Hi [First Name],
Wanted to check in on the proposal I sent [day]. Rather than ask "any thoughts?" — a more useful question:
Is there a section that needs a closer look? Usually it's either [common question 1 — e.g., "how the rollout phase works"] or [common question 2 — e.g., "the pricing tiers"]. Happy to walk through either in 15 minutes.
If it's making the rounds internally, I can also send a one-page summary that's easier to forward.
What does your timeline look like for a decision?
Best, [Your Name]
