words. The main disadvantage of this spam filter is that sometimes it can block even valuable or safe emails because of the minimal containment of spam trigger words. It is important to note that such a situation occurs because the sender or owner of emails doesn’t care enough about both Sender Score and email deliverability.
- Head Filter. The main function of this filter is to identify from whom the message has been sent. Generally, when we get an email, we pay attention to the name of the sender and time. However, there are a lot of other important elements which spam head filters take into account. Firstly, it is a message ID that is recognized as an identifier for a particular message and used to verify falsified emails. Secondly, the head filter takes into account an address of a sender to check whether this sender has a good domain reputation, or he is suspicious or even blacklisted. Thirdly, this filter also allows you to explore the sender`s DNS records, DKIM, SPF policy.
Email checker and language filters
As a result of globalization and digital progress, email correspondence has gained its importance and international validity, therefore language filters have become also essential in the launching of email campaigns. A lot of spam attackers include location characteristics to make sure that a recipient will open and click on their links.
The main function of language filters is to scan the language of a message and spam if emails are written in a foreign language and seem suspicious and dangerous. A spectrum of functions of this filter time is limited, so you are able to customize it by yourself in the configurations of your email platform in order to improve the safety of data.
