Email: The Digital Communication Tool

What is Email?

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.

How Does Email Work?

Email works by using various protocols and servers to send and receive messages. Here’s a simplified overview of the process:

Composing and Sending

You write an email using an email client (like Gmail, Outlook, or Yahoo Mail) and hit send.

SMTP Server

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).

Benefits of Email

Universal Accessibility

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.

Cross-Platform Support

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.

Asynchronous Communication

Unlike phone calls or instant messaging, emails do not require both parties to be available at the same time, allowing for more flexible communication.

Record Keeping

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.

Protocol-Based Communication

Email operates on standardized protocols (SMTP, POP3, IMAP), ensuring that different email systems can communicate with each other reliably and efficiently.

FAQ - Frequently Asked Questions

What is transcription process?
Each audio file is tested, transcoded, and then transcribed using the Whisper model from the OpenAI API.
How long does it take to get a transcript?
The processing time for your transcript will depend on the length of the audio file. Typically, shorter voice messages can be transcribed quickly using OpenAI speech-to-text API.
What are the maximum file size for transcription?
Note that our transcription service has a file size limit of 20 MB.
What is the maximum duration you can transcribe?

We currently have a file size limit of 20MB. 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:

Duration ( seconds ) = File Size ( bits ) Bitrate ( bits/second )

Applying this equation to our 20MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 43 minutes and 41 seconds. To easily calculate durations for different file sizes and bitrates, you can use our audio duration calculator.

Do I need to transform the audio before sending it to my email address?
No, this is not necessary. will automatically transcode your audio file upon receipt into the format expected by the OpenAI API.
Can ChatGPT transcribe audio to text?
Yes, ChatGPT can transcribe audio to text, but there are more specialized AI models specifically designed for this task, such as Whisper. Whisper is a state-of-the-art transcription tool that offers higher accuracy and efficiency in converting audio to text. If you're looking for the best results in audio transcription, Whisper is the ideal choice.
Why transcription over email?
Our email-based automatic transcription service is designed to break down barriers and provide universal access to voice message transcription. By leveraging email as our input and delivery method, we're making it easy to automate and integrate with existing platforms. Since email is an established communication method, it's likely to persist, offering longevity.
