"ENTJ" is just a short-hand way of describing one of the 16 personality types on a Myer-Briggs personality analysis, and I was just using it as an example. M-B test measures 4 personality major traits, with 2 choices on each trait. For example, Extrovert (E) and Introvert (I).
One isn't just E or I - you are E or I to whatever extent. For example, someone who is just a little "I" may exhibit behavior similiar to someone who is just a little bit "E" in some situations. But someone who is strongly "I" is probably uncomfortable in situations where they need to be very outgoing or at big parties, etc. For example, most sales people probably need to be extroverts. But a few very successful sales people might be introverts - but the type of product or service they sell and HOW they sell ii will probably be very different from most extroverts.
But the 4 measurements together, with 2 choices each, and you have 2 to the fourth power (2 x 2 x 2 x 2), or 16 personality types. What makes each type tick is different, and how each best perceives information is different. For example, accountants and engineers may not be interested in a lot of small talk and pretty brochures with meaningless catch-phrases. They usually want hard data, written/numeric/graphs/detailed samples showing how something works. You may need to persuade them you are an expert in your field, and if you are a "good ol' boy" who likes to wing it, don't expect to close many of these type prospects.
On the other hand, if you have someone who is a "big picture kind of guy/girl," if you use the same approach as for an accountant, the prospect will likely perceive you as cold (they need small talk, "how's the family and weather" sort of stuff) and eyes will glaze over 5 seconds into you explaining your super-duper spreadsheet that proves beyond any doubt that YOUR product is superior to all others.
This is a tangent to the thread, but if you are going to be a professional sales/marketing person, you need to study the topic if you really want to be professional.
How does this relate to mailing list? Well, no one can pull a list for "ENTJ's" or any other personality types. But maybe you can find demographic clues to help. If you find you sell to a lot of engineers, maybe you do well with the former example above. Pull a mailing list of engineers, etc., in certain neighborhoods with income over $X and houses more than Y years old.
Personally, I think it is pretty hard to get a "personality profile" list unless you are selling a pretty specific product or service aimed for those people. If you are a painter or build decks, you're product is pretty general - can you ID the type person who wants what you do?
Good luck!
