If you’re just getting started with copywriting and/or content marketing, the “Boron Letters” by Gary Halbert is one of the best resources you can get. You can read it for free – Gary Halbert’s son published the pages on his website. I linked them up this page here.
If you’re like me and like to have a hardcover book, you can also get it on Amazon here. Please note, I will get a small commission if buy the book from Amazon via the link above.
NOTE: If you’re only interested in copywriting and content marketing, skip the first four chapters (they’re about health).
