When we started Mailrun in 1987 and incorporated in 1989, our goal was simple: provide our customers with dependable service, personal attention, and a commitment to getting the job done right.

Nearly four decades later, I am proud that those same values continue to define our company. Mailrun has grown from its early beginnings into a trusted delivery company that has successfully completed millions of deliveries.

In 2018, we expanded with Mailrun Express, adding overnight, second-day, and ground shipping options to better serve the changing needs of our customers. While our technology, services, and capabilities have evolved, our philosophy has not: take care of our customers and earn their business with every delivery.

I am incredibly proud of what we have built and grateful to our customers, employees, drivers, and partners who have been part of our journey.

Thank you for trusting Mailrun Courier Service. We look forward to serving you for many years to come.

Sincerely,
President,

Cynthia Hartman
