Postcards are among the most effective direct mail formats, as they strike a balance between simplicity and impact. Postcards have evolved from personal notes and travel mementos to strong tools for marketing and business communication.
The simplicity, affordability, and high engagement rates of postcards make them a standout medium. Postcards deliver a tangible experience, instantly capturing attention without requiring the recipient to open an envelope or click a link.
This guide will help you learn about postcards, their design, and several marketing use cases.
What is a Postcard?
A postcard is a rectangular piece of thick paper or cardstock designed to send messages without an envelope. Traditionally, postcards have been used for personal correspondence, as travel souvenirs, and to send short notes to friends and family.
Postcards first gained popularity for their convenient and low-cost method of communication. Travelers would send scenic postcards from holiday destinations, and personal notes would reach loved ones quickly without the worry of envelopes. Businesses use postcards to announce new products, promote special offers, send reminders, and even run targeted campaigns using variable data printing and QR codes.
For example, a local bakery might send a colorful postcard featuring a discount for first-time customers. At the same time, a software company may use postcards to promote a new app to a segmented mailing list. Businesses can design, print, and mail these campaigns with the assistance of expert mailing services, such as Compu-Mail.
