Amazon SES helper script using boto
# -*- coding: utf-8 -*-
"""
amazon_sender.py
~~~~~~~~
Python helper class that can send emails using Amazon SES and boto.
The biggest feature of this class is that encodings are handled properly.
It can send both text and html emails.
This implementation is using Python's standard library (which opens up for a lot more options).
Example::
amazon_sender = AmazonSender(AWS_ID, AWS_SECRET)
amazon_sender.send_email(sender=u'朋友你好 <[email protected]>',
to='[email protected]',
subject='Hello friend',
text='Just a message',
html='<b>Just a message</b>',
sender_ascii='Ascii Sender <[email protected]>')
