Yeah just go to Google and type credit one CEO and then type his name and whats email in search bar. As for email format I didn't use any format. I just was honest. I opened the letter with a basic greeting and asked for a few moments of their time, I was very respectful. Then I went on to describe what happened and why I defaulted and how grateful I would be for the tradeline to be deleted. Make sure you include account number and your name. That's honestly it there's no strategy or necessary wording. As long as you make it clear you want tradeline removal and make sure they understand what troubles you endured that caused you to default. People seem to be having success so good luck and don't over think it.
