Entity vs Not mentioning Entity

[George P.]

In your experience, does it add credibility when you add the name of the company after your name?
Some say that sellers don't like to deal with corporations, others argue that sellers will have more confidence that you close if they deal with the company?

Personally, I prefer a personal approach in my direct mail, so adding a company name (which I did not set up yet) might kill this personal touch.

Any opinions?
