Email-Based Project Start Tracker

My “pet” project is almost ready to go, but I still need a rock-solid way to capture one critical detail: the exact day work officially begins. That single date has to arrive in my inbox (and any stakeholder’s inbox) automatically, with no extra dashboards to check. Here’s what I’m after: • A lightweight solution—script, automation, or any clever method you recommend—that records the project’s start date and fires off a confirmation email right away. • If the date ever changes, the system should resend an updated notice, still via email only. • Clear, step-by-step hand-over notes so I can tweak recipients or triggers myself later. • A short walk-through call scheduled over email once everything is running. I don’t need payment schedules, Gantt charts, or full project management suites—just that one milestone delivered reliably by email. When you respond, focus on your experience building similar notification or scheduling tools and keeping them painless for non-technical users. If you’ve streamlined single-metric trackers before, tell me about it; that’s the kind of expertise I’m looking for. Let’s keep it simple, fast, and email-centric so I can hit the ground running the moment the start date is set.
