Senuke definitely still works.. but you have to use it properly. Think of it like excel spreadsheet. The first time you open it up and start using it, you do not know all the extras and expansive ways to use it. Actually learn the software and what it will provide to your campaign. I personally use it to hit my interior pages of my sites, works great for long tail keywords, not so much on the short tail (unless they are stupid easy). And do not stick to the wizard or ready to go templates. Think about how many people are using these exact same templates and the footprint they are leaving behind. Make your own campaign, use your own content and not that spun gibberish from the auto gen, put a real press release in there with only a small spin to it, and guys.. really change up where in content your anchor is. If its in the same sentence on every page across each blast, even I can figure it out, so you better imagine that google can to.
