What is a major disadvantage of mail as a communication method?

The major disadvantage of mail as a communication method is that it takes time for delivery. Unlike instant forms of communication such as email or messaging apps, traditional mail relies on physical transport, which can lead to delays. This lag in communication can be problematic for time-sensitive information or urgent matters that require a quick response.

Although mail can serve various purposes such as advertising or reaching a wide audience, these factors do not outweigh the time it takes for letters and packages to be delivered. Additionally, while some modern forms of communication require a computer, traditional mail does not have that limitation, making it a more universally accessible option despite its slower delivery time.
