Welcome to

the Sweetheart Society Mail Club

The Sweetheart Society Mail Club is a monthly subscription created for romantics, creatives, and anyone who still loves receiving something real in the mail. Each month, you’ll receive a 5 × 7 art print, a letter from me, a quote of the month, and a small surprise sticker. Every piece is designed to feel thoughtful, personal, and worth holding onto.

This club is about slowing down and creating a community of people who genuinely love receiving something tangible and thoughtfully made. In a world that moves so quickly and lives mostly on screens, this club exists to bring back the magic of love letters, handwritten notes, and the feeling of being personally thought of. Every envelope is a small reminder that connection can still feel intimate, intentional, and real.

If that sounds like you, I’d love for you to be part of it!
