How about this, I activated a trigger campaign but I forgot to add that if they converted or request a trial only, at a particular time frame, then send them a welcome letter and login instructions. So one lead from Germany got the 2 letters above and sent an angry email saying that he declined and wasn't interested in receiving our publications a few months ago. There were a few others who received the unintended email but only one complained. Ugh and our data associate wanted me to explain why this happened.
