How to Send an E-mail With a Previous Date

Nowadays, emails are essential for communicating. It’s among the best ways to exchange important documents and notes with your friends, family, and colleagues at work. If you frequently send emails for work, you may schedule a few to streamline your workflow. 

However, what if you forgot to send an important email before the deadline? Wondering if there’s a way to send an email with a previous date? There are a few ways to backdate an email, including changing the date and time on your computer, using Inspect Element, or creating an SMTP server.

In this post, we’ll discuss a few ways that you can use to send an email with a previous date.

1. Change the Date & Time on Your Computer

One basic way to send an email with a previous date is to change your PC’s clock to the time you are trying to simulate before sending the email. Some older email clients like Outlook Express will accept this date and send it to the email server with the local date and time.

Here’s the procedure:

  1. On a Windows computer, right-click on the clock on your desktop.
  2. Select Adjust date/time.
    Windows Adjust date/time option
  3. Change the date to whatever you need it to be and click Okay.
    Windows change data and time
  4. Write and send your encrypted email.

You can try the above trick on Mac with one of the many mail clients available for macOS.

Why This Method May Not Work

While this method may work, the email metadata will still contain the correct date. As such, this method may fail for several reasons:

  1. Depending on your email setup, your email provider may also overwrite the time and date.
  2. Subsequent relay servers (the computers that send your email toward its destination) will ignore the timestamp from the computer and use the server time anyway.
  3. The metadata from your email server will show when it received your email, not when you wrote and sent it.
  4. The receiving email server will still stamp the correct receipt time before it heads to the recipient.

For example, in the image of an email’s metadata above, the real-time and date are included four separate times:

  1. Delivery date: Thu, 08 Sep 2016 17:31:45 +0100.
  2. Received: from mail by with spam virus-scanned (Exim 4.80.1) for EMAIL ADDRESS; Thu, 08 Sep 2016 17:31:45 +0100.
  3. Server (version=TLS1_0, cipher=TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P384) id 15.1.609.9; Thu, 8 Sep 2016 16:31:40 +0000.
  4. Received: from 15.01.0587.013; Thu, 8 Sep 2016 16:31:40 +0000.

To view metadata for any email in Gmail, click the three dots in the top right corner of the email. Then, click Show original. As you can see from the screenshot below, the metadata will display the correct date and time for each stop the email makes on its way to the recipient.

2. Creating an SMTP server

So, the email server will put the correct date and time stamp on your email, but what if you can set up and control your own email server?

Email works using the Simple Mail Transfer Protocol (SMTP) and SMTP servers, which are not incredibly difficult to set up or use.

If you have an earlier version of Windows, particularly a server OS such as Windows Server 2000, you may already have an SMTP server on your PC. All you have to do is turn it on and configure it to send your emails.

However, Windows 10 no longer includes an SMTP server. Fortunately, there are a lot of free SMTP server programs out there that you can download for free. This is rather a lot of trouble to go through to get an email date to look different, but if it’s really necessary, this may be the only way.

Note that you must own a domain to use this procedure!

3. Using hMailServer

hMailServer is one of the most popular free email servers. Here’s a quick rundown on how to install and configure it.

  1. Get the latest version of hMailServer and download it.
  2. Run the installer. You can accept the default values.
    hMailServer installation
  3. Be sure to note your administrator password, as you will need this later.
  4. Click Finish to complete the installation.
    hMailServer installation finish
  5. In the hMailServer interface, click the localhost, click Connect, and enter the password.
    hMailServer server password
  6. Click the Domains tab.
    hMailServer Domains
  7. Select Add Domain.
    hMailServer add domain
  8. Enter your domain name and click Save.
    hMailServer save domain
  9. Click the domain name in the domain list on the left-hand side of the interface, and then click the Accounts subfolder.
    hMailServer accounts
  10. Select Add and enter the account information for the email account you are going to create on your domain.

To set up the actual mail transfers, you must get information from the ISP with whom you’ve registered the domain.

4. Using Inspect Element to Modify Webmail

If you are using Gmail or another webmail client, use Google Chrome’s Inspect Element feature to temporarily modify the HTML code that displays an email on the screen, then take a screenshot of the displayed email to prove that the email has a particular date on it.

Remember that this is essentially forgery, so be aware of your legal liability when engaging in this behavior.

  1. Open the email you want to modify in your Gmail account.

  2. Right-click on the displayed date and select Inspect from the context menu.
    Inspect elements email
  3. Double-click on the time text under the grid cell in the Element Inspector and change the text to the date and time you want the email to display. The text in the email itself changes when you hit Return in the Inspector.
    Email inspect elements
  4. Quickly take a screenshot. The element will only display for a few seconds before Chrome changes it back to what the source HTML tells it is the true text.
  5. Trim your screenshot just to show the email with the modified date.

Just A Little Help says:
There is an easier way to do this. If you haven’t sent the email yet just change the date and time on your PC to when you needed the email to be sent and then send the email. Once the email is sent you can change the date and time on your pc back to normal and it’ll say that you sent that email however many days ago the date you put was. Also, the best part is it won’t change back to the day it actually is.

May i know what email app u use?
JJ says:
I have the same question, because when I use that method with Outlook, the correct date still appears on the email, evn though the system date has changed.
AP says:
Saved me from my mom getting suspicious over an homework issue where I didn’t submit it on time. I just sent the email to a wrong email, then I just used inspect element to change the sent time to 12:37 PM and omitted 1 “i” from the correct email turning it into a wrong email, and deleted the bounceback, and used inspect element again to change the email address to look correct. Also saved me from teachers wrath, because I sent a screenshot to her, and she blamed herself for the issue.
