Sales Letters

I write direct-response sales letters for offers that need a personal, persuasive voice. Some offers need one person speaking to one person at length, and a letter can carry the full case for a considered purchase. I work from your offer, buyer profile, objections and the founder's own stories, then use AI to structure argument options and check claims against the proof library. You get a finished letter with headline options and a proof appendix, so every promise on the page has support behind it.
