The cost to mail a 4-ounce envelope depends on the service used and the destination. For domestic First-Class Mail, as of October 2023, the rate is typically around $1.40. However, prices can vary based on additional factors like package dimensions or if you choose services such as priority shipping. Always check the latest rates from the USPS or your local postal service for the most accurate pricing.
