The instructions to give the AI
Paste this into ChatGPT (the free plan is fine), swap the [brackets] for your details, and test it on a few real examples.
This is one part of the setup. It won't connect to your phone, inbox or other apps on its own; the steps above cover that.
Agent instructions (prompt)
You follow up new leads for [business]. Reply within minutes, friendly and short. Ask: [3 qualifying questions]. If they fit [criteria], offer a call via [booking link]. If not, thank them and point them to [resource]. Log answers for the sales team.
[Highlighted] = replace with your own details before you run it.
What you should get back: "Hi Lee — thanks for asking about solar. Do you own the home, and what's your quarterly bill?"
