Using the library

For a detailed usage example see example.py.

You will need an application-specific password for your Google account. Reference 1, Reference 2

Installing and using the library

First, you need to install the library using pip:

$ pip install pyemail_sender

Then, import it and initialize it like so:

from pyemail_sender import GmailPyEmailSender

email_conf = {'type': 'gmail',
              'config': {'api_key': 'your api key', 'email_address': '[email protected]'}}
pymail = GmailPyEmailSender(config=email_conf)

If you want to use a yml file to load the configuration, you can use the PyEmailSenderConfig class:

from pyemail_sender import PyEmailSenderConfig
import os

config_path = str(os.path.join('confs', 'conf.yml'))
config = PyEmailSenderConfig(config_src=config_path)
email_conf = config.get_pyemail_sender_config()

Two example YAML files can be found in the confs folder. For more details on how to use this YAML configuration loader see this Readme.

Examples of usage

Send Simple Email

pymail.send_email(subject='A simple email',
                  to=[email_conf['email_address']],
                  text='Email body text goes here')

Send HTML Email

pymail.send_email(subject='A simple HTML email',
                  to=[email_conf['email_address']],
                  html='<h1>Email body with HTML goes here</h1>')

Send Email with all the arguments

pymail.send_email(subject='Email with all possible arguments',
                  sender=email_conf['email_address'],
                  to=[email_conf['email_address']],
                  cc=[email_conf['email_address']],
                  bcc=[email_conf['email_address']],
                  reply_to=email_conf['email_address'],
                  html='<h1>Test <b>HTML</b> body</h1>',
                  attachments=['my_file.txt'])

All of these examples can be found in example.py.

Manually install the library

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

You need to have a machine with anaconda installed and any Bash based shell (e.g. zsh) installed.

$ conda -V
conda 4.10.1

$ echo $SHELL
/usr/bin/zsh

Install the requirements

All the installation steps are being handled by the Makefile.

First, modify the python version (min_python) and everything else you need in the settings.ini.

Then, execute the following commands:

$ make create_env
$ conda activate pyemail_sender
$ make dist

Now you are ready to use and modify the library.

Run the Unit Tests

If you want to run the unit tests, execute the following command:

$ make tests

Continuous Integration

For the continuous integration, the CircleCI service is being used. For more information you can check the setup guide.

For any modifications, edit the circleci config.

Update PyPI package

This is mainly for future reference for the developers of this project. First, create a file called ~/.pypirc with your pypi login details, as follows:

[pypi]
username = your_pypi_username
password = your_pypi_password

Then, modify the python version (min_python), project status (status), release version (version) and everything else you need in the settings.ini.

Finally, execute the following commands:

$ make create_env
$ conda activate pyemail_sender
$ make release

For a dev release, change the testing_version and instead of make release, run make release_test.
