How to Delete a Sent Email?

We've all been there – one too many clicks, and you've sent an email by mistake. Oh, the horror! In that moment, you feel your life flash before your eyes... But don't panic just yet, because solutions are possible.

Whether it's on Gmail, Outlook, or any other email platform, it can be stressful not knowing how to unsend or recall a message. Fortunately, there are solutions to correct these mistakes. From activating the unsend option to retrieving sent emails, we guide you through the essential steps to effectively manage your emails.

Can You Unsend an Email?

The short answer: yes!

It is possible to retrieve or delete a message sent by mistake, but you need to act quickly. The recall function also varies depending on the provider of your email address.

Understanding How Sending an Email Works

Sending an email may seem simple on the surface, but it's actually a fairly complex process that passes through several servers. When you click the "Send" button, the message leaves your outbox to be routed to your email provider's server (Gmail, Outlook, etc.). It then forwards the email to the recipient's server before it reaches their inbox. This transmission chain makes the magic of sending and receiving emails work, but it also makes the email cancellation process quite difficult.

However, some platforms offer features to delay sending or recall an email within a short window of time after sending. It's also important to know that specific protocols like SMTP, POP3, and IMAP govern how emails are sent and received, and they don't all work the same way. This, of course, adds another layer of complexity.

The good news is, you don't need too much technical knowledge, as these aspects are handled by the providers.

How to Modify a Mistakenly Sent Message?

To modify a sent message, you need to act quickly. Some email services like Gmail and Outlook offer options to cancel or recall a message shortly after sending it.

However, note that these options do not guarantee the modification or cancellation of the message, especially if the recipient has already opened the email or if you don't have Microsoft Exchange server access. If modification isn't possible, the best course of action is to contact the recipient directly and explain the mistake (prepare your best bouquet).

How Do I Recall or Unsend an Email in Outlook? Steps to Follow

To recall a message in Outlook and complete the recall process, follow these steps:

  1. Once your email has been sent, go to the "Sent Items" folder in your email.
  2. Then, locate and double-click on the message you want to recall to open it in a separate window.
  3. In the menu bar at the top of your screen (the classic ribbon), select the "Message" tab.
  4. Then, click on "Actions" in the dropdown menu.
  5. Select the "Recall this message" option. This is where you'll find the recall email option in Outlook.
  6. You will then have two options: either delete unread copies of this message, or delete these copies and replace them with a new message. Unfortunately, you won't be able to do anything for copies of the message that have already been opened. The sender will receive a recall status notification about whether the recall request succeeded.
  7. Select the option that suits you and click "OK".

And you're done!

What Happens When You Recall an Email in Outlook?

When you recall an email in Outlook, the system attempts to retrieve the message from the recipient's inbox before they read it. However, this only works under specific conditions:

  • Both you and the recipient must be using Microsoft Exchange within the same organization
  • The recipient must not have opened the email yet
  • The email must still be in their inbox (not moved to another folder or processed by a filter)

If you recall an email, does the recipient know? Yes, in some cases. If the recall fails, the recipient may receive a notification about the recall attempt. If successful, they typically won't know a recall request was made.

Why Does Recalling an Email in Outlook Fail?

The recall process can fail for several reasons:

  • The recipient has already opened the email
  • The recipient is not on the same Microsoft Exchange server
  • The email was moved to a different folder by a filter or rule
  • The recipient is using a mobile device or different email client
  • The recipient's mailbox is offline

Understanding these limitations helps set realistic expectations for the recall status of your message.

How Do I Recall or Unsend an Email in Gmail? Canceling the Sending of an Email

To cancel sending an email with Gmail or use Gmail undo send, the first step is to make sure this feature is enabled in your settings.

  1. Go to the Settings tab by clicking the gear icon in the upper-right corner.
  2. Then, click on "See All Settings."
  3. Once in the General tab, you'll find a section called "Undo Send." Here, you can set the cancellation time that seems most appropriate, with a maximum of 30 seconds.
  4. Once you've saved the settings, the feature will be activated.
  5. After sending an email, a notification will appear at the bottom of the screen with the option to cancel the send and will stay displayed according to the set time.
  6. You'll need to click "Undo" during the cancellation window to stop the email from being sent.

This Gmail undo send feature is much simpler than Outlook's recall function but has a shorter time window.

How Do I Recall an Email on Different Devices or Platforms?

The ability to recall or unsend an email varies significantly across devices and platforms:

Outlook Web Recall Email

The Outlook web version (Outlook.com) has limited recall capabilities compared to the desktop version. You can cancel sending within a brief window using delay settings, but full recall functionality requires Microsoft Exchange access and the desktop application.

Recall Email Outlook App (Mobile Device)

On the Outlook mobile app for iPhone and Android, direct recall functionality is not available. You'll need to access Outlook from a desktop computer to complete the recall process. However, you can set up delayed sending to give yourself more time to catch mistakes.

Recall Outlook Email Mac

To recall an email on Outlook for Mac:

  1. Open the Sent Items folder
  2. Double-click the message to open it in a separate window
  3. Go to Message > Recall this message
  4. Follow the recall process prompts

Note that the same Microsoft Exchange requirements apply for Mac users.

Recall Email New Outlook

The new Outlook for Windows has a similar recall process to the classic version, though the interface may look slightly different. Look for the Message tab in the classic ribbon or use the Actions menu to find the recall option.

Correcting an Error After Sending an Email: Tips and Advice

Sending an email is a near-instantaneous and irreversible process. However, when a mistake is made, certain measures can be taken to mitigate its effects. The main tip is speed. The quicker you act, the less chance there is of your message impacting your recipient, and the better your recall status will be.

Here are the basic reflexes you should have in case of a mistake:

  1. See if there's an option to cancel or recall your message via the integrated features of your email solution. Check if a recall request can be initiated.
  2. Send a correction email as a new message, explaining your mistake and providing the correct information. Depending on your recipient's mailbox settings and filter rules, this new email may also "bury" the previous one.
  3. Ask the recipient not to read or to ignore the message. Be cautious, as human nature being what it is, it's likely that the recipient's curiosity will be even more piqued. However, by doing this, you'll have at least warned them about the erroneous information in your message, especially if it contains sensitive information.

Ultimately, we can only recommend carefully checking your email before sending it. We always think twice before speaking, so why not read an email seven times? Especially if its content is sensitive... Make sure the right recipient is selected, the content is correct and complete, you have the right email signature in place, and all necessary attachments are included.
