According to a survey conducted by the U.S. Postal Service in 2017, approximately 73% of people check their mail daily. This is especially true for those in the 18-24 age group, with 80% of respondents saying that they check their mail daily. The survey also found that older adults were more likely to check their mail less frequently, with only 55% of those aged 65 and over checking their mail daily. This data suggests that, while most people still check their mail daily, younger generations are more likely to be doing so.
