Spam emails are typically sent out in millions if not billions of copies. They are designed to sell junk products of various kinds, such as fake drugs, watches or clothes. They may also be scams claiming that you have won the a fake lottery or that you inherited a lot of money from a rich relative who never existed.
Newsletters and marketing emails
We are all different and each has a different definition of what spam is. We noticed that for many, spam is any email that you do not want. Including newsletters or offers from a company that you have a relation with. Deals that one (maybe reluctantly) accepted to receive. Often you can unsubscribe from these emails, but you might find it too complicated. It may also be advertisings that you never asked to receive, but that may not be pure spam in the traditional sense. This is less prioritized emails. We call it newsletters and marketing emails. So even if you think they are spam, for SpamDrain to work well, please report these types of messages as Newsletters.
