I received a great question yesterday asking if a pitch in a click-through newsletter format was a good idea. My first reaction is no. A pitch should be personalized and any signal to an editor that you have sent this to every media contact on your list--no matter how punchy or beautifully designed--will send them reaching for the delete button.
That said, a newsletter-style blast to your media contacts in between your pitch time, like this example below, is a great way to stay fresh in the editor's mind and to, perhaps, showcase a collection standout. In much the same way that an oversized postcard keeps your brand presence on the editor's desk, a pretty picture attached to a timely idea does the same trick, minus the postage!
