3.6 million Christmas cards on the busiest days

This year, again, people are flooding the orange mailboxes with their Christmas greetings. On average, 3.6 million pieces of Christmas mail are sent daily during the weeks leading up to Christmas. This is over ten times the amount of regular consumer mail sent on an ordinary day outside the holiday season. This highlights the enduring value of Christmas cards and underscores the importance of sharing personal holiday wishes during this festive time.

Through wind and bad weather

Maurice Unck, Director of MailNL at PostNL, emphasises that capacity is temporarily expanded to handle the massive influx of Christmas greetings. “Processing all those cards is an impressive task, with our 25,000 postal employees—from sorters to deliverers—working tirelessly to ensure Christmas greetings arrive on time. Even colleagues from headquarters and additional temporary staff are pitching in this year. Whether it storms or freezes, our people are there, making this period truly special. This significant surge in volume shows just how important physical mail still is during the holiday season.”
