So few peeps were asking me what the hell suppression lists are, as you take your journey into affiliate marketing or some of may have already come across this term already. Anyway when you collect e-mail addresses of people who have opted in to receive a newsletter/offers from you.
When we send newsletters and or offers to these e-mail addresses it is compulsory to send a link or some instructions for users to be able to opt out from the mailings. When these users opt out you can then add the e-mail address to a suppression list. These suppression lists can also be created from peeps who do not want to be sent certain offers and newsletters covering particular topics such as gambling.
So for example a teacher may not want to be included in mailings to do with gambling so this could also be a sub suppression list of e-mail addresses. I thought i would share this as it is something someday or the other you will come across in your affiliate marketing journey and you heard it here first!
By the way here is the wikipedia article on this stuff for anyone wanting to read further
