Email is a great way to communicate.
But you may receive mail from a company or charity that isn't familiar to you. Like telemarketing calls, an email may be legitimate or it could be a scam. If you're not interested, delete the message. Reputable sites should make it easy for you to subscribe or unsubscribe to email lists. To reduce the amount of unsolicited email you receive in your main inbox, consider using two email addresses, one when you are communicating with friends and colleagues, the other when you are dealing with companies or organizations.
