Subject: Next steps for [project name]

Hi [client name],

I’m checking in on the proposal for [project name] sent on [date]. Have you had a chance to review the scope and proposed schedule?

I’m happy to clarify the deliverables, pricing or assumptions. If a different approach would be more useful, please let me know what has changed.

Would [a short call / feedback by a date / written confirmation] be a useful next step?

Best,
[your name]
