The mail service that is typically used for urgent communications is Express mail. This service is designed for fast delivery, often providing overnight shipping, which makes it ideal for time-sensitive documents and packages. Express mail often includes features such as tracking and delivery guarantees, ensuring that urgent communications reach their destination as quickly as possible.

Other types of mail services, such as First-Class mail, Priority mail, and Standard mail, do offer reliable delivery options, but they do not provide the same level of urgency as Express mail. First-Class mail generally takes one to three business days depending on the destination, while Priority mail typically delivers within one to three days but can vary. Standard mail, on the other hand, is often used for bulk mailing and is the slowest option available, making it unsuitable for urgent communications.
