Email, short for electronic mail, is a method of exchanging digital messages between people using electronic devices. It’s one of the most widely used forms of communication, allowing users to send and receive messages instantly from anywhere in the world. Emails can include text, images, files, and links, making them a versatile and essential tool for both personal and professional communication.
Email works by using various protocols and servers to send and receive messages. Here’s a simplified overview of the process:
You write an email using an email client (like Gmail, Outlook, or Yahoo Mail) and hit send.
The email is sent to your email provider’s SMTP (Simple Mail Transfer Protocol) server, which forwards it to the recipient’s email server.
The recipient’s email server receives the message and stores it in their inbox, where it can be accessed via an email client using protocols like POP3 (Post Office Protocol) or IMAP (Internet Message Access Protocol).
Email clients are available on almost all devices, including smartphones, tablets, and computers. This makes it easy to access your emails from anywhere, at any time.
Emails can be sent and received across different platforms and operating systems, ensuring compatibility and ease of communication.
Sending an email is generally free, making it a cost-effective way to communicate, especially for long-distance and international messages.
Unlike phone calls or instant messaging, emails do not require both parties to be available at the same time, allowing for more flexible communication.
Emails provide a written record of communication, which can be useful for keeping track of conversations and important information..
You can send files, photos, and other documents as attachments, making it easy to share resources.
Email operates on standardized protocols (SMTP, POP3, IMAP), ensuring that different email systems can communicate with each other reliably and efficiently.
We currently have a file size limit of 10 MB. Given that most voice messages are encoded with a constant bitrate and a single channel (mono, no stereo), we can calculate the maximum duration of a file using the following equation:
Applying this equation to our 10 MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 21 minutes and 51 seconds. To easily calculate durations for different file sizes and bitrates, you can use our audio duration calculator.
