Hi [First Name],
Thanks for the time today. Two things stood out from the demo:
You mentioned [pain point] is costing the team [impact]. The [feature] workflow we walked through addresses exactly that — [one-line recap of how].
You asked about [question they raised]. Short answer: [concise answer or "I've attached the details"].
Next step, as discussed: [agreed next step] by [date]. I'll send over [promised item] before then.
Anything I missed that would help [decision maker / the team] evaluate this?
Best, [Your Name]
