What is Gmail Logger?
Gmail Logger is a powerful Python script developed to log Gmail inbox metadata. Gmail Logger consists of the imap_inbox_check.py Python script that retrieves metadata about messages in a Gmail inbox, grouping them by thread. The script utilizes the imaplib library to connect to Gmail’s IMAP server and retrieve information. The log_inbox.py Python script checks the state of a Gmail inbox, logs the number of threads to a tab-separated file, and saves summary information about the threads to a JSON file.
How to Set Up Gmail Logger
To get started with Gmail Logger and begin logging your Gmail inbox metadata, you’ll need to go through a setup process that involves installing the necessary dependencies and configuring access for your Gmail account. Let’s dive into the steps:
How to Install the Required Dependencies for Gmail Logger
Before you can use Gmail Logger, ensure that you have the required dependencies installed on your system. These dependencies include Git, Python, and creating an app password for your Google (Gmail) account. Here’s an overview of the installation steps:
How to Install Git for Windows
- Download Git for Windows from the official website: https://git-scm.com/download/win
- Select the 32-bit or 64-bit Git for Windows Setup
- Once the download is complete, locate the downloaded file (typically named “Git-x.y.z-64-bit.exe,” where “x.y.z” represents the version number).
- Double-click on the installer file to launch the Git for Windows setup wizard.
- In the setup wizard, you’ll see several configuration options. You can leave most of them as the default settings, but you might want to pay attention to a few:
- Select the installation location. The default location should be fine for most users.
- Choose the components to install. By default, all components are selected, and it’s recommended to keep them selected.
- Select the default editor. The default option is typically “Use Vim (the ubiquitous text editor),” but you can choose a different editor if you prefer.
- Adjusting other settings, such as the PATH environment variable or line ending conversions, is usually not necessary unless you have specific requirements.
- Once you have reviewed the settings, click “Next” to proceed.
- On the following screen, you’ll have the option to choose the SSH executable. The default option, “Use OpenSSH,” is recommended.
- Select the desired line ending conversion behavior. The default option, “Checkout Windows-style, commit Unix-style line endings,” is generally a good choice for Windows users.
- Choose the terminal emulator for Git Bash. The default option, “Use MinTTY,” is recommended.
- After making your selections, click “Next” to proceed.
- On the next screen, you can choose the default behavior of the Git Credential Manager. The default option, “Use Git’s Credential Manager,” is recommended.
- Proceed by clicking “Next” again.
- On the following screen, you can select the additional icons to be displayed on the desktop and in the Start menu. Keep the default selections or adjust them according to your preferences.
- Click “Next” to proceed.
- Finally, click on the “Install” button to start the installation process.
- Wait for the installation to complete. This might take a few moments.
- Once the installation is finished, you can leave the “Launch Git Bash” option checked if you want to start Git Bash immediately. Otherwise, you can uncheck it.
- Click “Finish” to exit the setup wizard.
- To verify that Git is installed correctly, open the Command Prompt by pressing the Windows key, typing “cmd,” and selecting the “Command Prompt” app.
- In the Command Prompt, type
git --version
and press Enter. You should see the version number of Git installed.
How to Install Python for Windows
- Download Python from the official website: https://www.python.org/downloads/windows/
- Click on the link to download the Windows installer appropriate for your system. Choose the version based on whether your operating system is 32-bit or 64-bit.
- Once the installer is downloaded, double-click on it to run the installer.
- In the Python Installer, make sure to check the box that says “Add Python to PATH” and then click on the “Customize installation” button. This will ensure that Python is added to the system’s PATH environment variable, allowing you to run Python from any command prompt.
- In the customization options, you can choose the components you want to install. It is recommended to leave the default options selected.
- On the next screen, you can choose the installation directory for Python. The default location is usually fine, but you can choose a different location if desired.
- After selecting the installation directory, click on the “Install” button to begin the installation process.
- The installer will now install Python and its associated components. This may take a few minutes.
- Once the installation is complete, click on the “Close” button to exit the installer.
- To verify that Python is installed correctly, open the Command Prompt by pressing the Windows key, typing “cmd,” and selecting the “Command Prompt” app.
- In the Command Prompt, type
python --version
and press Enter. You should see the version number of Python installed.
How to Clone the Gmail Logger Github Repository
- Open Git Bash on your computer. This was installed earlier with the Git for Windows installation.
- Navigate to the directory where you want to clone the repository. You can use the
cd
command to change directories. For example, if you want to clone the repository into your “Documents” folder, you can use the following command:
cd Documents
- Go to https://github.com/mddub/gmail-logger in your web browser
- Click Code & copy the repository’s URL. It should be
https://github.com/mddub/gmail-logger.git
- In Git Bash, use the
git clone
command followed by the repository URL. For example, the repository URL ishttps://github.com/mddub/gmail-logger.git
, so you would run the following command:
git clone https://github.com/mddub/gmail-logger.git
- Press Enter to execute the command. Git Bash will start cloning the repository to your local machine. The progress will be displayed in the console.
- Once the cloning process is complete, you will have a local copy of the repository in the current directory.
How to Create an App Password for your Google (Gmail) Account
- If your Google account has 2-Step Verification turned on, you will need to create a new app password for Gmail Logger to work.
- An app password is a 16-digit passcode that gives a less secure app or device permission to access your Google Account. Google Account App passwords can only be used with accounts that have 2-Step Verification turned on.
- Go to your Google Account
- Select Security
- Under “Signing in to Google,” select 2-Step Verification
- At the bottom of the page, select App passwords
- Enter a name that helps you remember where you’ll use the app password
- Select Generate
- The app password is the 16-character code that generates on your device.
- Select Done.
- (Copy the password to the secret.py file in the next step)
How to Create the secret.py File
- Add a file called secret.py which will contain your gmail email address & the password generated in the previous step
email = 'your-email@gmail.com' password = 'your-app-password'
- Copy the secret.py file to the gmail-logger directory that was created earlier.
How to Update the imap_inbox_check.py to Work with Python 3
Gmail Logger was originally written for Python 2 so we need to update the scripts to work with Python 3
- Replace the contents of the imap_inbox_check.py with the following code:

How to Update the log_inbox.py to Work with Python 3
Gmail Logger was originally written for Python 2 so we need to update the scripts to work with Python 3
- Replace the contents of the log_inbox.py with the following code:
"""Check the state of a Gmail inbox, then log the number of threads to a tab-separated file, and summary information about the threads to a JSON file. """ from datetime import datetime import simplejson as json import secret from imap_inbox_check import gmail_thread_info LOG_FILE = 'inbox_count.log' log_date = lambda d: d.strftime('%Y-%m-%d %H:%M:%S') json_file_date = lambda d: d.strftime('%Y-%m-%d_%H.%M.%S') unix_date = lambda d: str(int(d.timestamp())) now = datetime.now() info = gmail_thread_info(secret.email, secret.password) log_line = '%s\t%s\t%s' % (unix_date(now), log_date(now), len(info)) print(log_line) with open(LOG_FILE, 'a') as f: f.write(log_line + '\n') with open(json_file_date(now) + '.json', 'w') as f: f.write(json.dumps(info))
How to Verify Python Package Manager (pip) is Installed & Up-to-Date
- Open an Elevated Command Prompt by Right-Clicking on Command Prompt and select Run as Administrator
- Change the Directory to the C:\Users\%Username%\Documents\gmail-logger folder
- To verify that pip is installed & up-to-date, enter the following command:

How to Install Virtualenv using pip
- Enter the following command to download and install Virtualenv and its dependencies.
pip install virtualenv
- Once the installation is complete, you can create a new virtual environment. Navigate to the directory where you want to create the virtual environment and run the following command:
virtualenv env
- This command will create a new directory called “env” and set up a virtual environment within it.
- Now we can Activate the virtual environment by entering the following command:
env\Scripts\activate
- After activation, you will see the name of your virtual environment displayed in the terminal or command prompt.
- Your virtual environment is now active, and any packages you install using pip will be isolated within it.
- Now we can install the Gmail Logger requirements by running the following command:
pip install -r requirements.txt
- These packages will only be available within the virtual environment.

How to Update the relativedelta.py to Work with Python 3

Lemburg in his mx.DateTime extension. However, notice that this type does *NOT* implement the same algorithm as his work. Do *NOT* expect it to behave like mx.DateTime's counterpart. There's two different ways to build a relativedelta instance. The first one is passing it two date/datetime classes: relativedelta(datetime1, datetime2) And the other way is to use the following keyword arguments: year, month, day, hour, minute, second, microsecond: Absolute information. years, months, weeks, days, hours, minutes, seconds, microseconds: Relative information, may be negative. weekday: One of the weekday instances (MO, TU, etc). These instances may receive a parameter N, specifying the Nth weekday, which could be positive or negative (like MO(+1) or MO(-2). Not specifying it is the same as specifying +1. You can also use an integer, where 0=MO. leapdays: Will add given days to the date found, if year is a leap year, and the date found is post 28 of february. yearday, nlyearday: Set the yearday or the non-leap year day (jump leap days). These are converted to day/month/leapdays information. Here is the behavior of operations with relativedelta: 1) Calculate the absolute year, using the 'year' argument, or the original datetime year, if the argument is not present. 2) Add the relative 'years' argument to the absolute year. 3) Do steps 1 and 2 for month/months. 4) Calculate the absolute day, using the 'day' argument, or the original datetime day, if the argument is not present. Then, subtract from the day until it fits in the year and month found after their operations. 5) Add the relative 'days' argument to the absolute day. Notice that the 'weeks' argument is multiplied by 7 and added to 'days'. 6) Do steps 1 and 2 for hour/hours, minute/minutes, second/seconds, microsecond/microseconds. 7) If the 'weekday' argument is present, calculate the weekday, with the given (wday, nth) tuple. wday is the index of the weekday (0-6, 0=Mon), and nth is the number of weeks to add forward or backward, depending on its signal. Notice that if the calculated date is already Monday, for example, using (0, 1) or (0, -1) won't change the day.

How to View Exported Data from Gmail Logger in JSON File
Once you have logged the Gmail inbox metadata using Gmail Logger, the next step is to view and analyze the logged data. In this section, we’ll explore how to view the exported Gmail data and how to analyze and process the metadata to gain valuable insights.
How to Locate the JSON File
The Python script saves the JSON file with a filename based on the current date and time. Look for a file with a .json
extension in the same directory where the script was executed.
How to Open the JSON File
Right-click on the JSON file and choose an option like “Open With” or “Open” from the context menu. Select a text editor or JSON viewer application from the available options.
- If you choose a text editor (e.g., Notepad, Sublime Text, Visual Studio Code), the JSON file will open as plain text, and you can read its contents directly.
- If you choose a JSON viewer or specialized JSON editor (e.g., JSONView extension in web browsers, JSONedit), the file will be displayed in a structured format, making it easier to navigate and explore the data.
How to Navigate and Explore the JSON Data
Once the JSON file is open, you can view the data structure and its contents. JSON files are typically organized in a hierarchical format, with objects represented by curly braces {}
and arrays represented by square brackets []
.
- You can expand or collapse nested objects or arrays to explore the data structure.
- Clicking on individual elements will reveal their values or expand any sub-objects or sub-arrays they contain.
How to Interpret the JSON Data
The structure and content of the JSON data depend on the logic and implementation of the Gmail Logger script. Each entry in the JSON file represents summarized information about a Gmail thread, including properties like subject, date, sender, and unread status.
- You can interpret and analyze the JSON data based on its key-value pairs and nested structures.
- Take note of the available properties and their values to gain insights into the Gmail thread information.
Analyzing and Processing the Metadata for Insights
With the logged data exported to a JSON file, you can now analyze and process the metadata to derive valuable insights. Here are a few approaches you can take:
Statistical Analysis
Utilize statistical techniques to uncover patterns, trends, or correlations within the logged metadata. For example, you can calculate email response times, identify frequent senders or recipients, or analyze the distribution of email subjects or labels.
Data Visualization
Visualize the metadata using charts, graphs, or other visual representations to gain a better understanding of email patterns or trends. Visualizations can help identify outliers, cluster similar emails, or showcase email activity over time.
Natural Language Processing (NLP)
Apply NLP techniques to analyze the email content, such as sentiment analysis, keyword extraction, or topic modeling. This can provide insights into the tone of email conversations, prevalent topics, or emerging themes.
Automation and Integration
Integrate the logged data into your existing workflows or applications to automate processes or trigger actions based on specific conditions. For example, you can automatically categorize emails based on logged metadata, generate reports, or initiate follow-up tasks.
By analyzing and processing the logged metadata, you can unlock valuable insights, improve productivity, and gain a deeper understanding of your email communication patterns.
In the following sections, we’ll discuss best practices, tips, and real-world use cases to help you make the most of the logged Gmail inbox metadata and leverage it for various purposes.
Gmail Logger Best Practices and Tips
When using Gmail Logger to log Gmail inbox metadata, it’s important to follow best practices and implement certain tips to ensure data privacy, maintain security, and optimize performance and efficiency. This section covers some key practices and tips to consider.
Ensuring Data Privacy and Security
Secure Credentials
Keep the credentials file containing your client ID and client secret secure. Avoid sharing it publicly or storing it in insecure locations. Treat it as sensitive information to prevent unauthorized access to your Gmail account.
Limit Access
Grant access permissions to Gmail Logger only to the necessary Google account(s) and scopes required for logging the required metadata. Minimize access privileges to reduce potential risks.
Protect Exported Data
When exporting the logged data to a JSON file, ensure that the destination location is secure and accessible only to authorized individuals. Consider encrypting the exported file to provide an additional layer of protection.
Compliance with Regulations
If you’re logging sensitive or personally identifiable information (PII), ensure compliance with applicable data protection and privacy regulations, such as GDPR (General Data Protection Regulation) or CCPA (California Consumer Privacy Act).
Optimizing Performance and Efficiency for Gmail Logger
Logging Frequency
Determine an appropriate logging frequency based on your needs and the volume of emails. Consider factors such as the frequency of new emails, the amount of metadata to be logged, and the impact on system resources. Logging too frequently may overload the system, while logging too infrequently may result in incomplete or outdated data.
Error Handling
Implement robust error handling mechanisms in the Gmail Logger script. Handle potential errors gracefully, provide informative error messages, and consider implementing retry mechanisms for intermittent errors to ensure reliable logging.
Logging Filters
Optimize your email filtering criteria to capture the most relevant emails and minimize unnecessary logging. Refine your filters based on labels, date ranges, or keywords to focus on the data that is most important for your analysis or organization.
