What Is A Spam Filter And How Does It Work In Gmail

A spam filter is a software solution that processes incoming emails to detect spam messages and prevent them from reaching the recipient’s inbox. Spam Filter – Gmail also works on the same principle. The spam filter checks each incoming email to determine if it is spam. If it is detected as spam, it will be sent to a separate section labeled ‘Spam’ instead of the primary inbox.

What Do Spam Filters Look For?

Let us now see what spam filtering solutions look for with the Gmail spam filter as an example. The service works with multiple complex algorithms to identify spam messages and filter them. Here are the factors Gmail spam filter look for in the detection of spam messages.

  • At the outset, it checks if the email address of the incoming email is blacklisted. If it is, then the job is easy. It can directly filter it as spam and send it to the spam folder as it has been known to be a spam address before.
  • In case of incoming emails from addresses that have not been blacklisted already, the spam filter – Gmail looks in a huge database it maintains to get clues of the sender.
  • The spam filter can also check for specific text strings characteristic of spam emails in the content or header, such as “How to make quick money” or “Win a quick $50 bucks,” and other such strings that are consistently being marked by spam.
  • Another factor Gmail spam filter looks for is lousy grammar and spelling errors. They are characteristic of spammers compared to serious emails from standard organizations.

However, spammers are also innovative. They know how Gmail algorithms work and try to override the above spam filtering techniques by applying more tricks such as using code-words instead of the words the filter looks for in a message. Hence it has become necessary for Gmail also to resort to much higher options. Now, Gmail spam filter service works with AI support. Its Machine Learning framework TensorFlow helps in filtering millions more spam messages every day than before.
