Show HN: Purpose Reminders – One simple, positive act emailed monthly to all

Hi HN,

I built Purpose Reminders (https://purposereminders.com). Our first monthly action – "Leave a positive review for a local business" – goes out June 1st (very soon!).

The core idea: What if thousands of us did the same small, positive act each month? You get one email, choose to act or skip (no pressure), and then see the collective, anonymous impact.

It's 100% free, built with Next.js/Supabase/Resend. My attempt at a simple way to foster some collective goodwill.

What do you think of the concept?
