So all you need to do is instruct this module to send an email, sit down, relax, and watch smtplib do all the heavy lifting for you. This module essentially implements the SMTP protocol for you. Python provides you with an smtplib module that abstracts away all the complexities of SMTP. With that said, you don’t have to know how SMTP works to be able to send an email using python but it is highly valuable. I wrote an in-depth article about SMTP and I totally recommend reading it first before continuing. It is just a set of rules that govern how two mail servers can talk to each other. The protocol that enables the email technology is called the SMTP Protocol or simple mail transfer protocol. Instead of rushing it and showing you the code, it’s much better if you learn a little bit about the theory of how email works under the hood first. So instead of manually writing thousands of emails, you just write a few lines of code and you’re good to go. This is when programming comes into play because you can programmatically send an email with a dynamic body to each one of them.

Would you manually write an email for each one of them? There are thousands of them! Now you want to send a personalized email to each one of your customers addressing them with their names, and pitching new products that they might be interested in. Let’s assume this database stores the names of your customers as well as products they might be interested in based on their previous purchases. Imagine you run a business that maintains a database of a large number of customers. Instead I am going to teach you how to do that using python in FIVE lines of code. I am not going to teach you how to login to your gmail and send an email to your best friend. I am going to teach how to send an email!ĭon’t get me wrong though. In this article, I will teach you something fun.
