Introduction

gmailsort is a simple Python script that uses the Gmail API to sort your Gmail messages by sender domains. It allows you to automatically create labels named by the sender domains of the analyzed messages and then to sort the messages under these labels. This script does not create Gmail filters, it just sorts your messages at the time of calling it. In order to use this script and access your Gmail account via API, you need to have a Google Cloud project. Detailed steps are described below. Besides that, you just have to install the required Python dependencies and call the script directly from the project directory. Take a look at the help dialog of the script for more details about command-line options.

Requirements to use Gmail API

Google provides a central location to maintain your used APIs to access Google services. In order to access the Gmail API, you have to do the following steps:

1. Create a new Google Cloud project.

2. Enable the Gmail API for your project.

3. Add yourself as test user at the OAuth consent screen.

4. Create OAuth 2.0 client credentials for your project and store them under credentials.json in the project directory.

Install Python dependencies

pip install -r requirements.txt

Usage examples

1. To analyze the messages of your inbox with resepect to their sender domains and to see the envisaged label structure (without actually creating labels), call

   ./gmailsort.py -p user analyze -s INBOX -d test -v

   If this is called for the first time with the given profile name, a Gmail login dialog will open and you have to login and allow the app to access your messages. Afterwards, an initial message data download is issued. This will probably take several minutes depending on the amount of messages in your Gmail account. All subsequent calls will be much faster and just synchronize the differences between local and remote data.

   INBOX is a Gmail built-in label name for your inbox. User-defined labels can have any name except these and can be organized hierarchically. To name a hierarchical label, use a single string and separate the hierarchies with slashes, e.g., foo/bar.

   Specifying a destination label (as test in this case) is optional. Otherwise, labels will be created top level. If you are happy with the envisaged labels structure, you can actually create it by calling the command again and adding the command-line option -l or --create-labels.

2. To find labels matching the sender domains of your inbox messages (without modifying message labels), call

   ./gmailsort.py -p user find -s INBOX -v

   This will only show meaningful results if you have created labels with the analyze command or by hand beforehand.

   Matching is done by case insensitive name comparison, e.g., if your inbox contains multiple messages from the domain foobar and a label called test/foobar is existing, it will be displayed as matching target label. Only the lowest hierarchy level will be used for name comparision, i.e., a label called foobar/test will not be displayed as match.

   If the messages from each domain shall be sorted under their respective labels, just call the command again and add the command-line option -m or --sort-messages. If multiple labels match a domain such as one/foobar and two/foobar, you can use the destination label command-line option -d to restrict the search to be started at a specific label, e.g., -d two will only find the second label as single label.
