Spam is an unsolicited email sent to a receiver without his consent. It is also known as unsolicited commercial email (UCE), and unsolicited bulk email (UBE). A spam can be sent when the email harvester program finds an email address and puts in their spam list. There’s another way known as dictionary attacks where spammers guess a common email address like info@, contact@, support@, etc.
Here are the ways in which you can control spam:
1) Report spam button: In every email client these days you will find a “Report Spam” button. If you see that an email is spam, select the message and then click on “Report Spam”.
2) Do not leave your email addresses in the web: When you are discussing in forums or in blog comments, instead of leaving your email address you can leave the URL of the contact page of your website.
3) Change the format of email address: Sometimes there may be occasions that you have to leave your email address in a forum or a discussion board. In that case you can type your email address something like: admin AT moreprocess DOT COM. This way email harvester programs will not be able to locate it as an email address.
4) Subscribe only when double opt-in: When you are subscribing for a list, make sure that it is double opt-in and there’s a way to unsubscribe from the list.
5) Email filtering service: Ask your ISP to use a email filtering service.
6) Do not reply to fishy emails: When you see a suspicious email simply delete it or report it as spam.
7) Do not unsubscribe from a list if you haven’t subscribed: You have to make sure that you don’t unsubscribe from a list if you haven’t subscribed to it in the first place. Some spammers use this process to actually find email addresses.
