Postcrossing grew by 8.9% in postcards received in April compared to 2019.
In April 2021, 453814 received postcards were registered at postcrossing.com. That is an increase of 37,081 postcards or a plus of 8.9% compared to 2019. (source: www.postcrossing.com).
The year 2020 is difficult to compare due to the pandemic. Back in April 2020, the number fell to 249807, due to the many lockdowns due to COVID-19.
That is why I am comparing the pre-pandemic year.
A great development that postcrossing is becoming more and more popular.
Happy postcrossing!
