Regarding the April 28 editorial “Ceding Saturdays”:

No, we should not end Saturday mail delivery. Eliminating six-day delivery would cause the U.S. Postal Service to lose customers and its competitive advantage while hurting senior citizens and rural America. Rather, we should make the Postal Service more competitive by allowing it to offer innovative new products and services that Americans want and need. Right now, the Postal Service can’t ship wine and beer, notarize documents, cash checks, provide secure e-mail services or perform other important jobs. This makes no sense. It’s time to provide the Postal Service the freedom to offer services that would benefit millions of Americans.

Additionally, the claim that the Postal Service is losing billions of dollars per year is simply not true. All of its “financial losses” since October 2012 are the result of a Bush-era law to prefund 75 years of retiree health benefits in 10 years. No other corporation or government agency is saddled with this $5.5 billion-a-year mandate. Without this onerous burden, the Postal Service would have made a profit of $623 million last year and would make more than $1 billion this year.

When the middle class is disappearing, we should not eliminate tens of thousands of decent-paying jobs by substantially slowing the delivery of mail. It is time for Congress to save the Postal Service, not dismantle it.

Bernie Sanders and Peter DeFazio, Washington

Mr. Sanders, an independent, represents Vermont in the Senate, where Mr. DeFazio, a Democrat, represents Oregon. They are sponsors of the Postal Service Protection Act of 2013.

Giving up one day of mail delivery every week is a sensible and apparently widely acceptable proposal, but that day should be Monday, not Saturday. Most people are at home on Saturday and thus enjoy receiving mail that day, whereas they’re generally away from home on Monday. Offices, meanwhile, could use that day to handle Saturday’s mail and prepare for the week ahead.
