Mail

Needing to send mail is a very common thing when building a dynamic backend or app. You'll want to inform your users of important events like a successful sign up, any major updates or changes, a change in the status of their accounts, a successful purchase, and much more.

You've got mail!

Sending Mail

Python offers the smtplib module that allows us to use the Simple Mail Transfer Protocol (SMTP) to send mail between mail servers.

Let's take use smtplib:

PYTHON
import smtplib

sender = "[email protected]"
receivers = ["[email protected]"]

message = """From: Hello <[email protected]>
To: To You <[email protected]>
Subject: Email sent using Python!

This is a test email sent using Python.
"""

try:
   smtpObj = smtplib.SMTP("localhost")
   smtpObj.sendmail(sender, receivers, message)
   print "Successfully sent email."
except SMTPException:
   print "An error occurred trying to send email."

A email requires the From, To, and Subject headers. We included all of them in the message variable. From there we defined a new mail server from localhost. Then we simply send the email.

If you are using a remote mail server, you can initialize your object like this:

PYTHON
import smtplib

server = "smtp.sabe.io"
port = 1337

smtplib.SMTP(server, port)

Sending HTML Mail

You can send HTML email just like you send plain text emails. The only difference is that you need to add a Content-type header along with a MIME-Version header.

Here's how that might look:

PYTHON
import smtplib

sender = "[email protected]"
receivers = ["[email protected]"]

message = """From: Hello <[email protected]>
To: To You <[email protected]>
MIME-Version: 1.0
Content-type: text/html
Subject: HTML email sent using Python!

This is a test HTML email sent using Python.

<h1>Sabe.io</h1>
<h2>Become a better developer</h2>
"""

try:
   smtpObj = smtplib.SMTP("localhost")
   smtpObj.sendmail(sender, receivers, message)
   print "Successfully sent email."
except SMTPException:
   print "An error occurred trying to send email."
