The first email rarely gets the yes. It gets noticed. The follow-up is what actually gets read and answered, so the sequence matters more than any single email.
When someone actually responds, hesitation kills momentum. Having the right answer ready the moment they reply keeps the conversation moving instead of going cold again.
"Not interested," "how much," "we already have someone," they're not rejections, they're the five things people say before they say yes. Answer them the same way every time, and you stop losing deals to silence.
