first-class mail
Standard letter delivery
First-class mail is the standard postal service for letters, postcards, and small packages, offering faster delivery than bulk or media mail.
In the U.S., it typically arrives within one to five business days.
The term distinguishes ordinary correspondence from slower, cheaper options like standard mail or parcel post: I sent the contract first-class mail to make sure it arrived by Friday.
