Basically, there are two types of recruiters:

1. "Hi there. After reviewing your profile, I believe you have what it takes to be a <role> in our company."

2. "Hi there. After reviewing your profile, I'm convinced that you have what we need as a <role>."

Interestingly, the former tends to ignore your response if you rejected their advance, while the latter tends to follow up with a "just reach me out if you changed your mind", or even a simple "I understand, thank you for your time".
