[Gmail TIP] How to avoid IP tracking (means to confirm email receipt)

Some of the messages received by Gmail can be exposed to your computer's IP information or other information (such as which browser you use, what mail app you use, IP address information, etc.) without knowing it at the moment you read it. .

When receiving e-mail, you may be tracked to the sender's IP (if you send your computer's IP unintentionally when you receive the e-mail).

Fortunately, the Gmail system provides a way to prevent other parties from secretly tracking caller IP.

There is a technology that email service systems use as a way to determine whether a recipient has read the mail they send. After inserting an invisible image (pixel) in an e-mail message, when the mail contents are opened, the image is accessed and the recipient's IP address is tracked to obtain the location information.

Gmail can let you decide whether or not you want to selectively display the images included in your mail content, in a way that prevents you from inadvertently tracking IP addresses. If there is a suspicious image in the text, the image can be suppressed.

Therefore, if you do not want the sender of the email (including email system users other than Gmail users) to accept the mail receipt request, you can suppress the images included in the body text.

To disable automatic display of external images in Gmail, you can do this in Gmail -> Settings ->General-> Images.



In this case, when the mail sender sends an e-mail asking to confirm receipt of the e-mail without knowing it, the following indication is displayed when receiving e-mail from Gmail.

If there is only text in the message body, but "Images are not displayed, it is likely that this message is the message that the other person has requested to acknowledge whether the message is opened or not. In this case, you do not have to display the image if you do not want to be notified of your receipt status.


In Gmail, the images contained in the message body provide a means of tracking outbound IP, or provide a number of security mechanisms to block information hacking using image insertion. For more information on this, please refer to the articles provided by Google.

[Tip:Chrome Device Management ] Chrome Release Channel best practices

While the majority of your users will be on the Stable channel of Chrome OS, if your organization has a large number of Chromebooks, there are several reasons why you should always keep some devices on the Beta channel:

Google recommends that you keep most of your users on the Stable channel, and 5% of your users on the Beta channel. We also recommend you keep your IT team on the Beta or Dev channels.

There are three types of Chrome OS releases: Stable, Beta, and Dev. You can set the release channel for your Chrome device users in the Admin console under Device management > Chrome > Device Settings.

Keep 5% of your organization on the Chrome OS Beta channel

While the majority of your users will be on the Stable channel of Chrome OS, if your organization has a large number of Chromebooks, there are several reasons why you should always keep some devices on the Beta channel:
  • Your organization will get a 4-6 week preview of new features.
  • Some features you discover may require you to communicate additional information to your organization.
  • Some features may not be suitable for all of your users, and you may need to investigate ways to block these features.
  • In some cases, you may find issues which could impact the use of the devices in your environment. Finding this out early enough with fewer devices will give you enough time to contact Google, and if we can’t resolve the issue, block the update before it hits all of your users.
As a general rule, we recommend you keep at least 5% of your devices on the Beta channel at all times. If you have multiple types of hardware, we recommend you keep 5% of each type of hardware on the Beta channel.
Google will actively investigate issues on the Beta channel. Please contact Enterprise support to report any issues that you notice.

Keep your IT staff on the Beta and Dev channels

In addition to keeping most of your IT staff on Beta channel, it can be helpful to keep some devices on the Dev channel, which will give you 9-12 week preview of what is coming to the stable version of Chrome OS. Benefits of being on the Dev channel include the following:
  • Your IT staff can test to make sure that your apps and systems are compatible with the latest Chrome OS software updates and feature changes.
  • While we automatically fix most issues before the release is marked as stable, we may not be able to catch all the corner cases which may uniquely impact your environment. Should any issues arise, your developers and IT staff can identify and report (via the Chromium site) any changes that may impact your environment before they reach the Beta or Stable channel.
Note that the Dev channel, by its nature of being an early release of Chrome, is not 100% stable, and should be used by IT staff or developers. Since some instability is expected, the Dev channel is more useful for staying aware of upcoming features in the OS.

How to set Chrome policies for users.

As a Chrome administrator for your organization, you can set policies for how people use their Google Account on a Chrome device, an Android device, or the Chrome browser. These policies are cloud-managed, so they apply when signing in from a personal or public device. The policies don't apply to users signed in as guests or with a Google Account outside of your organization (such as a personal Gmail account).
You can also set device-level policies on corporate-managed Windows®, Mac®, and Linux® computers.
Android apps can run on Chrome OS on supported device models only. We are constantly adding support for new devices. To allow your users to run Android apps, you must enable Android apps on supported Chrome devices in your organization.

Before you begin

For Chrome user policies to work on Windows, Mac, or Linux computers, Chrome Management must be turned on in your Admin console.
  1. Sign in to the Google Admin console.
  2. From the Admin console dashboard, go to Apps > Additional Google Services.
  3. Next to Chrome Management, click Settings .
  4. Choose ON for everyoneON for some organizations or OFF.
    For more detailed steps, see  Turn Chrome Management on or off.
If you purchase Chrome device management licenses: Chrome policies still apply for users who sign in to a managed Chrome device, even if Chrome Management is turned off.

[TIP] What is Smart Lock on a Chromebook and how do I use it?

Using Smart Lock on your Chromebook



If you are a frequent user of a Chromebook, the boot speed is very fast when you turn on your Chromebook and you must enter it each time on the sign-in screen.


The Smart Lock feature on your Chromebook is designed to ease this inconvenience. This means that if you have a smartphone near your Chromebook, you can sign in without a password.


To enable this feature, your smartphone must be at least Bluetooth-enabled Android 5.0, and your Chromebook must be Chrome OS version 40 or higher.


On your Chromebook, you'll need to select Settings menu> Show advanced settings> Use Smart Lock for Chromebook (Beta). When it is selected to use, search for a Bluetooth-enabled smartphone in the vicinity and select the desired smartphone.


After your Smart Lock setup is complete, if your smartphone is nearby and you're signed in, your Chromebook's login status will also be unlocked as shown in the screen below, in which case you can sign in directly without entering your password by clicking the login picture with your mouse. If your smartphone is logged out or powered off, your Chromebook's login will also require a password to sign in.

On your smartphone, you need to set up Settings> Security> Smart Lock> Trusted device.

[Tip: Attachments in Gmail] Update an incorrectly sent attachment (like MS Office/PDF files) without resending

When sending an attachment via Google Gmail, the file size is limited to 25MB.
In other words, files that can be sent as attachments can not be sent over 25MB in size. If you send attachments in the traditional way, if the contents are incorrect after the send, or if the sent attachments are modified, you have to resend them.

However, with GMail, attachments can be sent as links via Google Drive.
The original file exists in my Google Drive and only the link information of that file is sent. This allows G Suite users to send links up to 5TB.

I upload all attachments on the drive and send them in a link. In particular, PDF files and MS Office document files will be sent by this link method. Sometimes, after sending a link to an MS Office document or a PDF file, the originals may be wrong and you may need to resend the revision.

In the old days, you would need to modify the file and send it back to the recipients, but with version control in Google Drive, you can use version control to add the latest version of the file to the document Just upload.


When sending attachments from Gmail, send them via Google Drive as in the image above.



Like PDF documents, non-Google document formats on Google Drive can take advantage of version control. You can upload and maintain multiple versions of a document. These documents, which are delivered as links, will maintain the latest version of the document if the uploaded version of the file is uploaded without any changes to the link.

Compare core Google+ and G Suite Google+ features

Google+ has features for end users and  for business G Suite versions. Let's review the differences between Google+ for end users and Google+ for G Suite.



Compare core and business features


Google+ includes business features in addition to the same core functionality as the consumer version of Google+ for G Suite customers. With Google+, you can restrict Google+ to only certain users, control whether you share data with users outside your domain, and manage your social collaborations in a variety of ways.
.G Suite Administrators can perform the following functions:
  • Turn Google+ on or off for everyone or for a specific user.
  • By default, keep your posts and communities outside of your organization's domain.
  • Correct the age of the user who mistakenly entered it incorrectly when signing up.
  • Controls whether search engines index user profiles.
  • Control whether third-party apps use the Google+ API.
  • Manage your Google+ profile. For example:
    • Identify who has a Google+ profile in your organization's domain.
    • Create and manage Google+ profiles for users in your domain.
    • Block users from changing their Google+ profile name.
Google+ users in your organization can:
  • Easily share content internally with everyone in your domain without having to add everyone in your organization to your circles. Together with your shared circles, your organization's domain name will be shown to users as a sharing option.
  • You can override the default sharing settings for individual posts and communities.
  • Update your profile search feature settings.
  • Profile labels recognize different Google+ users in your domain, so you can easily distinguish them from individuals or other external profiles.
  • Restrict posting to your organization's domain only. People who have received private posts will not be able to reshare this post with users outside of your organization.
If you use Google+ within a domain, just like the images below, it will only give you the ability to organize communities within your domain. In addition, communities created within a domain can be made public within the domain or privately. Communities that are created privately in your domain can only be secretly engaged in community activities. Private communities are not exposed through search within the domain. Only members who are secretly subscribed can be made available. This is one of those features not available for regular Google+.

[Maximum file size of one file that can be stored in Google Drive]

G Suite users are often confused. What is the maximum size of attachments that you can currently send through Gmail? As you already know, attachments in gmail can only be sent up to 25MB. However, it can be confusing if the size of the file you can send to a URL link via Google Drive is 10GB, 1TB, or 5TB.

In Gmail, the maximum size of a file you can send as an attachment is 25 MB. However, if you want to send files over 25MB in size, you can use Google Drive to save the file and send the file as a URL link. At this time, the maximum size of one file that can be sent as URL link can be up to 5TB. (In the past, 10GB, 1TB, now up to 5TB) In other words, the maximum size of a file that can be stored in Google Drive is 5TB.

The maximum file size limitation of G Suite Basic, G Suite Business (Unlimited) and G Suite for Education are the same.
