It appears that the people at E-ChannelNews.com do not want you to contact them. You cannot unsubscribe from their unwanted email (the provided mechanism doesn’t work.) There is no phone number to contact them with and any attempt to email them bounces back.
It is this author’s expert opinion that they are spammers – and I am going to report them. If you are having trouble getting off their mailing list I suggest you do the same.
