usps –––– Send something real
USPS has been delivering mail for years. The big boys (Fedex and UPS) came in and dominated the shipping business. The post office have bad customer service, slow delivery time, and there's always a line. But, one thing USPS can own is mails; handwritten letters wrapped with a physical envelope and sealed with a human tongue. That's personal. In today's age, no one sends personal things anymore. Apps, templates, e-cards are designed by someone else, not you. Sometimes slow is good. It's more meaningful.
