Monitoring your spam complaints from Comcast subscribers

Posted by David Greiner on December 24, 2007

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.

Thanks for the info David.

On another Comcast topic, I had submitted a support request to you about a huge number of "bounces" from Comcast that were rejected as SPAM by their server. This had nothing to do with anybody clicking on the SPAM button in their webmail client. I know this because when I went to send myself a "preview" at my Comcast email address, it actually bounced and was reported back to me as being blocked for SPAM.

Then a few days later, when I sent the campaign out, a few hundred comcast emails bounced for SPAM and showed up in my bounce list in the reports.

I was told that you guys were aware of the problem and were working on it. Did this get resolved with Comcast?

Hey Mark,

Thanks for following this up. Comcast recently made a number of changes to their filtering processes that saw many legitimate emails being blocked. We approached Comcast about this immediately and the issue was eventually resolved. Since then we have also joined their feedback loop (which I mention above), which has further reduced the chances of any delivery issues like the one we experienced happening again.

I'm curious to know, if Campaign Monitor have caught any of its clients in deliberately sending out spam messages and consequently banned and evicted them?

Thanks Mark, hope you're having a good one too. Dan, yes, we've unfortunately had to close many accounts over the years when a customer isn't explicitly sticking to our anti-spam policies.

I am an E.D. of a small nonprofit that advocates for children and adults with developmental disabilities. We produce a monthly newsletter on special education issues. The folks who get this e-mail have specifically signed up to obtain this information.

Yesterday, I sent the newsletter out and ALL of the comcast.net subscribers were returned as not deliverable. Separately, a comcast.net subscriber e-mailed me regarding an unrelated issue and when I responded it was ALSO returned as not deliverable.

I think my e-mail address must be on some sort of blacklist for SPAM although it is not. Mark above referenced you are working on separating the legitimate communicator from the SPAM; so, what should I do to have this addressed in respect to our legitimate communication?

Thanks,
Darla

Darla, I just double checked and noticed you're not sending your emails through our software, so my best advice would be to check the explanation in the bounces you received from Comcast (which will usually include a reason for the bounce and a link to find out more).

Alternatively, you might consider using a service like ours who can resolve these issues on your behalf.
