A letter from me

Hi, I’m Mady.Oakville mom, professional snack distributor, and someone who still gets weirdly excited when there’s real mail in the mailbox that isn’t a bill, a flyer, or a credit card trying to “change my life.”The good kind of mail.Life moves fast — kids, schedules, groceries, phones constantly buzzing with notifications we didn’t even ask for. Most things we receive now live on screens and disappear a few seconds later.So I started wondering… what if once a month something different showed up instead?A real letter.
Something you can hold.
A tiny moment of calm before someone inevitably yells, “Mom, where are my shoes?”
That’s how the Cozy Post Society started.Right now this is just a small project getting off the ground, and the first envelopes are currently being designed and will launch once the founding waitlist fills. Once the first group is ready, I’ll send an email inviting people to reserve Letter No.1 - The Beginning.My hope is that these letters create a small shared moment — different homes, different lives, all opening the same envelope and slowing down for a minute.And if the idea of a cozy letter waiting in your mailbox makes you smile even a little, I’d love to have you on the list.— Mady ✉️
