What this Founder actually cares about

A founder in Legal is protecting runway, focus, and the company's early reputation. They context-switch constantly and reply to emails that reduce uncertainty. They can smell a template that was also sent to 400 peers. The hook that earns a look is a problem they personally still own because the team is small. The ask should stay at this size: a yes/no on timing, or a 15-minute working chat. Delete trigger: Calling them a 'decision maker' or pitching like they're a Fortune 500 process. If your note would embarrass them in a team channel, rewrite it.

Given this is after an invoice, ask if it's in the next run, or what document is missing.

Hope the rest of your week is quieter than the start.

Questions people ask before they hit send

Name the situation and the business object, not your excitement. Something like "Grateful for today's [meeting/intro/help]" outperforms "Just checking in" because a founder can decide from the preview text whether it's worth opening. Keep it under 50 characters when you can.
