python-emails
=============
Modern email handling in python.
.. code-block:: python
m = emails.Message(html=T("<html><p>Build passed: {{ project_name }} <img src='cid:icon.png'> ..."),
text=T("Build passed: {{ project_name }} ..."),
subject=T("Passed: {{ project_name }}#{{ build_id }}"),
mail_from=("CI", "ci@mycompany.com"))
m.attach(filename="icon.png", content_disposition="inline", data=open("icon.png"))
response = m.send(render={"project_name": "user/project1", "build_id": 121},
to='somebody@mycompany.com',
smtp={"host":"mx.mycompany.com", "port": 25})
if response.status_code not in [250, ]:
# message is not sent, retry later
...
See `the same code, without Emails <https://gist.github.com/lavr/fc1972c125ccaf4d4b91>`_.
Emails code is not much simpler than `the same code in django <https://gist.github.com/lavr/08708b15d33fc2ad718b>`_,
but it is still more elegant, can be used in django environment and has html transformation methods
(see ``HTML Transformer`` section).
Features
--------
- HTML-email message abstraction
- Method to transform html body:
- css inlining (using peterbe's premailer)
- image inlining
- DKIM signature
- Message loaders
- Send directly or via django email backend
Examples
--------
Create message:
.. code-block:: python
import emails
message = emails.html(html=open('letter.html'),
subject='Friday party',
mail_from=('Company Team', 'contact@mycompany.com'))
Attach files or inline images:
.. code-block:: python
message.attach(data=open('event.ics'), filename='Event.ics')
message.attach(data=open('image.png'), filename='image.png',
content_disposition='inline')
Use templates:
.. code-block:: python
from emails.template import JinjaTemplate as T
message = emails.html(subject=T('Payment Receipt No.{{ billno }}'),
html=T('<p>Dear {{ name }}! This is a receipt...'),
mail_from=('ABC', 'robot@mycompany.com'))
message.send(to=('John Brown', 'jbrown@gmail.com'),
render={'name': 'John Brown', 'billno': '141051906163'})
Add DKIM signature:
.. code-block:: python
message.dkim(key=open('my.key'), domain='mycompany.com', selector='newsletter')
Generate email.message or rfc822 string:
.. code-block:: python
m = message.as_message()
s = message.as_string()
Send and get response from smtp server:
.. code-block:: python
r = message.send(to=('John Brown', 'jbrown@gmail.com'),
smtp={'host':'smtp.mycompany.com', 'port': 465, 'ssl': True})
assert r.status_code == 250
Or send via Django email backend:
.. code-block:: python
from django.core.mail import get_connection
from emails.message import DjangoMessageProxy
c = django.core.mail.get_connection()
c.send_messages([DjangoMessageProxy(message), ])
HTML transformer
----------------
Message HTML body can be modified with 'transformer' object:
.. code-block:: python
>>> message = emails.Message(html="<img src='promo.png'>")
>>> message.transformer.apply_to_images(func=lambda src, **kw: 'http://mycompany.tld/images/'+src)
>>> message.transformer.save()
>>> message.html
u'<html><body><img src="http://mycompany.tld/images/promo.png"></body></html>'
Code example to make images inline:
.. code-block:: python
>>> message = emails.Message(html="<img src='promo.png'>")
>>> message.attach(filename='promo.png', data=open('promo.png'))
>>> message.attachments['promo.png'].is_inline = True
>>> message.transformer.synchronize_inline_images()
>>> message.transformer.save()
>>> message.html
u'<html><body><img src="cid:promo.png"></body></html>'
Loaders
-------
python-emails ships with couple of loaders.
Load message from url:
.. code-block:: python
import emails.loader
message = emails.loader.from_url(url="http://xxx.github.io/newsletter/2015-08-14/index.html")
Load from zipfile or directory:
.. code-block:: python
message = emails.loader.from_zipfile(open('design_pack.zip'))
message = emails.loader.from_directory('/home/user/design_pack')
Zipfile and directory loaders require at least one html file (with "html" extension).
Install
-------
Install from pypi:
.. code-block:: bash
$ [sudo] pip install emails
Install on Ubuntu from PPA:
.. code-block:: bash
$ [sudo] add-apt-repository ppa:lavrme/python-emails-ppa
$ [sudo] apt-get update
$ [sudo] apt-get install python-emails
TODO
