Let's say i'm building software for email marketing , is there any way to figure out wether the end receiver of an email marked it as spam ?

  • No. It's a one-way ticket out of your server. You may never know if they receive it, if it's marked spam, etc. – random_user_name May 25 '12 at 14:30

    I hope not, not because I care about your reaction, but because it would imply that spam can confirm live email addresses without having to receive a response. – David Thomas May 25 '12 at 14:30

    Just build it so it sends emails that are already marked as spam. Then you can be sure that it is marked as spam at the receiver's end. :) – kitti May 25 '12 at 14:32
  • Unless you control the remote host or remote email client, no. – Todd A. Jacobs May 25 '12 at 14:32

Not really. The only thing I have in mind is to put an image into the mail, reffering a specific ID to check if the user views the mail. After a while you could then say, the user has marked it as spam or doesn't read it, when nothing comes through the image.

But almost every mail-client disables image-loading for the first time and there are other users who don't view HTML-mails, so they won't load the image.

I hope I have helped you a little
