Which method is used to send correspondence in a typical application?

In a typical application, sending correspondence via email is the most common and efficient method. Email provides a quick and reliable means of communication, allowing users to send messages, documents, and other attachments instantaneously compared to traditional postal services, which can take days for delivery. Furthermore, email systems can often be integrated into business applications, enabling automated correspondence for notifications, updates, confirmations, and other communication needs. The versatility of email allows it to be used for both formal and informal communication within an organization and with clients.

While other methods such as postal service, messaging apps, and fax can also be used for correspondence, they tend to have limitations in terms of speed, accessibility, and integration with automated processes, making email the preferred choice in most application scenarios.
