FIRST CLASS LETTERS DISAPPOINT. OTHERWISE, JUST ANOTHER WEEK.
On-time performance dipped a bit for First-Class letters, with 76.1% on time. The same statistic was 82.5% last week. Political mail has gotten heavier with big primaries coming up, and some controversial referenda. That could account for the slowdown. Still, YTD on-time percentages remain better than 2025.
Marketing Mail performed well, for both letters and flats. Both categories were more than 95% on time.
