When talking to a specific customer, in my experience, it's better to not use phrases like "we know that many companies JUST LIKE YOU do X and Y". That seems unpersonal and frankly, a bit like a smartass.

Better:

- Reply directly to their concerns and questions without any fluff.

- Ask the customer about their problems, wants, and needs. Maximize your understanding of their problem space.

- And: Throw out the jargon. [0] It sucks.
