Follow-Up: Polite Close-the-Loop

Hi {{first_name}},

I do not want to keep following up if this is no longer relevant.

If timing changes later, I am happy to reconnect.

To make this easy, here are two options:
1) Reply "interested" and I will send a concise next-step plan.
2) Reply "later" and I will follow up at a better time.

To make this easy, I can send a one-page summary covering current status, dependencies, and the most efficient next step.

If you reply "yes", I will send it right away; if timing changed, reply with a better window and I will follow it.
