Email Spamming

How to Identify Spam Emails?

It is good to have knowledge about spam detection technique before to answer any email. When users have knowledge about spam mails, they can prevent them from being a victim of email spamming. I have discussed some useful techniques to identify the spam mails that are as under.
  • Spam emails always come from unknown senders having odd email address. Such emails ask to reset password, and login credentials etc. Therefore, it is wise to check the sender information of suspicious message.
  • Spam emails may contain grammar mistakes and oddly worded sentences.
  • Spam emails may contain punctuation and capitalization errors.
  • Any lottery or contest winning mails should be avoided especially, when a user did not apply to any contest or lottery. Such mails ask for password or login details to complete the lottery procedure to steal user personal information.
  • Do not download any mail attachment if it is from an unknown source. Such attachments often contain a virus or malware that might infect the user system.

    How to stop getting spam emails?

    After getting knowledge about email spamming, there are some precautions that users should take while dealing with emails.
    • Phishers grab bulk email addresses of people and use them to post free stuff offers like TV, mobile phone or any electronic device.
    • Do not share primary email address anywhere as it can put the user at risk.
    • User does not need to click “Unsubscribe” link as spammers know about the valid email address, and it will help to generate more spam. Therefore, it is best to delete spam mails.
    • Avoid using the same username and emailing address for mail account. Spammers can easily identify the email address of a user by username.
    • If the user receives any spam message in his/her inbox, then user should click on “Report a Spam” button so the next time such as mail sender will be counted as spam mail.
    • Apart from these, there are many companies like SpamExperts offering different services and tools that can help you to filter such emails and provides better security against such emails.

    Spam in the spotlight in 2014:

    In January 2014, the world witnessed few spamming activities rather than lottery winning, corporate job offering, dating sites etc.
    • English-Russian language mass mailing that offered video surveillance system.
    • Nigerian fraudsters announced false death of Nelson Mandela and Ariel Sharon (Israel Prime Minister).
    • Holiday spam mail related to meal trip, flower offering, romantic tip etc to steal money from people.

    Conclusion:

    Email spamming is a common technique but can make heavy damage to user’s privacy. The above precautions are necessary to avert such a perilous situation. Currently, many anti-spam tools are available to fight against spam mails.
