When you are looking at USPS service performance a week at the time it can be hard to detect trends. You really need to step back and look at larger time spans to get some definition.
SnailWorks began measuring aggregate data in May 2021, and used that data to determine on-time percentages and days to delivery for First-Class letters and flats, as well as Marketing Mail letters and flats. Our criteria for including a mail piece in our measurement was that the piece must have a valid start-the-clock event and be tracked to delivery. Since June 2021, we have included more than 4.7 billion pieces of mail in measurement, building what we feel is a very relevant sample set.
So, how is mail service looking? First-Class Mail is getting slower. Marketing Mail is more complicated.
First-Class Mail – Letters
We measure on-time percentage and days in transit from induction to delivery.
First-Class letters were delivered “on time” by USPS standards 93.8% of the time in the period from June 2021 through the end of that year. In 2022, First-Class letters were on time 92.3%, a decline of 1.6% although service standards were relaxed in October 2021. YTD in 2023 First-Class letters have been on time 91.2% of the time, another 1.2% decline.
So, overall, First-Class letters have been late 2.8% more often than in 2021, even against relaxed standards.
During that same time period, the average number of days to deliver a letter increased from 2.79 days in 2021 to 3.03 days in 2022, to 3.15 days in 2023 YTD. That turns out to be a slowdown of 13%.
First-Class Mail – Flats
First-Class flats are a little tougher to measure. Still, there is enough data to draw conclusions. Week-to-week, service performance for flats has been very uneven. But looking at the annual averages makes it clearer. In 2021 91.8% of flats were delivered on time by the same standards used for letters. That on-time percentage dropped to 90.0% in 2022, and has plummeted to 73.5% in 2023, YTD. Service on First-Class flats appears to be in a free fall.
Interestingly, the days-in-transit for First-Class flats don’t show as dramatic a deterioration, coming in at 3.37 days, 3.32 days, and 3.77 days in 2021, 2022, and 2023 respectively, a 12% slowdown.
Marketing Mail
Marketing Mail, happily, is a much better story. Its measurement is more complicated than First-Class Mail because it is often transported by mailers to a destination facility for entry, so it tends not to travel as far. We try to compensate for that by not including mail inducted and delivered in the same SCF.
The on-time percentage for Marketing Mail letters improved from 94.7% in 2021 to 97.4% in 2023, an improvement of 2.4%. Of course, standards are very generous for Marketing Mail, so they represent an easier target. Days-in-transit improved from 3.16 days in 2021 to 2.50 days in 2023. Do keep in mind that these are generally inducted closer to the delivery point than First-Class Mail. Still, anecdotally, we have seen very impressive transit times for Marketing Mail letters.
Marketing Mail flats also saw a small improvement in on-Time delivery, going from 89.6% on time in 2021 to 92.0 on time in 2023. Days-in-transit dropped from an average of 3.82 days in 2021 to 2.82 in 2023 (YTD).
Geographic Variances
Overall, we do not see great geographic variances except in certain anomalous situations. Still, it can matter where mail is inducted. Maps below compare service for First-Class and Marketing Mail letters inducted in North Texas, Anaheim, and Northern Virginia. Service from those induction points seems comparable, although, logically, it takes longer for mail from Anaheim to deliver in New Jersey than mail from Virginia.
Still, there are some areas that can be problematic. Marketing Mail entered in Palatine, IL doesn’t perform like mail inducted on the coasts. Most other Chicagoland facilities don’t fare much better.
So, what practical guidance can we get from all of this?
- First-Class letter service is declining, which is concerning. Although it is not precipitous, it bears watching.
- First-Class flats are more alarming. Service is very uneven and becoming more difficult to track.
- Marketing Mail service has remained very steady and has improved in many cases. It may be a valid lower cost alternative.
All these results are based on large, generalized samples – the only mail that really matters is yours. Tracking your own mail is more important than ever.
