Postmarkd

Postmarkd is a mobile + web app that helps people write meaningful love letters and actually send them as physical mail on a schedule. You write in a clean editor, choose stationery style, add photos, and pick a delivery date (anniversary, rough week, long-distance milestones). The app prints and mails the letter via a fulfillment partner, so it feels real—postmark, envelope, and all—without you needing stamps, printers, or a trip to the post office. Optional AI assists with structure, tone, and prompts (not full “cringe bot poems”), and it can suggest edits to make the message sound like you. The core value isn’t “more words,” it’s follow-through: turning intent into a delivered keepsake. Monetization is per-letter plus a light subscription for scheduled series and premium stationery.
