Simple e-mail composition & decomposition
Project description
GitHub | PyPI | Documentation | Issues | Changelog
eletter provides functionality for constructing & deconstructing email.message.EmailMessage instances without having to touch the needlessly complicated EmailMessage class itself. A simple function enables composition of e-mails with text and/or HTML bodies plus attachments, and classes are provided for composing more complex multipart e-mails.
Installation
eletter requires Python 3.6 or higher. Just use pip for Python 3 (You have pip, right?) to install eletter and its dependencies:
python3 -m pip install eletter
Examples
Constructing an e-mail with the compose() function:
import eletter
TEXT = (
"Oh my beloved!\n"
"\n"
"Wilt thou dine with me on the morrow?\n"
"\n"
"We're having hot pockets.\n"
"\n"
"Love, Me\n"
)
HTML = (
"<p>Oh my beloved!</p>\n"
"<p>Wilt thou dine with me on the morrow?</p>\n"
"<p>We're having <strong>hot pockets</strong>.<p>\n"
"<p><em>Love</em>, Me</p>\n"
)
with open("hot-pocket.png", "rb") as fp:
picture = eletter.BytesAttachment(
content=fp.read(),
filename="enticement.png",
content_type="image/png",
)
msg = eletter.compose(
subject="Meet Me",
from_="me@here.qq",
to=[eletter.Address("My Dear", "my.beloved@love.love")],
text=TEXT,
html=HTML,
attachments=[picture],
)msg can then be sent like any other EmailMessage, say, by using outgoing.
For more complex e-mails, a set of classes is provided. Here is the equivalent of the HTML-with-image e-mail with alternative plain text version from the email examples page in the Python docs:
from email.utils import make_msgid
import eletter
text = eletter.TextBody(
"Salut!\n"
"\n"
"Cela ressemble à un excellent recipie[1] déjeuner.\n"
"\n"
"[1] http://www.yummly.com/recipe/Roasted-Asparagus-Epicurious-203718\n"
"\n"
"--Pepé\n"
)
asparagus_cid = make_msgid()
html = eletter.HTMLBody(
"<html>\n"
" <head></head>\n"
" <body>\n"
" <p>Salut!</p>\n"
" <p>Cela ressemble à un excellent\n"
' <a href="http://www.yummly.com/recipe/Roasted-Asparagus-'
'Epicurious-203718">\n'
" recipie\n"
" </a> déjeuner.\n"
" </p>\n"
f' <img src="cid:{asparagus_cid[1:-1]}" />\n'
" </body>\n"
"</html>\n"
)
image = eletter.BytesAttachment.from_file(
"roasted-asparagus.jpg",
inline=True,
content_id=asparagus_cid,
)
msg = (text | (html ^ image)).compose(
subject="Ayons asperges pour le déjeuner",
from_=eletter.Address("Pepé Le Pew", "pepe@example.com"),
to=[
eletter.Address("Penelope Pussycat", "penelope@example.com"),
eletter.Address("Fabrette Pussycat", "fabrette@example.com"),
],
)
