I need a temporary suppression list (not a permanent "Do Not Mail") function. I've been doing this for years with Aweber and can't believe you don't have this ability. For example, let's say I do a mailing to my list and offer a 10% discount and get a certain number of buyers. A few days later, I want to do another mailing and offer a better deal (like a 20% discount). To avoid problems, I don't want to send emails to the people who already purchased the 10% off deal. I don't want to permanently put the customers on the Do Not Mail list, I just want to suppress certain email addresses on individual mailings. Is there any easy way to do this?
