Trinity Shiroma, a 25-year-old artist in Orlando, Florida, earned nearly $18,300 (£14,500) in profit from the May edition of her subscription snail mail service, CNBC wrote.
Shiroma runs The Architecture Club, where more than 2,700 subscribers pay $8.88 (£7) a month for a hand-painted postcard of a landmark building, a letter about its architectural history and a small craft. Each envelope costs her roughly $2 (£1.58) to produce. She holds a master's degree in architecture from California Baptist University. She sent her first batch in September and by December, she had 1,300 subscribers.
