As I’ve mentioned before, your sending reputation and the relevance of your email are some of the most important factors that can determine if your email arrives in the inbox or the junk folder. In order to evaluate your sending reputation, more and more ISP’s are using their “Mark as Spam” button. It’s pretty simple, if you only occasionally get a spam complaint made against you and you don’t send to that address again, you should be OK. Get lots of complaints and keep sending to those addresses and you’re in trouble.
Many of the popular ISP’s out there share these complaints with Campaign Monitor so we can monitor our customers and also keep your lists clean of those who clearly don’t want to hear from you any more. To date we’re reporting on such complaints for Hotmail/MSN, AOL, United Online, Roadrunner and USA.net.
We have now extended our spam reporting feature to include Comcast, the largest cable internet provider in the US. This means that any time a Comcast subscriber marks your email as spam, we’ll remove them from your list and also provide a detailed report saying who did this and when. This integration means your list will stay clean automatically and you can gather indirect feedback from your customers about the relevance of what you’re sending them.
