Travelers, families, and individuals who want a simple way to send personalized printed postcards worldwide using WhatsApp
About Melon Post
Melon Post is a messaging-based service that allows users to send real printed postcards directly through WhatsApp. Instead of downloading an app or creating an account, users simply chat with the service, upload a photo, write a message, and provide the recipient’s address. The platform then generates a preview of the postcard so users can confirm the design before completing payment. Once approved, Melon Post prints the postcard on premium 350gsm glossy cardstock and mails it worldwide. The service handles the entire process from printing to dispatch, making it easy to send physical postcards in minutes. Payments are securely processed through Stripe, ensuring safe and simple transactions. By combining messaging convenience with traditional mail, Melon Post makes sending personalized postcards fast and accessible.
