Keep customers coming back to your store with direct mail. It’s simple, effective, and environmentally friendly too. Mailfold syncs with your Etsy store and allows you to send direct mail to your customers. We’ll have your campaign mailboxes within 2-4 days of printing. We’ve also partnered with Eden Reforestation Projects to plant 1 tree for every 10 postcards sent. So we plant way more trees than we use. Mailfold is only available within the U.S. for sending and receiving. The service is in English and accepts U.S. based payment methods Visa, Mastercard, American Express, Discover, Diners Club, and JCB.
