Just the ideas, not the actual article. This is called a Publicity Pitch. Take those ideas and then pitch them to editors of targeted publications. This can work very well as it saves editors time and puts the outline right into their hands. As a past editor I know how well this works.
Editors love ideas, especially ideas that are completely outlined and correct for their readership.
This means don't send pet article ideas to cooking magazines. Send pet articles ideas to pet publications. But you'd be amazed at what editors see that don't apply to their own publication. Fame comes from planning and persistence. It has its rejections, but if you can learn not to take it personally, it will eventually work.
