I'm sending YH. Over the past week or so I have seen a jump in clicks with no increase in conversions. The increase is all coming from the same /27. The open IP of all the users that these clicks are coming from is different, everything is unique IPs for the opens. I looked up the /27 in arin and it belongs to a internet security company. I've been mailing this data for a long time and this just happened out of the blue. Nothing has changed, just the jump in theses clicks. One other thing. Offers that normally get higher clicks are getting more of these clicks. Offers that normally get lower clicks are getting less of these clicks. What would you do...remove them from the list?
