Motivation

Sending emails may seem to be a simple task. But there is some complicated stuff to consider:

  1. An email should be sent in a parallel thread, so it does not pause the whole project

  2. An email should be beautiful and support different formats — Text and HTML.

  3. Security issues. Does your email server require SSL? Sending from Gmail.

Simple Email send

Sending emails is no rocket science in Python. As usual, batteries are already included, so we need to insert them:

import smtplib, ssl
from email.mime.text 
import MIMETextfrom email.mime.multipart 
import MIMEMultipart

Now, as batteries are in, we only need to press the red button:

server = smtplib.SMTP(email_smtp_server, email_port))
server.login(email_login, email_password)
server.sendmail(email_from, email_to, message.as_string())

Ooops, what are all these variables? Sure, we need to supply our code with the email properties, subject, and email text.

Email properties are the email_smtp_server, which is a simple string, and the email_port, which is an integer.

All the rest goes to the message variable, which is something more complex:

body = "<html>"
body += "<h2>Guten Tag!</h2><br><br>"
body += "<b>This is an automatic email.</b><br>"
body += "Please do not reply.<br><br>"
body += "Best regards,<br>"
body += "Your server.<br>"
body += '<img src="http://realitycheckbbs.org/images/fido.jpg">'
body += "</html>"
