I subscribe to the Worldwide Freelance Writer newsletter.
While this website caters mostly to the novice writer, I still like having paying market leads delivered to my inbox for free. There’s always a few global markets that I haven’t heard of. Here’s a sample newsletter.
I did buy their list of 50 Travel Writing Markets for $5.95. While some of the contacts are out of date or the links don’t work, the editor does send an occasional refresh list. At $5.95 you’re not really losing any money if you find even one good lead that works for you. Right?
