What if I don get an important e-mail from a potential new client who is not in my whitelist?
You will always receive all your messages. This is another benefit of the whitelist method. You will always receive all your messages. Your whitelist is used to determine if an incoming e-mail should be placed in your Inbox or your spam folder. So that important e-mail message from a real person who wants to do business with you but is not in your whitelist yet will be delivered in your spam folder. Most people check their spam folder a couple of times a day. So, at lunch time you see the message that was delivered in the morning. and you have plenty of time to respond.
