PostPilot

PostPilot is a direct mail automation platform built specifically for ecommerce brands that want to reach customers physically. You can create, launch, and track postcard or catalog campaigns directly from your dashboard, treating direct mail with the same speed and data-driven precision as your email marketing. By connecting your store, you can trigger physical mail based on real-time customer behavior like abandoned carts or second-purchase reminders.

You can design your own mailers using a simple drag-and-drop editor or lean on their professional design services to handle the creative work for you. The platform eliminates the traditional headaches of direct mail like minimum order quantities and long lead times. It helps you cut through the digital noise of crowded inboxes by landing a tangible, personalized message directly in your customers' mailboxes to drive higher lifetime value.
