Quick-and-Dirty Email Sender

Project description


Quick-and-Dirty Email Sender

Build Status Coverage Status PyPI version

Emails are ubiquitous, but not super-straightforward from a programming standpoint. The standards in use (SMTP, MIME) are powerful, but complex if you want to do anything nicer than a simple plain-test email. This library was built and iterated upon for my personal projects, and it might just help you too.

Supports both Python >=v2.7 and >=3.4.


pip install quick-email


Send Email

quick_email.send_email(host, port, send_from, subject[, send_to[, send_cc[, send_bcc[, plain_text[, html_text[, attachment_list[, inline_attachment_dict[, username[, password[, timeout[, require_starttls]]]]]]]]]]])

My super-useful utility function. Creates and sends an email in one fell swoop. All parameters are passed to the functions below.

Create Message

quick_email.build_msg(send_from, subject[, send_to[, send_cc[, send_bcc[, plain_text[, html_text[, attachment_list[, inline_attachment_dict]]]]]]])

Creates a email.message.Message for deferred sending or additional preparing.

Email addresses can be a string (either of form or Example Name <>), or a tuple, as returned by email.utils.parseaddr.

send_from is a single email address.

subject is the Subject string of the email.

send_to, send_cc, and send_bcc are all either singular email addresses, or lists of email addresses if you have multiple recipients. At least one address must be present among the parameters, otherwise an AssertionError will be raised.

plain_text is the plain-text part of the email. html_text is the HTML part of the email. You can include one or both, but if no text is present, an AssertionError will be raised.

attachment_list is an optional list of quick_email.Attachments.

inline_attachment_dict is an optional dict of str: quick_email.Attachment form. The key is the CID of your attachment. In many email clients, you can include images inline in the HTML (ie <img src="...">). However, if the image you want to display is an attachment (and not at some URL), it's a little trickier. You must give your attachment a Content-ID (CID), and your img tag must look like <img src="cid:my_attachment_cid">. This may be preferred to the inline-base64 encoding (ie <img src="data:image/jpeg;base64,...">).

class quick_email.Attachment(filename, bytes)

filename is the filename string.

bytes is the bytes-like object of the content.

Send Message

quick_email.send_msg(msg, host, port[, username[, password[, timeout[, require_starttls]]]])

Sends a email.message.Message to its recipients.

msg is the email.message.Message, which you may have built using quick_email.build_msg, or handcrafted youself.

host is the host string to connect to. Usually a FQDN, or an IP address.

port is the port number to connect to. Usually 25 for un-encrypted email.

username is the username of a username/password combo used to authenticate. Leave it off if your service is unauthenticated.

password is the password of a username/password combo used to authenticate. Leave it off if your service is unauthenticated.

timeout is the timeout interval (in seconds). If not specified, the global default timeout setting will be used.

require_starttls is a flag whether to request the message sending be encrypted. Defaults to False, but turn it on if you can.
