To catch errors, we use the “try” and “except” blocks.
The code looks pretty straightforward, right? Let’s take a closer look at it and add some error handling (see the #explanations in between). However, it won’t give you the opportunity to check how your HTML email template is rendered. It will help you verify whether your code is working and point out the possible problems if there are any. In order to run SMTP server on port 25, you’ll need root permissions: sudo python -m smtpd -n -c DebuggingServer localhost:25 Set your SMTP server to localhost:1025 python -m smtpd -n -c DebuggingServer localhost:1025 It is compatible with all operations systems. It has a DebuggingServer feature, which will discard messages you are sending out and will print them to stdout. For this purpose, Python offers an smtpd module. If you prefer working in the local environment, the local SMTP debugging server might be an option. Your domain won’t be blacklisted for spam.You won’t flood your own inbox with testing emails.This is vital when you test bulk email sending or work with an email database. You won’t hit your friends’ and customers’ inboxes.When creating a new app or adding any functionality, especially when doing it for the first time, it’s essential to experiment on a test server.
To make sure that the module has been imported properly and get the full description of its classes and arguments, type in an interactive Python session: help(smtplib)Īt our next step, we will talk a bit about servers: choosing the right option and configuring it. You can import the module using the following statement: import smtplib No extra installations or tricks are required.
The first good news about Python is that it has a built-in module for sending emails via SMTP in its standard library. Note: written and tested on Python 3.7.2.
Configuring a server for testing (do you know why it’s important?).This tutorial will guide you through the most essential steps of sending emails via an SMTP server: We assume you’ve already had a web app built with this language and now you need to extend its functionality with notifications or other emails sending. What do you need to send an email with Python? Some basic programming and web knowledge along with the elementary Python skills.
