pymassmailer
Matthew Levandowski - December 2013
Overview
pymassmailer is a generic mass mailer app which can use html jinja2 templates for data.
It sends an email to the target email with two types 1) HTML 2) Plain
We will try the template with .html for rich html and .txt for plain, if one isn't found we will only send the correct one.
Both will rendered with Jinja2
Py Mass Mailer Can be created by passing the configuration for sending a mail, pkg_name is required so we can find your email templates but depending on your configuration server, username, password may not be required.
Only server, username, password, port, sender and template_dir can be configured. If you need to change other settings such as logging. Please pass a Config object.
Config object is specified below: class Config(object):
"""
Py Mass Mailer configuration
"""
EMAIL_HOST = 'localhost'
EMAIL_USERNAME = ''
EMAIL_PWD = ''
EMAIL_PORT = 25
EMAIL_SENDER = ''
EMAIL_TEMPLATE_DIR = ''
LOGGER_NAME = 'pymassmailer'
LOGGER_LEVEL = logging.NOTSET
DEBUG_LEVEL = 0
SMTP_EHLO_OKAY = 250
SMTP_AUTH_CHALLENGE = 334
SMTP_AUTH_OKAY = 235
To set just use config = pymassmailer.config(EMAIL_HOST='someserver', ...)
Installation instructions
Add the following to the INSTALLED_APPS in the settings.py of your project:
pip install pymassmailer
Example Usage instructions
I have a sample below that loads an excel file with pandas and mass mails the emails from it:
Example script:
import PyMassMailer
import os
import pandas as pd
SMTP_SERVER = 'localhost'
TEMPLATE_DIR = os.path.dirname(os.path.abspath(__file__)) + '\\templates'
TEMPLATE_NAME = 'message'
FROM_ADDR = "individualbusiness@somewhere.com"
SUBJECT = "Reminder: Waiting for Information."
SOURCE_FILE = 'mailmerge-final.xls'
data = pd.read_excel(SOURCE_FILE, 'Master')
# Setup mass mailer class
email_sender = PyMassMailer(__name__, server=SMTP_SERVER, default_sender=FROM_ADDR, template_dir=TEMPLATE_DIR)
# loop through email addresses
for count,row in data.iterrows():
print row
TO_ADDR = row['Email']
print 'sending email to: %s' % TO_ADDR
email_sender.send_email(TO_ADDR, TEMPLATE_NAME, SUBJECT , name=row['Name'])and in templates dir
