You can't get the corona virus from the mail. For a virus to stay active, it requires a specific combination of environmental factors, including the right temperature, a lack of UV exposures, and humidity. Because mail is exposed to so many different environments while in transit, it's very unlikely that the virus can remain viable on your mail. The CDC's official line is that the virus is spread through respiratory droplets and there's very low risk of getting it through the mail.
