What is the bulk mail?

Bulk mails as can be called spam too. These are mails sent to your mailbox without your concern and permission. These contain information which you never intended or apllied to recieve. Many sites and companies use email ids collecting to promote their products. You would have seen in some mails, product selling like they ask you to buy medical pills or viagra, these are from sites where you never visited.Sometimes you post your email to a friend or while chatting, on forums, these sites then use email ids from such places and send their product info to those email ids. All email providers are aware of such spamming so they don not count bulk mails toward your mailbox storgae space. However you can get an email from a trusted site into bulk mail too if your email provider has no information about that website. To get it into your inbox mark it as not spam or add the id to your mailing addresses and you'll recieve the next mail from that id into your inbox. So if you wanna stay away from spam then don't post yur email id everywhere on internet as it can be misused for spamming.
