Knowing the weight of a Gmail and Outlook email

The weight of an email is made up of the html file and images. The html file weighs only between 20 kb and 60 kb, the total weight of the mail is mainly increased by the attachments.

What is an email made of?

For all the messaging systems, whether it is Gmail, Outlook or others, an email is composed of:

  • An e-mail address of the sender or the transmitter of the message.
  • An e-mail address of the recipient, i.e. the address to which you are sending the message, including in CC and CCI
  • The date the message was sent. Please note that if not filled in, the mail server will add it.
  • Received: this is information about all the mail servers through which the mail has passed,
  • Reply and forward.
  • The subject of the message.
  • The body of the message which concerns the message to the recipient.
  • The attachments.
