The outbox folder is a space where all the outgoing messages are temporarily stored while composing a message the data automatically gets saved as a draft in your outbox.

On the other hand, the sent folder is the space where all your messages move once they have been sent to the recipient.

What is Outbox?

The outbox folder is the first step in sending a message. The outbox folder temporarily holds all the messages that you have formed.

It is a safe place for your messages as they remain there until a secure connection has been established between the mail server and the receiver. After composing a message, when it is sent, it directly moves to the outbox folder, where it stands on hold until a secure connection is available with the SMPT (Simple Mail Transfer Protocol) server leading to the connection being established.

The other messages which are also commonly stored in the outbox are the messages that have failed to successfully deliver to the recipient due to any internet connectivity issue. While the messages are stored in this folder, you can also further re-edit your messages if required, as the messages have still not been sent.

Once the mail server reconnects with the recipient and the message is successfully sent to the receiver, the message will no longer remain in the outbox folder and will transfer automatically to the sent folder.

 

What is Sent?

The sent folder is the final stage of sending a message. The sent folder commonly stores all the messages the sender has successfully sent to the recipient.

All the messages sent through the mail server are stored here. Unlike the outbox folder, the messages in this folder cannot be edited or deleted as they have already been delivered and received by the recipient. 

Various email clients have their tags to label the sent messages. For Gmail, it is commonly “sent mail”, whereas, for Microsoft Outlook, the chosen tag is “sent item”.

Most email servers choose “sent” folder as their default.

Main Differences Between Outbox and Sent

  1. The main difference between outbox and sent is that the outbox folder temporarily stores all the messages. They store it for a certain period, where the sent folder permanently stores all the messages the sender has successfully delivered.
  2. The messages stored in the outbox folder can be further edited or deleted as they have not been sent to the recipient yet.  Unlike the outbox folder in the sent folder, no further changes can be made to the messages as the recipient has successfully received the messages.
  3. Certain times due to connectivity issues between the email client and the mail service, the message gets stored in the outbox and is unable to be delivered; however, after the connectivity issue is fixed and the message is delivered, the message shifts to the sent folder.
  4. The messages in the outbox folder are waiting for a secure server connection to be established. In contrast, the messages in the sent folder have already secured an established connection and have been delivered to the recipient.
  5. The messages in the outbox folder are yet to be delivered, whereas the messages stored in the sent folder have already been delivered to the recipient.
