Gmail uses innovative technology to block spam

Gmail has one of the best Spam block software that prevents many incoming spam mails to your inbox. Spammers are finding it harder to send emails and evade the innovative spam block technology used by Gmail.

One of the main reasons many prefer Gmail because of Google’s spam protection, which does a great job in separating the good ones from the bad. The video shows some of the ways Google uses to block spam.

In Gmail, there is a button called “Report Spam” which is a great community feature as seen below. For example when the spam message somehow avoids Google spam protection tools, and when you click this message as “Report Spam”, the Gmail will recognize this type of message as Spam the next time and not only block it at your e-mail account, it will block that message with everyone else’s email accounts also. Thus Gmail’s spam block technology learns with every click we report the spam messages.

Every day, new spam techniques are developed to avoid Gmail and other e-mails such as Hotmail, Yahoo Mail etc. So when Google learns these new techniques it modifies it spam block algorithms also to fight these new spam techniques.

Another technique Spammers use is images, which is hard for Gmail to block, but with OCR (Optical Character Recognition), it is able to read what the image content says and blocks the messages.

Gmail uses or supports multiple authentication system to verify the sender and help identify whether it is real or forged messages. They use Sender Policy Framework (SPF), DomainKeys (which domain the message originates from) and KIM (DomainKeys Identified Mail). This will make sure the sender is authentic and originates from the sender itself and not through a third party.

So, the more sophisticated the Spammers get, the Gmail gets even tougher and is ahead of them by many steps. Look at the number of spam messages Gmail blocks with increasing year, it eliminates almost all of them.

I get about 100 spam messages every day, Gmail blocks almost 99 percent of them, the one or two I get, I report it, so it will be avoided in the future. If you are not using Gmail you should use it and avoid bogus messages that may cause problems to your computer and unsolicited messages.
