Python-based mass mailer script

Author: Christian Federmann [email protected]

Version: 2013-03-15

Usage: $ mass_mailer.py [--dry-run] <config.ini> <mail.html|txt> <emails.csv>

Sends an individualised version of mail.html|txt to all recipient email addresses contained in emails.csv; configuration details such as mail server or header fields are read from config.ini.

The following fields inside config.ini are required:

SMTP=smtp.example.org
[email protected]
SUBJECT=Mails without subject would not make sense, right?!

There also are some optional settings:

[email protected] (defaults to FROM address)
[email protected]
FIRST_LASTNAME=Sir or Madam

The mail.html|txt file may contain HTML markup and should be saved in UTF-8 encoding; there is one "special" placeholder {{FIRST_LASTNAME}} which can be used to insert the personalised recipient name into the email. If the name cannot be resolved from the email address, the script will use FIRST_LASTNAME from config.ini, iff available, defaulting to "Sir or Madam" otherwise.

A template ending with extension ".txt" triggers sending of plain text emails.

Email addresses should be given in comma-separated list form, e.g.:

# firstname,lastname,email
John,Doe,[email protected]
,,[email protected]

You can use the optional "--dry-run" flag to run the script in testing mode which will do everything except sending out the actual emails.

It is a wise idea to test any new mail.html|txt or config.ini with your own email address first. The author does not any responsibility for emails sent out with this tool. By using the script, you accept this.
