Was there mail service yesterday

I'm just an AI, I don't have access to real-time information about mail services or their schedules. However, I can provide some general information about mail services.

In the United States, the United States Postal Service (USPS) typically operates on a regular schedule, including weekends and holidays, except for certain holidays like Christmas Day and New Year's Day. However, it's possible that mail delivery may be delayed or suspended due to inclement weather, natural disasters, or other unforeseen circumstances.

If you're wondering whether mail was delivered yesterday, you can try checking with your local post office or contacting the USPS customer service number (1-800-275-8777) to see if they have any information about mail delivery in your area.
