Proactive greeting
When to use: Send after the visitor spends a little time on a key page without reaching out.
Message
Hi visitor first name, thanks for stopping by business name. I noticed you have been reading about page topic -- would it help if I walked you through how we handle it or answered a quick question?
Variation
Hey there, I am agent name and I work here at business name. If anything on the page topic page is unclear, just tell me what you are trying to sort out and I will point you the right way.
Why it works
A small business wins trust by feeling personal, so this names the page the visitor is on, offers real help instead of a plain hello, and makes clear a person is replying. That combination earns the first response far more often than a generic greeting ever will.
