Spam Filtering and Email Junk 101
2009
I’m always getting bombarded with people asking about Spam Filtering and what ‘settings’ have been changed due to the fact that their many ‘homegrown’ mailouts are going into peoples spam filters, so I’m trying this post to demystify and explain how the system all works and how you can do your bit to make sure your emails go into peoples inboxes, not spam/junk folder.
First, you need to understand that most spam filters work using an extremely complex mathematical formula called Bayesian Filtering.
