100% Working Method to Send Backdate Mail in Gmail | Permanent Change Sent Date in Your Gmail ID
What if you forget to send an urgent mail that can’t be accepted later? You might get no response. Also, what if you have already sent that mail but the recipient receives it late? Who’s to blame then? Sender or receiver? Here, only the internet would be at fault. That’s where you might need to send Backdate Mail in Gmail.
Now, whether you skipped submitting your online assessments to your teacher’s Gmail id or forgot to send a mail that needs to be sent 10 minutes ago or even a decade ago, there’s still a chance to send it again with a past date.
To send Backdated Emails in Gmail, you need to set up Burp Suite and also get the SwitchyOmega extension. Then, you will also need to install the CA Certificate. Then you will be able to change the timestamp in your Gmail using the epoch converter website.
We know that you are still quite confused about the procedure, and that’s why you can move ahead to read this full-fledged guide on this query.
How to Send Backdate Mail in Gmail? A Step-By-Step Guide
Can we send backdated email? No, We are not asking you to change the Date & Time on your Computer or talking about any photoshop or editing mail date in elements. These methods are already mentioned on some authority-ranking blogs on Google. All these are useless.
Because of Google’s bug, it is possible to send an email with a past date. The method to change the send date on an email is complicated, but it isn’t actually that tricky with this tutorial. You just need to change the timestamp in Gmail.
Prerequisites To Change the Sent Date on an Email
- A personal computer or laptop
- Must have Chrome installed on it. You can also use other browsers as well, but Chrome gives more compatibility.
- Set Up Burp Suite and a CA certificate.
- Install SwitchyOmega extension.
- Your Gmail account to modify the email
- Ultimately, PATIENCE.
In order to make it look like you have already sent an email, you need to follow the steps carefully to make sure that no errors should occur.
Setting Up Burp Suite

- Install the software Burp Suite and run it.
- Click on Temporary project and hit next.
- You’ll be asked to select the configuration to load the project. Use Burp Defaults and Start Burp.
- Wait for a few seconds and let the Burp Suite install.
- Click on the Proxy button and copy the server and port code in a notepad. It will be 127.0.0.1:8080. (Here, the server is 127.0.0.1 and the port is 8080).
Installing SwitchyOmega Extension

- Head towards your chrome browser and install SwitchyOmega in it.
- Open SwitchyOmega and add a new profile under the profile section.
- Set the profile name to burp or anything, choose the Proxy Profile option and click create.
- Under proxy servers, choose protocol HTTP, and add server and port code as mentioned above.
- Tap on “Apply Changes“.
Installing CA Certificate

Half of your work is already done. Currently, you need to install a CA Certificate in your Chrome. To do this,
- Enter this code(127.0.0.1:8080) in the URL and you’ll be redirected to a Burp Suite Community Edition page. Click on CA Certificate and download it.
- Click the downloaded file and open it.
- Hit Install Certificate.
- Click current user and press next.
- Choose option 2 and click browse. Select Trusted Root Certification Authorities and press next.
- Again press next and click Finish. You’ll see a pop-up with a message – the import was successful. It means you have successfully installed the certificate.
- Now is the time to send mail in Gmail according to your desired date.
Steps to Send Email in Gmail With Previous Date
- Before you perform any action, open this epoch converter website in your browser. It allows you to change timestamps in Gmail.
- Open your Gmail in another tab and compose a new mail to the recipient mail ID.
- After composing the message, click on the schedule button and set a scheduled date(Just set a date, don’t press the send button). Here we will capture and manipulate the request.
- Run the Burp Suite and switch towards the proxy option. Make sure that the intercept is on.
- Click on the SwitchyOmega extension in Chrome and choose burp.
- Now press schedule Send and check the Burp Suite. It will capture the request which will look similar to this.

Note: Press the forward button again and again until you find your request.
- Once you get it, check the timestamp which will look like this number “1600859289000”. You have to change it accordingly by visiting the epoch converter. There, set your desired back date accordingly and press Human Date to Timestamp.
- Copy the given timestamp in milliseconds and replace it with your three existing timestamps.
- Just click the forward button and turn off the intercept.
- Congratulations, you successfully sent the mail on the past date.
You can change your desired backdate accordingly but the actual receiving date will be shown to the recipient. However, even if the receiver checks your mail info, he will find the original sent date as you had set.
In an era where over 304 billion emails are sent and received every day, sometimes it is acceptable if one mail gets delayed due to a technical glitch. Just make sure to not mess with a techy person.
“Backdating is usually not allowed and even can be illegal or fraudulent in some situations. However, there are times when backdating can be acceptable, but the parties involved must agree to it”. - Investopedia.
Thanks to Jasminder Pal Singh for finding this Google bug. He has also made a short video on this tutorial but honestly, it didn’t work for me, as the burp setup, CA certificate installation, and using SwitchyOmega were not mentioned in it.

I am facing problem to complete this process.. Internet is not working due to this proxy address.. Please help its urgent…
Please elaborate on which step you are facing the issue.
However, make sure you have followed all the steps carefully.
Rest, internet will not work after using proxy. That’s why I’ve told to open the time converter website and compose mail before you switch proxy.
After you capture the request and turn off the intercept, your internet will work.
Use quick and dirty proxy flipper extension.
Thanks for mentioning.
Thanks @jasminder for finding out this bug.

I have already composed mail & opened time converter as well ” but when I am starting SwitchyOmega then gmail lost connection ” so the burp suite can’t catch it & I could not modify the time stamp.
Please Help regarding this
Hi
Please check if you have installed CA certificate to your browser.
Also, use Quick and Dirty Proxy Flipper.

I hope it helps.
Hi, I have already installed CA cert, still no working. You said about using Quick and Dirty Proxy Flipper, That also have been installed too but there is no option for me to make a profile like switchy omega,,. I am using windows 10 & updated chrome, I think that could be the reason, what is your idea?. Thanks in advance.
I have successfully done the process.. but in the reciever end mail recieved at correct time,
The manipulated time is shown in the original message option.
Hi
So the thing is, you’ll see the exact backdate mail in your sent box. While on the receiver’s end, you may see the sent backdate mail by clicking “show original”.
I am getting to the halfway point when I hit download for Ca Certificate but I am getting an error in Keychain Access. Please help Thank you.
Just download the CA Certificate. Don’t install it directly. Instead, go to your certificates section in chrome or another browser and upload the certificate there.

Comment
Dear Steve hi, this is a Mayday message, it took me days to get to your site and you are my last hope (this is not me being dramatic, Imight lose my job). So far Imade it to the step 6 but I never got the coded message in the burp suite windows, nothing such as your screenshot shows up. I am awfully sorry to bother you and at the same time very very grateful for what you do. My email has to be in my outbox tomorrow by 2/00 PM Paris time. Many thanks in advance for your kind help. I am terrible at computers 🙁
hi, me again
If it might helps the error message is “the client fail to negociate a tls connexion”
Thanks
hi did you received my comments? I cannot make it after step 6 the message says ubable to make a tls connexion. please help. thnak you so
Ok, follow these steps Anne. It will work:)
(I’m assuming you have already downloaded the burp suite, installed the CA certificate and properly added the server and port in switchy omega)
Note: Make sure to open epochconverter.com in a separate window first.
Step 1: Open burp suite and turn intercept off.
Step 2: Head towards your chrome and turn on proxy in SwitchyOmega.
Step 3: Compose a mail and set any scheduled date.
Step 4: Go to burp, turn on intercept and now click on schedule send button in gmail.
Step 5: Again go to burp and click forward again and again until you find your composed mail and those three timestamps.
Step 6: Once you find it, replace those timestamps with your current ones.
Step 7: Click forward and turn intercept off.
Hi Steve thank you so much for getting back to me, I probably miss some settings in the steps for I’ve been following the process and I still get the unable to make a TLS connection
Sorry to bother
Best
Anne
