About this question

I just noticed a strange email in my sent folder that I did not send. Here is the header information:


To: 5f3d36eb61801dda4063@cloudmailin.net

From: ********@gmail.com

Date: Mon, 10 Jun 2019 06:54:17 -0700

Message-ID:

Subject: bW9KRGdIeTlyMFd2UjZQQVYrQUd0TVJ5N2IrbDlqVXh2NlF6ZUFvaDlaanpRQWwzVmZtVFlwQVo5cXUybmRFbC0ta0VvVDdmakJzVzQzL3lQM2lYL0tBQT09--19cd1b1aa0f32659eece53630df822281b44c804

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 7bit

Content-Disposition: inline

This message was automatically generated by Gmail.

There was no content in the email, just the jumble of characters in the subject. The email address this was sent to is reported a few times on the internet as possible phishing, but it's not clear to me why Gmail would automatically generate an email on my behalf to this address. The "From" field was indeed my actual email address.


I have already changed my password as a precaution, but I am curious is this anything to worry further about?

If you found the message "This message was automatically generated by Gmail" in your Sent folder, you might be wondering why it appeared and whether you should take any action. Here’s what you need to know:

Why Does This Happen?

  • Gmail Auto-Responses: Gmail sometimes generates automatic emails, such as delivery failure notices or security alerts.
  • Forwarding or Filtering Rules: If you have email forwarding or filters set up, Gmail might be generating messages on your behalf.
  • Third-Party Apps: If you’ve granted access to third-party email apps or services, they might be sending automated emails using your account.
  • Gmail’s Vacation Responder: If you've enabled an out-of-office reply, Gmail might be sending automatic responses.

What Should You Do?

✅ 1. Check Email Content

  • Open the email and check if it looks like a system message from Gmail.
  • If it contains delivery status notifications (e.g., failed email delivery), it's usually harmless.

✅ 2. Review Connected Apps & Services

  • Go to Google Account → Security → Third-party apps with account access.
  • Revoke access for any suspicious apps.

✅ 3. Check Your Gmail Filters & Forwarding

  • Go to Gmail Settings → Filters and Blocked Addresses and Forwarding and POP/IMAP.
  • Look for any unusual rules that might be causing auto-generated emails.

✅ 4. Scan for Security Issues

  • If the email seems suspicious, change your Google account password immediately.
  • Enable 2-Step Verification for extra security.

Final Thoughts

  • If Gmail generated the email for delivery status or vacation replies, no action is needed.
  • If it's unexpected, review filters, third-party apps, and security settings.

If you found a message in your Gmail "Sent" folder that was automatically generated by Gmail, it's important to understand what kind of message it is and why it was generated. Here are some steps you can take:


Review the Message Content: Open the email and read through it to understand what the message says. Gmail might generate automatic messages for various reasons, such as delivery status notifications, vacation responses, or alerts about suspicious activity.

Check Email Headers: Look at the email headers to see where the email originated from and to confirm that it was indeed generated by Gmail. You can do this by clicking on the three vertical dots (More options) in the upper right corner of the email and selecting "Show original."

Verify Recent Activity: Go through your recent email activity to see if there was any action you took that might have triggered the automated message. For example, setting up a vacation responder or a filter that sends automated replies.

Security Check: Ensure your account is secure. Check for any unauthorized access by visiting your Google Account's "Security" section (https://myaccount.google.com/security-checkup). Look for any unfamiliar devices or activity.

Gmail Settings: Review your Gmail settings, especially under "Filters and Blocked Addresses" and "Vacation responder" settings. There might be rules or automatic replies set up that you forgot about.

Search for Information: If the email's purpose is unclear, search for specific phrases from the email message in Google's help documentation or forums. Other users may have encountered the same situation and could provide insight.

Contact Support: If you cannot determine why the message was generated and are concerned about it, contact Google Support for further assistance.

Taking these steps should help you understand why the message was generated and what, if anything, you need to do about it.
