Anyone use incogni.com or deleteme.com?

Agree.  Gmail spam is annoying.  I haven't figured out how to unsubscribe.  Many messages do not have an easy unsubscribe button.  It appears Google does not want me to know how to do so easily.  "Report spam" does not do the job.

I agree that it's annoying.  One thing that you can do is to divert spam to the delete folder rather than have it land in your spam folder.  Then it will be deleted with your other deleted emails, and not require a separate effort.  However, I don't even want it spamming up my deleted mail, and prefer to review it before deleting in case something mistakenly slipped by.  So, I'm stuck with it, just going with the inevitable flow.
