I am launching a premium subscription product that sends personalized physical letters by mail each month. I’m looking for an experienced Shopify automation specialist to set up a clean, reliable system from purchase → personalization → automated mailing. This is a lean build for a modern DTC brand. I value clean architecture and simplicity over over-engineering.
