=== Follow-up 1: offer a walk-through ===
When: About 3 working days after sending
Subject: [Project name] proposal: any questions?

Hi [First name],

Checking that the proposal for [project name] arrived safely. If it would help, I can walk you through it in a 20-minute call: [booking link].

Best,
[Your name]

=== Follow-up 2: one useful detail ===
When: About 7 working days after sending
Subject: [Project name]: what the first two weeks look like

Hi [First name],

One thing clients often ask is what happens right after they say yes. For [project name], the first two weeks would be [first step, for example a site visit and measured survey], then [second step].

Is there anything in the proposal you would like changed or explained?

Best,
[Your name]

=== Follow-up 3: close the loop ===
When: About 14 working days after sending
Subject: [Project name]: keep the proposal open?

Hi [First name],

I have not heard back on the [project name] proposal, which is fine. Should I keep it open, or close the file for now?

Either answer helps us plan. If the timing has moved, tell me when to check back.

Best,
[Your name]
