Spammers use lots of methods to get bulk email addresses. They depend on their skills and method complexity.

Commonly Used Harvesting Methods

  • Mailing list purchase
  • Website hacking
  • Usage of special software or bots
  • Dictionary attack
  • Tempting with a freebie
  • Mailing list purchase. This is the easiest way to get the addresses. One spammer buys an entire list from the other spammer. Remember that once your email falls into the hands of spammers, your email address will travel from list to list.
  • Website hacking. This method implies hacking the database of a website that is likely to have lots of email addresses, for example, eCommerce. An online store is a good target because hackers may also look for credit card numbers.
  • Usage of special software or bots. These bots are called harvesters. They scrape the website code to find hidden email addresses.
  • Dictionary attack. This is an odd but effective harvesting method. Spammers try different addresses before the @ until they match any valid email address at the domain.
  • Tempting with a freebie. To get any freebie like an e-book, a user should enter an email address, but it doesn't mean a user wants to receive emails from this website. Spammers use these email addresses, as they prove to be valid.

According to the CAN-SPAM Act signed in 2003, email senders are to meet specific requirements. Otherwise, their actions will result in a penalty. Discover the main requirements in this article.
